Innova Code Reader first try

Discussion in 'General Motoring' started by Richard Steinfeld, Mar 18, 2005.

  1. Hyundaitech please copy.

    Here's what happened with the Innova code reader that I bought
    last week. It's on sale right now at Kragen and affiliated stores
    for $100 (USD) after the rebate.

    I opened the package and read the documentation last night. Three
    separate books are provided, one each in English, Spanish, and
    French. The manufacturer isn't a cheapskate: three AAA batteries
    are packed with the unit, they're not cheapo batteries but are
    instead alkalines of a brand that I recognize.

    The documentation is especially good. The history and reasoning
    behind the OBD II (On Board Diagnostics, 2nd generation) system
    is explained in everyday language. The test procedure is
    described quite well. The documentation is exceptionally good --
    it's almost a model of how manuals should be written and edited.
    My only complaint is that apostrophes are misused for plurals of
    acronyms -- a growing trend that I dislike because it confuses
    readers. A multi-page table of universal codes and their
    explanatins are presented. Additional proprietary code sets are
    provided for five popular makes of autos -- Hyundai isn't one of
    them. The proprietary Ford codes are very extensive; the Toyota
    list is very short. Among the Ford codes, I spotted very simple
    matters that are easily nailed with old-time instruments, or just
    his eyeballs, by any mechanic with half a brain.

    A short backgrounder:
    Today's cars employ sophisticated diagnostic systems that monitor
    performance of a number of emissions and "runability" components
    and sytems. Since 1996, the US Government requires that all cars
    must share standard code reader hookups and code designations.
    This standardization allows the use of a single code reader with
    any auto sold in the United States today. Professional "Scan
    Tools" work the same way, but are more sophisticated -- these
    instruments are too expensive for the home user.

    The vehicle's computer constantly monitors these devices and
    makes adjustments that ensure the best efficiency and cleanest
    output from the tailpipe under the changing conditions of any
    road trip. When one of these systems does not perform according
    to specifications, a trouble code is generated by the computer
    and stored for retrieval. The seriousness of a trouble condition
    is evaluated by the computer and action is taken, sometimes
    immediately, sometimes after a few repetitions of the event. If
    attention is warranted, the computer lights the "check engine"
    lamp, either steady or flashing.

    The code reader connects under the dashboard via a cable to a
    mating socket. Pressing a button on the reader instructs the
    car's computer to download any stored malfunction codes; these
    codes are presented on the screen of the code reader in about
    five seconds.

    The Innova Owner's Manual explains the different states of code
    storage, and what the various screen indications mean. Individual
    systems are tested by the car's computer; each system is tested
    using its own special program -- a routine that may require the
    car to be driven either casually, or in a specific way, in order
    to store the results in the computer for evaluation. Each of
    these routines is named a "monitor." All monitors on a given
    vehicle are polled by the code reader; all results are displayed,
    regardless of the seriousness -- and the seriousness also
    registers on the screen. For example, a glitch that's not
    critical may be stored in a state named "pending" -- that is,
    pending repetition of the stimuli to see if the malfunction will
    happen again. If there are more than one stored code, the user
    can scroll through the results. A "pending" code won't trigger
    the "check engine" light, but it'll be shown on the code reader's
    screen.

    I searched for my 2000 Sonata's socket for about two minutes
    before finding it exactly where Hyundaitech said it was. The
    socket is straight vertical, just to the right of the steering
    column, just behind the bottom edge of the dashboard. It took a
    bit of work to get the plug aligned correctly with the socket.
    Once connected, I had the report on my car in less than a minute.
    The result was "zero," which confirmed that the car that I bought
    two weeks ago is free of troubles in these major systems -- it
    should therefore pass a smog test with flying colors, as it did
    three months ago.

    All monitors that have reported were indicated with solid
    characters. But two of these characters were blinking, indicating
    that their corresponding test data was missing in the car's
    computer. The word "done" was missing from the reader's screen,
    showing that all available monitors had non been accounted for.

    **** Here's where I'd like Hyundaitech to comment:
    Two of the monitors were not run (the blinking ones). These were
    the Catalyst Monitor ("C") and the Oxygen Sensor Monitor ("O").
    What do I need to do to run the tests in order to obtain the data
    that the computer needs to report on these two components? Also,
    if they're on the Hundai technical web site, how do I find the
    information?

    If any of you are interested in buying this device and live near
    a Kragen, Schucks, or Checker store, the sale is on, I think,
    until March 26th. It may also be available on their web site -- I
    don't know. Note that there's a different, smaller code reader on
    sale at the same time for less money. I can't comment on it; I've
    already had experience with an earlier Innova (Equus) code
    reader, and it was a winner.

    Could the documentation be better? Of course. It's a little
    confusing, but most things should come clear in a few
    read-throughs. However, the book is so vastly better than the
    instructions with most products that Innova deserves special
    commendation for doing such a user-centric job. The four buttons
    on the reader make a cheap, ratty sound when you release them. No
    matter -- I like this gizmo.

    Thanks, Hyundaitech.

    Basically, the fact that the monitors haven't run means that the computer
    was cleared relatively recently and the computer hasn't finished running
    the tests. What's necessary to get them to run is to drive the vehicle.
    The catalyst and O2 monitors typically are among those requiring the
    longest drive time.

    In my location, many emissions tests are done just by plugging in a tool
    similar to yours and checking to see if the monitors have run and that
    there are no codes. I had a customer who drove her vehicle such short
    distances that I had to test drive the car home and back overnight for the
    monitors to run so she could pass her emissions test.

    Oh, and btw, I also really hate the fact that so many people don't seem to
    know the difference between plural and possessive. It's everywhere.

    This is what puzzled me. This past Monday, I drove a fairly long
    distance, much of it along a winding coastal California road,
    some of it on freeway, and some on city streets -- with a handful
    of stops along the way. My driving the following two days was
    mixed, but mostly freeway, with the code reader download the
    morning after. So, I'm a bit confused. From Innova's
    instructions, I got the impression, as you said, that a bit of
    driving was required in order to run these monitors. So, what I'm
    thinking now is that a few short hops can erase a prior data set
    from a long run -- in other words, new data will push old data
    out of the buffers. Otherwise, I don't understand why I was
    missing these two monitors.

    Since this is a public forum, I've been explaining a bit --
    sharing my process with this gizmo for others to follow. If there
    are no objections, I'll be happy to keep it up.

    One of my motives is this: with the recent advances in
    computerized engine controls, older mechanical knowledge has got
    to be enhanced with knowledge of the new systems, as well as
    diagnostic methods. That's been a lot for mechanics to chew on,
    despite all the self-diagnosis. We've got a whole bunch of new
    terms, and unfortunately, many of these terms are a long stretch
    when it comes to the sensibility of the names. (I recall "Key On
    Engine Off: KOEO." But why isn't KOEO "Key Off Engine On?"
    Better would be something like "Power Up Engine Running/Power Up
    Engine Stopped." I'm into very clear technical terminology --
    terminology that eliminates potential confusion.

    With this technical revolution has come a new problem for the
    consumer: the driver is helpless if there's a road breakdown, and
    sometimes at the mercy of a preditory mechanic far from home.
    Being able to read one's own codes on-the-fly gives the customer
    important knowledge is such a situation.

    |

    I know. I like clear writing. Plural/possessive confusion with
    apostrophes muddies things up, like the use of "insure" for
    "ensure." I really appreciate good technical writing -- it can
    be a pleasure to read.

    Well, I'm not really sure why the monitors haven't run, then. Perhaps it's
    a difficulty with the tool reading the monitor on your specific car, but I
    doubt it. I wouldn't worry much about it, either. If you've recently
    passed emissions and the check engine lamp is not on, there can't be much
    wrong. What sort of emissions test did they do on your vehicle? Was it
    tailpipe, treadmill, or OBD-II (read codes and monitors)?

    I definitely agree about the knowledge. There are many people who don't
    understand anything more than the fact their car is broken and the price
    to repair it. As a result, conclusions as to rip-offs, etc. get made
    solely on the basis of price. At least with a little knowledge, you can
    probably tell whether someone is handing you a line of b.s. to separate
    you from your money.

    Oh, and if you ever find any of that good technical writing, let me know.
    There's no way it can't be better than the ridiculous things I read every
    day.

    Perhaps it's

    car, but I
    | doubt it. I wouldn't worry much about it, either.

    But the issue is that I want to read all the emissions codes
    because one of the reasons that I bought the reader is to be
    prepared for a smog test in advance. And also, of course, to keep
    the car tuned up. So, It's important to me to have perfect
    readout of all monitors. The present situation is bothering me.

    I re-connected the reader this afternoon, and got the same result
    as yesterday -- no report on the catalytic converter and the
    oxygen sensor. So, I went out this evening and left the reader
    connected -- it retrieved codes every 15 seconds during a
    25-minute drive, a 10-minute drive, and the last one, 12 minutes.
    No change.

    If you've recently
    | passed emissions and the check engine lamp is not on, there
    can't be much
    | wrong. What sort of emissions test did they do on your
    vehicle? Was it
    | tailpipe, treadmill, or OBD-II (read codes and monitors)?
    |

    Good questions. I bought the car 2.5 weeks ago. California
    requires that the car be smogged upon title transfer -- three
    months prior test is fine. The car flunked a smog test, was
    repaired, and then passed -- all in December. I do not know what
    work was done.

    Around the same time, the seller took the car for an oil change
    at a franchised tuneup shop. It's the only receipt that I have
    for the vehicle. The slip says that he was charged $25 to reset
    the "check engine" light. So, I assume that all stored codes were
    cleared at that time, too.

    I'm fairly certain that the smog test was run with a
    dynomometer -- folks in the Central Valley have been screaming
    bloody murder that they have to breathe all our smog, which blows
    to them over the mountains. Thus, about two years ago, the
    treadmill test was added for the SF Bay Area.

    I'll assume that the test station also reads the OBD II monitors
    and codes -- after all, if you wanted to ensure that your air was
    as free of junk as you could make it, and that people didn't game
    the smog test (as a mechanic, you know about that, right?) you'd
    want to do this, too, because you might nab some lurking
    problems. I don't know this for a fact, however. So far, I've
    been pretty impressed with the Air Resources people, but the
    whole thing can be a pain. Still, we've all got to breathe, and
    we've got a lot of folks with asthma right around here -- near a
    couple of refineries and belching diesels on the freeways and
    also at the transcontinental railroad terminals; it's the tsunami
    of goodies from China coming to enrich our lives.

    Yes; I direct the reader's attention to the line above where I
    said that a person was charged $25 to reset his "check engine"
    light. That's a 2-minute task with the code reader that I just
    bought. The scenario that I presented earlier on this board in
    which the driver pulls into a small town, his car a'knockin' and
    a'belchin,' nervous and desperate for a repair, and gets hustled
    with what I'll call the "We'll have to connect your car to the
    computer" gambit. "That'll be ninety-five dollars for the
    hookup -- it's very complicated." And, "We won't be able to
    connect it until Friday -- we're real busy, backed up you know."
    And, "You can stay at Ed's Motel down the street until I can get
    to your car."

    I presented this scenario to my friend yesterday, and he replied,
    "That's it! That's exactly what happened to me in Lone Pine! We
    didn't get out of there for three days." There's a lot of really
    fine mechanics out there. But there are those rascals, too.

    | Oh, and if you ever find any of that good technical writing,
    let me know.
    | There's no way it can't be better than the ridiculous things I
    read every
    | day.

    Yes, I know. Most of the automotive stuff is really awful
    regardless of where it comes from. A long time ago, I was really
    inspired by the house writing style of Eastman Kodak. I don't
    know if they've retained it, but it ran throughout almost all of
    their publications. Their materials were incredible. Once you see
    good technical documentation, the usual stuff will have you
    screaming and cursing a whole lot, because then you'll know how
    beneficial it can really be and how the stuff you've been
    suffering with has been messing up your life.

    There are a number of reasons why most technical documentation is
    poor. I won't go into them all right now; this would get rather
    long. But let's just say that there are some people who could do
    a much better job at empathizing with the guy who has to use the
    stuff. Writing isn't adequately budgeted; writers are brought
    onto projects way, way too late by managers. The writers aren't
    allowed the time that it takes to get to know the product, yet
    they have to describe it! Product managers just want to shove
    the product out the door -- which is understandable because it's
    probably barely on deadline. Documentation is often regarded as a
    pain in the neck. The wrong writers are hired -- many tech
    writers don't have a good feel for what they're documenting. I
    think that it's very important for the writer to be able to put
    himself in the user's shoes and write completely from that space.
    Unfortunately, it's mostly the opposite: the writing is done
    top-down, from the viewpoint of the engineer. There's no doubt of
    one thing: good documentation costs money. And it's worth it.

    That engineer designs the oil pan, but he does not know what it's
    like to be lying underneath a car with oil dripping into your
    eyes, trying to feel with your one free oily hand whether the
    wrench is a 15/64 inch or a 192/256 inch. And that's assuming
    that you've guessed the size of that damn bolt correctly! And
    neither does the writer! And the writer got his information from
    that engineer. I'll stop here, OK?

    If there's something I need to know about running these two
    nagging tests, please let me know. For example, is it neccessary
    for the car to be run at a sustained speed for a given period of
    time?
    I'll check in with Innova on Monday about the code reader and
    report back.

    Good chatting with you.

  8. The difference between plural and possessive forms isn't always clear.
    Words that don't have a specific plural form are supposed to be written
    with an apostrophe between the word and the added "s" at the end, which
    makes it look like a possessive form. Names are a good example of this.
    Is the plural of "Hyundai" supposed to be "Hyundais" or "Hyundai's"?
    Either could be correct, but I'll bet it's the latter.

    Beg pardon, but I don't agree with the "supposed to be" part of
    this. I say that it's wrong, and it's the writer's and editor's
    job to use their craft in order to avoid the confusion.

    "Hyundai's bumper:" correct.
    "A bunch of Hyundai's:" wrong, wrong, wrong.

    This is the second time in which I've recently found a person
    claiming that this butchery is correct!
    What is happening to us?

    Go here:
    http://www.angryflower.com/aposter.html

    Here:
    http://www.apostrophe.fsnet.co.uk/

    Try this:
    http://www.users.bigpond.com/J_fersOffice/sample.htm

    Many people have been apostrophizing acronyms for plurals. It's
    the lazy way out. Look at this:
    Plural of ATM: "ATM's"
    How about "ATMs?"
    Which one is clear? Which is confusing?

    This awful transgression had inflicted the railroad publishing
    industry -- the cause was a locomotive on the Pennsylvania
    Railriad that was named the "K4s." In order to be able to deal
    with this, the editor of Trains Magazine decided to twist the
    entire English language instead. Plural became "K4s's," However,
    professional consistency dictated that other locomotives were now
    "Alco's."

    Applying a bit of work to this solves the problem:
    Instead of "K4s's" (or "K4s'"), we can write, "The K4s engine
    class," or "A group of K4s locomotives."
    With acronyms, clearing this up is surprisingly easy, because all
    we have to do is to write the acronym itself in upper case (which
    is normal) and then put the trailing pluralization in lower case
    like this: ATMs.

    A good writer and a good editor should always work for clarity
    and eliminate obfuscation -- that is, unless we're writing
    mystery novels.

    Clear now?
    I rest my case.

    I recall learing (in High School English, I believe) that acronyms were the
    only allowable (but not required) use of the apostrophe to indicate
    plurals. The purpose was to make a separation from the acronym and the
    letter "s," making it clear that the s was not part of the acronym. I
    still favor the capital acronym - lower case s, though.

    The interpretation that you mentioned makes some sense, but it
    reinforces the practice of tossing in an apostrophe when you
    don't know what else to do. And this dilutes the meaning of the
    punctuation. The guiding principle for my own writing is that
    when in doubt, I always aim for clarity. And when it comes to
    ambiguity, "head 'em off at the pass." In other words, shape the
    writing to ensure that ambiguity has been sucked out of the text.

    Whenever we use the apostrophe to pluralize a word, we put
    confusion into the reader's mind, and make the reader search the
    rest of the sentence or paragraph for the context in order to
    clarify the meaning. I believe that it's the job of the technical
    writer to deliver clear descriptions and clear instructions to
    the end user.

    Technical writing is the opposite of fiction -- fiction is an
    art, in which we (hopefully) encourage the readers to make
    connections within their own minds -- ambiguity can be a
    wonderful part of this process. And ambiguity is often an
    essential part of comedy -- where the comic spins a yarn
    involving a word, and suddenly changes the word's context, and
    therefore its meaning, to create the punch line.

    Technical writing is a craft, a craft in which the writer can be
    an artful practitioner. You know when you read good technical
    writing because you get a picture of the job at hand while
    reading it -- that sense of "I've got it!" Have I been clear
    about this?

    Another misuse of punctuation that's become rampant is quotes to
    set off something and make it important. You'll find this one
    most often in the supermarket, as in "Peaches" 39 cents.
    There's a vague history regarding this vagueness -- I recall the
    logo of The Delaware and Hudson, an American railroad, which
    signed itself "The D&H", probably from before 1900. The reason is
    lost in the fog of antiquity, where it probably made as much
    sense as it does now. Imagine if the badge on the back of the
    car, instead of saying Hyundai, said "Hyundai". It seems absurd,
    but that's what some people do when making their signs. You may
    notice that I've intentionally omitted some proper punctuation
    and changed the usual order of it, to be clear about punctuation
    itself. Like I said, there's an art to this craft.

    Here's an entertaining book by Lynn Truss about punctuation.

    I've heard the lady on the radio and I found what she had to say
    very interesting. She's from England, of course; when conversing
    with people on the internet, I've noticed that the misuse of the
    apostrophe is quite rampant in the UK. The book has a forward by
    Frank McCourt, whose American Irish English may be worth the
    price of the book all by itself.

    Here's a page about ensure, insure, and assure.

    I'll repeat the apostrophe web site addresses again:
