    TIME TO STOP FOD & ISOLATE ABILITY TO COM



    Okay now no one can whine I don't have a WD when I say JPPSG and go find pins and manually connect with ECU.

    WARNING!

    Do not just change parts or controllers due to a DTC or being burned up!

    Verify circuit tracks and why a burn down happened!

    Widespread misdiagnosed problems with controllers not being needed & for negated wire testing or repairs on LIN or PWM & due to wiring being insufficient in size or inadequate shield.

    Time to sharpen your pencil & because places are going to steal your money and compound your problems for inability to do proper repairs or transfers with inoperable vehicles!

    Shielding and ground plus ability to attenuate signals over a wire are very important!

    Verify critical wires are sufficient in diameter and can carry current or signals through connection T points.

    NostraJackASS Has Spoken!

    MERRY XMAS!

    Good reading!

    VOLUME AND PRESSURE ARE NOT THE SAME!



    I have been pointing to these two videos for many years.

    I strongly suggest you watch them and relate them to any fluid mechanics in anything!







    Funny story this last weekend.
    Recent posts are amusing me & disturbing me at same time how much basics are lacking.

    That good old "Pressure versus Volume" & I'm always running my mouth about in aforementioned videos.

    How does it affect fuel systems though?

    https://forums.ross-tech.com/showthr...h-idle-misfire

    Can a car appear to run rich while being lean as a result?

    Can a car run lean while appearing too operate rich as a result?

    Can air leaks or sensors cause it or controllers?


    Indeed it can....... the answer is yes to ALL!

    Have a life long friend that called about a month ago, there are not too many that exist in this category!

    He did all his basic tests, however, was missing something and he said he changed about everything under hood, now done listening to idiots.
    Car starts runs smooth than seconds later goes to misfire and dumping fuel, no codes!

    Now mind you this friend is not a dummy and knows what is what for most part.

    He was extremely frustrated, even when I'm asking him questions, than replying with saying I'm thinking of changing the entire engine, I've already done everything or having programmed with code to ignore it.
    I replied don't do that!, let me know when you want me to come by.

    He was so frustrated by even me asking questions, "did you check this or that" & because he really did already change or checked it, .....he went dark.
    I left him with some ideas, however, he indeed dismissed the volume test.

    He dismissed this test because he was sure he had PSI from fuel pump on gauge and he even changed it, in addition to regulator + tests.
    Well a few weeks later he changed the entire engine + other parts including, injectors, ECU & now it was driving him to a beyond defeated stance.
    I called and said so what was the solution? He was like man I changed the whole motor and it still does it!

    So I said let me come over and bring a bag and go over step by step and we will find it together.

    Car ran rich pig rich & filled the sump rich.....misfire like crazy, than reported literally no data on either OXS or no DTC's. ( The no DTC's was killing him on this car )

    Car would barely make it out of driveway no power down road bla bla.....

    He is like can't be a fuel PSI problem we have tons of gas or so it would seem I changed everything! "Nope Changed it" Dismissed!

    So we hook up with his scanner, OMG so FFFFFing slow compared to VCDS. We start with the decade box checking the reactions of the sensors in ECU blocks & to verify harness.
    We use a tone generator to track stuff quick & since we are in the field not in a shop, however, at least under a shade tree. Yeah I was sneezing from allergies & no AC, OMG not my fun work environment other than company,..... was well worth it, so I stuck it out, anyone that is truly my friend knows I'd die for them.

    We back trace OXS and verify that harness isn't grounded making some anomaly for full rich fuel dump, nope all good and he drops the cat to down pipe at same time to check for plugged cat, nope good!
    So I said hey I have an idea lets unplug the MAP sensor and plug it into one not in intake & so it doesn't see vacuum to force a condition in ECU.

    Note: this is a field test I developed many years ago and works very well outside the scope of RTFB!

    ( Unplugging a map sensor from vacuum port and covering hole or plugging in a spare map sensor.
    This is sometimes a great method of matching the BARO in ECU blocks and it permits a car that has inadequate delivery to usually run at idle to surmise a volume condition!)

    ( CRIMPING A FUEL LINE HOT & ENGINE RUNNING SHOULD NEVER BE DONE WITHOUT EXTREME SAFETY MEASURES IN PLACE IF NOT EVER! )


    It starts and idles perfect even after a minute just wont take a throttle and rightfully so, however, trims pop up and so does OXS!
    We cross check the map sensors they are all fine.

    We wait for adaption and trims they eventually go red lean......still no DTC's.....?
    I'm like here we go we have a volume issue, so did you know I convinced him to crimp the return fuel line & while running to see if we get a change and plug the map sensor on intake? Did you know it revs right up no miss no issues other than trims still red so now have to get other fuel pump?


    Further investigation resulted in possible additional FOD TBD!

    Triple FOD match ...... The vehicle can have 3 different fuel pumps, all look the same and each with a different volume output 190 LPH, another at 250 LPH and yet another at 350 LPH!

    VOLUME AND PRESSURE ARE NOT THE SAME!

    OBD DATA SHOULD NEVER BE TRUSTED EVER AND UNTIL UNLESS MECHANICAL/ELECTRICAL TESTS HAVE QUALIFIED IT!






    SECOND NOTE:

    JUST IMAGINE THE SITUATION IF HE WOULD OF PROGRAMMED WITH NEFARIOUS CODE TO IGNORE A PARAMETER!

    WHY A CVN AND CAL ID MATTER IN ADDITION TO TUNERS USING VIN NUMBER TO LOCK THEIR STUFF OR VIN ALTERING IN GENERAL
    https://govt.westlaw.com/calregs/Doc...8sc.Default%29


    (4.6) Software Calibration Identification


    (4.6.1) On all vehicles, a software calibration identification number (CAL ID) for the diagnostic or emission critical powertrain control unit(s) shall be made available through the standardized data link connector in accordance with the SAE J1979 specifications. Except as provided for in section (g)(4.6.3), for 2009 and subsequent model year vehicles, the OBD II system shall use a single software calibration identification number (CAL ID) for each diagnostic or emission critical powertrain control unit(s) that replies to a generic scan tool with a unique module address.


    (4.6.2) A unique CAL ID shall be used for every emission-related calibration and/or software set having at least one bit of different data from any other emission-related calibration and/or software set. Control units coded with multiple emission or diagnostic calibrations and/or software sets shall indicate a unique CAL ID for each variant in a manner that enables an off-board device to determine which variant is being used by the vehicle. Control units that utilize a strategy that will result in MIL illumination if the incorrect variant is used (e.g., control units that contain variants for manual and automatic transmissions but will illuminate the MIL if the variant selected does not match the type of transmission on the vehicle) are not required to use unique CAL IDs.


    (4.6.3) For 2009 and subsequent model year vehicles, manufacturers may request Executive Officer approval to respond with more than one CAL ID per diagnostic or emission critical powertrain control unit. Executive Officer approval of the request shall be based on the method used by the manufacturer to ensure each control unit will respond to a SAE J1978 scan tool with the CAL IDs in order of highest to lowest priority with regards to areas of the software most critical to emission and OBD II system performance.


    (4.7) Software Calibration Verification Number


    (4.7.1) All 20052 and subsequent model year vehicles shall use an algorithm to calculate a calibration verification number (CVN) that verifies the on-board computer software integrity in diagnostic or emission critical powertrain control units. The CVN shall be made available through the standardized data link connector in accordance with the SAE J1979 specifications. The CVN shall be capable of being used to determine if the emission-related software and/or calibration data are valid and applicable for that vehicle and CAL ID. For 50 percent of 2010 and 100 percent of 2011 and subsequent model year vehicles, one CVN shall be made available for each CAL ID made available and each CVN shall be output to a generic scan tool in the same order as the CAL IDs are output to the scan tool to allow the scan tool to match each CVN to the corresponding CAL ID.


    (4.7.2) Manufacturers shall request Executive Officer approval of the algorithm used to calculate the CVN. Executive Officer approval of the algorithm shall be based on the complexity of the algorithm and the difficulty in achieving the same CVN with modified calibration values.


    (4.7.3) The CVN shall be calculated at least once per driving cycle and stored until the CVN is subsequently updated. The stored CVN value may not be erased when fault memory is erased by a generic scan tool in accordance with SAE J1979 specifications or during normal vehicle shut down (i.e., key off, engine off).


    (4.7.4) When a CVN request message is received by the on-board computer, the stored CVN value shall be made available through the data link connector to a generic scan tool.

    (A) Except as provided below in sections (g)(4.7.4)(B) and (C), when a CVN request is received, the on-board computer may not respond with negative response codes (i.e., may not use delayed timing in sending the CVN and may not respond with a message indicating the CVN value is not currently available) and may not respond with a default value. Default value is defined as any value or space holder that is not a valid CVN value.


    (B) If the CVN request message is received within the first 120 seconds of vehicle operation after a reprogramming event or a non-volatile memory clear or within the first 120 seconds of vehicle operation after a volatile memory clear or battery disconnect, the on-board computer may respond with a negative response code directing the scan tool to wait or resend the request message after the delay. Such responses and delays shall conform to the specifications for transmitting CVN data contained in SAE J1979.


    (C) If a communication malfunction is preventing access to a CVN value for reporting in response to a scan tool request, a default CVN value may be reported in lieu of a valid CVN value provided that:

    (i) a pending fault code is stored or a confirmed fault code is stored with the MIL commanded on pinpointing a communication fault for the module that is unable to report a valid CVN, and


    (ii) the default CVN value used cannot be mistaken for a valid CVN (e.g., all zeros or all question marks for the default value).




    (4.7.5) For purposes of Inspection and Maintenance (I/M) testing, manufacturers shall make the CVN and CAL ID combination information available for all 2008 and subsequent model year vehicles in a standardized electronic format that allows for off-board verification that the CVN is valid and appropriate for a specific vehicle and CAL ID. The manufacturer shall use the most recent standardized electronic format detailed in Attachment E: CAL ID and CVN Data of ARB Mail-Out #MSC 06-23, December 21, 2006, incorporated by reference. Manufacturers shall submit the CVN and CAL ID information to the Executive Officer not more than 25 days after the close of a calendar quarter.


    (4.8) Vehicle Identification Number:


    (4.8.1) All 2005 and subsequent model year vehicles shall have the vehicle identification number (VIN) available in a standardized format through the standardized data link connector in accordance with SAE J1979 specifications. Only one electronic control unit per vehicle shall report the VIN to an SAE J1978 scan tool.


    (4.8.2) If the VIN is reprogrammable:

    (A) For 2012 and subsequent model year vehicles not included in the phase-in specified in section (g)(4.8.2)(B) below, all emission-related diagnostic information (i.e., all information required to be erased in accordance with SAE J1979 specifications when a Mode/Service $04 clear/reset emission-related diagnostic information command is received) shall be erased in conjunction with the reprogramming of the VIN.


    (B) For 30 percent of 2019, 60 percent of 2020, and 100 percent of 2021 and subsequent model year vehicles, if the VIN is reprogrammable, in conjunction with reprogramming of the VIN, the OBD II system shall erase all emission-related diagnostic information identified in section (g)(4.10.1) in all control modules that reported supported readiness for a readiness bit other than the comprehensive components readiness bit.
