hello everybody this is my first post here, im using obdlink sx , i have pcm hammer 2 and universal patcher, im trying to do a vats removal on a 2002 3500 8.1l 4l80e for california calibration
original vin : 3GBKC34G62M103176
OSID: 12216125
description: p01 service number : 12200411
calibration: 12208511
hardware: 9386530
serial number: 1EB153TC1060
BROAD cast code: DLAC
MEC: 0
VOLTAGE: 12.5

at the beginning i could read the original bin file, i modified bin file with universal patcher for vats removal, when attempting to write full flash (clone) is not allowing me to write properly the new information
problems in 008000-01FFFF (calibration) and 006000-007FFF (parameter), i verified new bin file with vats removed and its says different but ok, now when im trying to re write with original bin file is not letting me do that, i cannot read the bin file now, i cannot even read the vin its says : '' VIN query failed: Timeout '' , i probably bricked the ecm some help will be appreciated to fix this issue and complete the vats removal.

these are the errors that is throwing me after attempting to correct the ecm, re writing with original bin and recover system: forgot to say is telling me these '' Operating system request failed, checking for a live kernel... ''
" [12:19:07:123] PCM is in recovery mode. "

i tried with a j2534 jvci+ autel and clone vcm2 i just dont have access with both, so with obdlink sx is retrying like 100 times and taking aprox 20 min and is still throwing errors, i will adjunct results , debug log, original read bin file, and modified file.

these readings where taken in an attempt to flash with a different file with different vin same osid found in a repository on gidhub similar 8.1l , same issue is throwing me with original bin file and vats removed file.

Code: Select all

Firstly PCM Hammer 2 is a preview release only. It is still under testing and you should only be using it if you can afford to loose a PCM and want to support us to test the next version. There are known problems with it (though that did not necessarily cause your problem). For general use, continue to use v021.

What you have is a partial brick. It is in recovery mode because the flash is corrupt but the boot sector is OK. PCM Hammer can recover from this assuming the bench and the power and the interface hardware etc is all good. You should try and do a clone write with the official 0.21 pcm hammer version and a known good bin file to get it back to normal.

thank you, i used pcm hammer 21v to recover the ecm , i could flash it and read now, i read it again and put the new reading bin file in universal patcher and is showing vats removed, it seems everything is working fine, i used same bin files that i uploaded here, i will test it now in the car, any news i will let you guys now, great job with pcm hammer

i used godiag gt100+ as bench , amps where between 0.21 a to 0.4 while flashing , source is 2 amps so its good for this application (intel chip), voltage keep between 12.5 and 12.9

obdlink sx is slow but i used in the past for saab ecm clonning so is trustworthy

one thing that is making me think is the calibration , this one has a california approved calibration 12208511 , but original calibration is 12216121 (4l80e) i hope new calibration is for the same kind of transmission , is there any way to check a list of calibrations for an specific transmission, engine size , number of axles and other characteristics? , like chrysler has a list of calibrations on fed word.pdf

i tried to check calibrations with free account on ac delco website using vin : 3gbkc34g62m103176 with no results there was not even 1 calibration

at the beginning before the flashing when i read the new ecm by obd there was a transmission related code and a vats code

Posted: **Thu Jun 19, 2025 9:54 am**

hello i already tested the ecm in the car and is starting and transmission working (at) , it has some check engine codes, i still have troubles with the calibrations, i would like to know what calibrations is for federal, california, efi , diesel, for number of axels, etc. for this 8.1l 2002, im sharing bin file of original ecm calibration with bad vin ( original calibration shows 12216121 ) :

You should be able to disable P1626 processing since you dont care that you didnt get the fuel enable signal with VATS off. P0706 might clear once it sees valid changes from the transmission range switch.
