Universal Reprogrammer I
2000-2001 Cadillac Controllers - A communication error may occur at the end of the reprogram in the TIS software. If you receive this error once the progress bar goes to 100% you will not be able to reprogram this controller.
All 2004+ GM Controllers - A communication error may occur in the TIS 2000 software after you select a controller to be reprogrammed. To remedy this you need to name the J2534 profile in the TIS 2000 software "Generic Pass Thru" without the quotes.
2002 Chev. Trailblazer - ABS and LGM Fuses must be removed before reprogramming the PCM in this vehicle. The controller can be reflashed Off-Board without any problems.
1999-2003 Corvettes & Cadillacs - GM Requires that a Star Adapter be used during reprogramming the PCM in-vehicle. The controller can be reflashed Off-Board without any problems. Check any TSB's on the vehicle to be sure it requires the adapter.
1995-1997 Firebird LT1 - On some models, PIN 29 needs to be switched to PIN 30 on our cables to flash this vehicle. Check the wiring diagrams for your vehicle to make sure the pin outs are correct.
2007 Cadillac CTS - This vehicle is currently not supported by the Universal Reprogrammer I at this time.
2000-2004 Chevrolet Malibu/Impala/Monte Carlo BCM Replacement - If the B1001 error code remains in the the vehicle after completing the AirBag Serial Number relearn you will need to use the Tech 2 to perform the "New BCM Setup" procedure.
2004+ GM Single Wire CAN - The reprogramming of GM Single Wire CAN controllers is not supported by the Universal Reprogrammer I at this time. There are relatively few Radio and Body controllers that are Single Wire CAN. All Powertrain controllers are supported.
Universal Reprogrammer II
Please make sure your Universal Reprogrammer II is up to date with the latest Driver and Firmware.
Universal Reprogrammer Both I & II
Do not swap used control modules on the following vehicles they must be new controllers only from GM. Also GM will be introducing more models to this new system. Please check with GM Support line (1-888-212-8959) if you are not sure the vehicle you are working on has Global Architecture. This new system started in 2010.
The Global Architecture electrical system does not allow control modules to be swapped between vehicles. Swapping control modules will result in a no start condition on the vehicle and will damage modules due to the new vehicle Global Architecture System.
These models have this system now:
- 2010-2015 LaCrosse
- 2011-2015 Regal
- 2012-2015 Verano
- 2013-2015 Encore
- 2010-2015 SRX
- 2013-2015 ATS, XTS
- 2014-2015 CTS Sedan, ELR
- 2015 Escalade Models
- 2010-2015 Camaro, Equinox
- 2011-2015 Cruze
- 2012-2015 Sonic, Volt
- 2013-2015 Spark, Trax (Canada only)
- 2014 Silverado 1500, Spark BEV
- 2014-2015 Caprice PPV, Corvette, Impala, SS
- 2015 Colorado, Silverado, Suburban, Tahoe
- 2010-2015 Terrain
- 2014 Sierra 1500
- 2015 Canyon, Sierra, Yukon Models
These are the controller that can't be swap on the list above:
- Engine Control Module (ECM)
- Body Control Module (BCM)
- Electronic Brake Control Module (EBCM)
- Sensing and Diagnostic Module (SDM)
- Transmission Control Module (TCM)
- Electronic Climate Control (HVAC)
- Electric Power Steering
- Hybrid Powertrain Control Module
- Vehicle Communication Interface Module
- Instrument Panel Cluster
Warning reflashing: This procedure is for the following vehicles (2002-early 2006 Trailblazer, Bravada, and Envoy).
Re-flashing the PCM without disconnecting all other modules typically ends with a failed flash and a new controller being needed.
To prevent this from happening:
Aftermarket Radios and Accessories: On pre-CAN 2005/2006 and previous vehicles can cause reflashing failures. Make sure to remove any aftermarket accessory that may be connected to the vehicle data lines.
- Remove the SP205 splice pack (drivers side kick panel)
- Jump terminals A & B (PCM to DLC)
- Replace the splice connector after programming is complete.
Pre-CAN GM vehicles: If the reflash fails keep the vehicle key in the "On" position. Consult information sources again to see if a procedure was missed. The controller maybe recoverable if left in the “On” position. If the key is turned off the controller will most likely be non-functional.
