Programmed 1999-2000 Sierra 1500 PCM 16263494 | VIN Flashed ECU

There were no consistent trouble codes, just a history of random communication errors. After verifying the wiring harness and grounds were solid, my gut pointed to the PCM. The internal processors on these units can develop micro-fractures over years of heat cycles, causing unpredictable behavior.

Other info: Why buy your spare PCM from us? You will be purchasing a high quality used PCM. You get free Flash programming with every OBDII GM computer purchased. OBDII type computers have the “chip” imbedded into the PCM and it is not removable. The calibration file per the application is “Flashed,” or reprogrammed using a software package and a pass through device. The “chip” is no longer removed for programming. Proper programming is essential when replacing a PCM whether it is a used PCM or a remanufactured PCM. A used GM computer will have the software installed that pertains to the original vehicle that it was removed from. In some cases, GM OBDII type computers will interchange with many different vehicles including those with different engine and transmission configurations. However, unless the computer is programmed with the correct software it won’t function properly upon installation. We will flash program the computer purchased from us with your specific VIN number for the latest updated calibrations available for a stock calibration. This is important to ensure specific vehicle programming and to guarantee flawless performance in your vehicle. At the end of the auction you will need to provide us with your VIN (Vehicle Identification Number). ******View our e-bay store for more pcm’s.
