Powertrain Control Module Programming

WARNING: This page is about a different car, the 2002 Pontiac Sunfire, 2002 Chevrolet Cavalier, 2001 Pontiac Sunfire, and 2001 Chevrolet Cavalier. However, it is still accessible from the selected car via links, so may be relevant.

WARNING: If Powertrain Control Module (PCM) was replaced, EEPROM in PCM must be programmed. If EEPROM is not programmed, a Diagnostic Trouble Code (DTC) will be set in PCM, or PCM may be damaged.

Powertrain Control Module (PCM) can only be programmed using pass-through programming method. Pass-through programming method requires use of a scan tool in series with Techline(R) terminal and Data Link Connector (DLC). Perform EEPROM programming using Techline equipment manufacturer's instructions and latest software applicable for vehicle model.

Once EEPROM is reprogrammed, Crankshaft Position (CKP) sensor variation learn procedure must be performed using proper procedure.
