How do i change the Electronic Computer Module (ECM) in a 1996 pontiac 2.2 automatic sunfire
I would get a second opinion , there not the brightest people . Take it to a ASE certified repair shop or dealer . Does your vehicle start an run ? If the brain box was bad it probably would not .
Powertrain Control Module/EEPROM Replacement/Programming
Powertrain Control Module (PCM)
Notice: In order to prevent internal damage to the PCM, the ignition must be OFF when disconnecting or reconnecting the PCM connector.
Service of the PCM should normally consist of either replacement of the PCM, EEPROM re-programming or a KS module change.
If the diagnostic procedures call for the PCM to be replaced, the PCM should be checked first to see if it is the correct part. If it is, remove the KS module from the faulty PCM and install it in the new service PCM. The service PCM will not contain a KS module. DTC P0601 indicates the EEPROM programming has malfunctioned. When DTC P0601 is obtained, re-program the EEPROM. If a DTC P0325 is set, check the KS module for proper installation. If it is installed correctly and DTC P0325 is still displayed, replace the KS module.
The ignition should be OFF for at least 10 seconds before disconnecting power to the PCM so the IAC valve has time to move to the engine OFF position.
