The service of powertrain control module (PCM) requires either pcm replacement or eeprom programming. You should use the accurate part for replacement which will require you to remove the damaged pcm before installing the new service pcm. The prevention of pcm internal damage requires the ignition switch to remain off during power connections and disconnects to the pcm, in addition to clearing all debris from around the pcm connectors. The pcm module connector gasket installation should be checked to avoid unwanted contaminant intrusion. After installation the new pcm needs to undergo programming procedures. A scan tool should be used first to obtain and document the current engine oil life percentage because absence of this data in the new module replacement will automatically reset the oil meter to 100% and trigger an oil change at 5000 km (3,000 mi). First disconnect the negative
Battery Cable then free the mounting tabs of the pcm cover before taking out the pcm cover. Disconnect the pcm electrical connector bolts while maintaining the off state of ignition to avoid harming internal components. Escort the pcm electrical connectors from the system then disengage both spring latch and mounting tabs before extracting the pcm from its position. The new pcm installation requires users to connect its electrical connectors while aligning the mounting tabs to engage the spring latch. The pcm electrical connector bolts should be tighted to 8 n.m (71 lb in) while installing the pcm cover with proper engagement of mounting tabs followed by negative Battery Cable connection and pcm programming when installing a new pcm.
