How to replace the Engine Control Module (ECM) on Buick Rendezvous?

The first step to replace a powertrain control module (PCM) requires verifying that the pcm you received is the correct one through inspection. The existing pcm must be replaced with the new service pcm though programming is mandatory since the replacement will not carry pre-written software. The dtc p0602 issue occurs when eeprom is unprogrammed or showing malfunction symptoms. The service pcm must receive its broadcast code and production pcm number during identification procedures until the end of its service life so one should skip covering these values on the pcm face. Begin by scanning for current engine oil life data using an official tool which should be recorded before replacement when replacement programming is omitted because the default engine oil life will set to 100% leading to an early oil-change requirement at 5000 km (3,000 mi). To extract the pcm from its assembly the technician must first disconnect the negative Battery Cable before removing the left sheet metal diagonal brace with air cleaner assembly cover followed by lifting the pcm. Connectors should be unmated from the pcm before taking it outside of the engine compartment. Begin by attaching the pcm electrical connectors while tightening their screws to 8 n.m (71 lb in) before placing the pcm inside the air cleaner assembly and covering it with retainers. Reinstall the left sheet metal diagonal brace next to the installation of the negative Battery Cable connection. The eeprom programming needs to be completed by any new pcm installation.
