How to replace the Engine Control Module safely and effectively on Chevrolet Silverado 3500?

A powered-up ignition should always be switched off before beginning to work on the powertrain control module (PCM). This ensures the pcm remains undamaged during power disconnection or reconnection. Remove all debris from around pcm connector surfaces before checking the installation of pcm module connector gaskets to avoid contaminant access. A scan tool allows you to retrieve engine oil life percentages which must be recorded before the replacement module installation because not programming this data will trigger a 100% default that requires an oil change within 5000 km (3,000 mi) of the last change. To begin the procedure disconnect the negative Battery Cable along with removing the harness ground clip from pcm cover when rpo nos exists. The hybrid control module (HCM) needs removal when dealing with vehicles equipped with rpo hp2. Unfasten the pcm cover mounting tabs and detach the pcm cover from its place. When disabling the electrical connectors from the pcm use care not to allow the ignition to be on while working because this could harm components. Disengage the spring latch and mounting tabs attached to the pcm before extracting the pcm from its place. The installation process requires you to enter the mounting tabs and fasten the spring latch onto the new pcm. After attaching the pcm electrical connectors install the bolts just to 8 n.m (71 lb in). Install the pcm cover along with reattaching the hcm when your vehicle has rpo hp2 and continue if your vehicle lacks this reference. Users of rpo nys should connect the harness ground clip to the pcm cover and reinstall the negative Battery Cable before pcm programming if needed.
