2008 Chevrolet Corvette Parts Questions & Experts Answers

• Q: What does Engine Control Module service typically involve, and what precautions should be taken during Engine Control Module replacement or EEPROM programming on 2008 Chevrolet Corvette?

  A: Engine Control Module (ECM) service mainly consists of ecm substitution together with eeprom programming. Verification of the correct part should take place before executing an ecm replacement. Internal ecm damage can be avoided by making sure the ignition switch stays off throughout power disconnection and reconnection operations involving the Battery Cable as well as the ecm pigtail and ecm Fuse and jumper cables. The ecm connector surfaces need to be cleaned from debris while gaskets must be inserted correctly to stop intrusions. The new ecm needs its software programming to be completed. Representative engine oil life values must be recorded since such information failure to program into the new module defaults to 100 percent oil life resulting in forced 5,000 km (3,000 mi) oil change since the previous maintenance. A scan tool should be used to obtain the engine oil residual percentage which needs recording. To remove the ecm begin by removing the wheelhouse filler panel followed by engine wiring harness electrical connector disconnection from the ecm and finally taking out the ecm bolts . Place the ecm in position while tightening its ecm bolts to 10 n.m (89 lb in). After reattaching the engine wiring harness electrical connectors to the ecm you should reinstall the wheelhouse filler panel. Install a new ecm only when programming the control module according to its references becomes necessary.
