2005 Chevrolet Malibu Parts Questions & Experts Answers

• Q: How to replace the Engine Control Module (ECM) on 2005 Chevrolet Malibu?

  A: First use a scan tool to retrieve engine oil life percentage data during the pcm replacement process because failure to program this data into the new module will result in default parameters causing an immediate 5000 km (3,000 mi) interval for the next oil change after the previous one. After recording the preset radio stations one should first turn off the ignition and disconnect the negative Battery Cable before disconnecting the pcm harness connectors. Use a suitable tool to open the retaining tab on the lower portion of the battery box then lift up and remove the pcm after freeing the tab. The installation requires you to insert the pcm bracket onto the battery box front then push down until the retaining tab snaps into position. After connecting the pcm harness connectors and the negative Battery Cable maintain torque on the battery terminal bolts to 17 n.m (13 lb ft). To perform misfire diagnostics programming initiate the pcm programming followed by conducting a Crankshaft relearn procedure because the pcm requires learning the position variation of the Crankshaft. Finally, reset the clock and preset radio stations.
