2005 Cadillac XLR Parts Questions & Experts Answers

• Q: What precautions should be taken during Engine Control Module service and what does it typically involve on 2005 Cadillac XLR?

  A: The service of Engine Control Module (ECM) requires either new ecm components or eeprom programming sessions yet requires confirmation of part correctness before starting either procedure. Internal ecm damage can be avoided by keeping the ignition off during every power transition during the component replacement process that involves disconnecting or reconnecting the Battery Cable and ecm pigtail and ecm Fuse and jumper cables. The gasket service of ecm module connector requires debris removal from ecm connector surfaces and proper gasket installation to stop any intrusion. The service programming system (SPS) should be used to program the new ecm. You must start the removal process by obtaining the engine oil and automatic transmission fluid life percentages using a scan tool since omitting this step will default to 100% that triggers immediate engine oil change after 5000 km (3,000 mi) and automatic transmission fluid change at 83000 km (50,000 mi) from the last maintenance. Start by taking out the right front wheelhouse filler panel then detach the ecm electrical connectors before uninstalling the fasteners which secure the ecm. Secure the ecm to its ecm bracket through retaining fasteners that should be tightened to 3.0 n.m (27 lb in). Install the electrical connectors into the ecm before putting back the right front wheelhouse filler panel while ecm programming requires new ecm installation.
