2007 Cadillac XLR Parts Questions & Experts Answers

• Q: What precautions should be taken during Engine Control Module service, and what does it typically involve on 2007 Cadillac XLR?

  A: Ecm service requires customers to choose between new ecm component installation or eeprom data programming. Check that the replacement option matches the right part before conducting ecm replacement. The procedure requires the ignition to be off during all control module connector operations and every instance of power connection and disconnection to the control module components including Battery Cable and pcm connections and ecm connections and tcm connections and control module fuse and jumper cables to stop control module internal damage. Maintenance should exclude any contact between the control module metal case and battery voltage while servicing operations including battery booster usage and charging procedures. Touching either the circuit board connector pins or soldered components will cause electrostatic discharge damage so avoid this practice alongside removing debris from control module connector surfaces. The control module connector gaskets should be checked for correct installation because improper installation allows contaminants to enter the system. A replacement control module requires programming but failure to note engine oil lifetime and automatic transmission fluid lifetime will cause default values to trigger oil changes at 5000 km (3,000 mi) and transmission fluid changes at 83000 km (50,000 mi) from the last service dates. Start by using a scan tool to get the oil life data and fluid life data which then allows the removal of right front wheelhouse filler panel to disconnect the harness connectors before ecm fasteners are taken out. Installation requires the ecm to be mounted onto the ecm bracket before users fasten the ecm retaining fasteners to 3.0 n.m (27 lb in) then connect electrical connectors to the ecm followed by right front wheelhouse filler panel reinstallation. The installation of new ecms requires programming.
