2008 Cadillac XLR Engine Control Module Parts and Q&A

• Q: What precautions should be taken during Engine Control Module service on 2008 Cadillac XLR?

  A: Engine control module (ecm) service requires ecm component replacement or eeprom programming and when replacement is needed check for the correct part selection. The process of installing and removing control module connectors together with power disconnects must always have the ignition set to off to safeguard the internal components from damage. Never let the metal case of the control module touch battery voltage during service since this will lead to damage. Guard against electrostatic damage by refraining from touching connector pins or soldered components of the circuit board and ensuring all dust and dirt is cleared from around the control module connector surfaces. An inspection of the control module connector gaskets will confirm their proper installation status to block contaminant access. Failure to record engine oil lifetime and automatic transmission fluid lifetime beforehand will cause default percentages to set engine oil change requirements at 5000 km (3,000 mi) and automatic transmission fluid requirements at 83000 km (50,000 mi) from the last change schedule. Begin by obtaining and writing down the remaining engine oil and automatic transmission fluid life with a scan tool before you take out the right front wheelhouse filler panel to disconnect the ecm electrical connectors and take off its fasteners. Installation requires users to place the ecm on the ecm bracket and fasten retaining fasteners to 3.0 N.m (27 lb in). Users must reconnect electrical connectors afterward then reinstall the right front wheelhouse filler panel. When installing a new ecm users must program it.
