2007 Cadillac SRX Parts Questions & Experts Answers

• Q: How to properly replace the Engine Control Module (ECM) to prevent component damage and ensure accurate programming on 2007 Cadillac SRX?

  A: Before handling the ecm connectors for replacement of the Engine Control Module (ECM) always switch off the ignition to safeguard components from damage. It is essential to record the engine oil life length because failing to program this information in the replacement module will activate a default 100 percent requirement resulting in a 5,000 km (3,000 mi) maximum usage period from last change. Treatment of the automatic transmission fluid life follows the same pattern because no programming will result in a default setting of 100 percent which leads to a fluid change at 83,000 km (50,000 mi) from the last change. A scan tool must be used first to obtain percentages of engine oil and automatic transmission fluid remaining life which should then be recorded. The next step requires shutting off the ignition while disconnecting the battery negative cable. First elevate and support the vehicle before you can remove the front air deflector from its position. The electromechanical connections for ecm must disconnect first while you remove the ecm mounting nuts before you extract the ecm from the vehicle. The installation process begins by placing the ecm inside the vehicle and following with ecm mounting nuts installation at 8 n.m (71 lb in) tightness before reconnecting the ecm electrical connectors and reattaching the front air deflector. After vehicle elevation and battery negative cable reconnection you must program the ecm if required.
