Installation Procedure
- With the ignition off, position the ECM to the ECM bracket.
- Install the nuts securing the ECM to the ECM bracket.
Tighten: Tighten the ECM nuts to 8 N.m (71 lb in).
- Carefully align the harness connectors (2) with the ECM connectors.
- Guide the connectors (2) into place while moving the release levers to the locked position (1).
- Install the screw (2) securing the ECM ground wire (1) to the ECM (3).
Tighten: Tighten the ECM ground wire screw to 4.5 N.m (40 lb in).
- Program the ECM. Refer to Service Programming System (SPS) in Programming.
- Program the theft deterrent system components if the ECM was installed from another vehicle. Refer to Programming Theft Deterrent System Components in Theft Deterrent.
- Perform the idle learn procedure. Refer to Idle Learn Procedure .
NOTE:
Refer to Fastener Notice
in Cautions and Notices.
IMPORTANT:
When replacing a ECM with a GM SPO Replacement Part, the new ECM will learn the incoming fuel continue password immediately after programming and upon receipt of a password message. Once a password message is received and a password is learned, perform the learn procedure to change this password again. A ECM which had been installed in another vehicle will have learned the fuel continue password of the other vehicle's theft deterrent control module. Perform either the 10-minute relearn procedure or the 30-minute relearn procedure after programming to learn the fuel continue password of the current vehicle's theft deterrent control modules.
