Installation Procedure
1. Slide the ECM into the retainer until the clips (1)
engage the ECM.
2. Grasp the ECM retainer and slide the retainer
forward until the retainer locks against the 4 clips on
the battery cover.
Engine Electrical Devices:
3. Connect the engine wiring harness electrical
connector (2) to the ECM.
4. Connect the negative battery cable. Refer to "Battery
Negative Cable Disconnection and Connection: ".
5. If a NEW ECM was installed, reprogram the ECM.
Refer to "Engine Control Module Programming and
Setup".
Engine Control Module Programming and
Setup
The following service procedures require either a
programming or a setup event performed for a complete
repair.
ECM Replacement
If the engine control module (ECM) is replaced, the
following procedures must be performed:
1. ECM Reprogramming—Refer to "Service
Programming System (SPS): ".
2. Idle Learn Procedure—Refer to "Idle Learn: " in
Engine Controls - 3.6L (LY7).
3. Theft Deterrent—Refer to "Theft Deterrent Control
Module Programming and Setup: ". The ECM will
learn the incoming fuel continue password
immediately upon receipt of a password message.
Once a password message is received, and a
password is learned, a learn procedure must be
performed to change this password again. An ECM
which has been previously installed in another
vehicle will have learned the other vehicle's fuel
continue password, and will require a learn
procedure after programming to learn the current
vehicle's password.
