Engine Control Module (ECM): Installation

  1. To install, reverse removal procedure. The power window control system (if equipped) and sun roof (if equipped) may need to be initialized for proper operation, due to the battery being disconnected.
  2. To re-initialize the power window control system, close any window to the highest position and hold window control switch in this position for 5 seconds. Check that power window automatic operation works properly. If power window automatic operation does not work properly, repeat the procedure.
  3. To re-initialize the sun roof, depress sun roof switch and operate sun roof to the maximum tilt position. Release sun roof switch. Depress and hold sun roof switch again. After 10 seconds, the sun roof will start automatic operation and complete one cycle (tilt downward, slide open, slide closed and tilt upward) while sun roof switch is depressed. DO NOT release sun roof switch until sun roof stops. Check that sun roof stops in correct position.
  4. Ensure ignition keys are registered to the ECM. See IGNITION KEY REGISTRATION  under PROGRAMMING.
