DeVille DHS V8-4.6L VIN Y (2000)
Powertrain Control Module: Service and Repair
REMOVAL PROCEDURE
1. Record the Transaxle Fluid and Engine Oil Life Indexes.
IMPORTANT: The key must be in the LOCK/OFF position for a minimum of 30 seconds prior to disconnecting power to the PCM. This allows the
PCM to store the vehicle information into the EEPROM. Failure to wait the 30 seconds may result in a EEPROM reset and the fluid life indexes being
reset to 0.
2. Disconnect the negative battery cable.
3. Remove the screw retaining the intake air duct/resonator to the PCM housing.
4. Unsnap the air filter housing clamps on top of the air cleaner housing assembly.
5. Pull the intake air duct/resonator assembly (2) up enough to remove the air cleaner cover (3) and the PCM.
6. Slide the air cleaner element assembly toward the fender to separate the air cleaner element assembly from the air inlet assembly.
