  Q: How to replace the ABS Control Module on Buick Terraza?

  A: The first step when replacing the ABS Control Module is to put the ignition switch in the off position to prevent harm to the ABS Control Module. The first step requires extraction of the air cleaner assembly from the engine compartment followed by harness connector removal from the ABS Control Module unit while wiping off all accumulated dirt and debris. It is essential to disconnect the pump motor connector from the ABS Control Module base but be aware of avoiding damage while removing the solenoid valves and seal. Start by removing the screws which attach the ABS Control Module to the brake pressure modulator valve (BPMV). After that pull the ABS Control Module away from the bpmv with slight force until they separate. The bpmv requires a clean alcohol treatment using a fresh rag prior to ABS Control Module installation. Start with the ABS Control Module attachment to the bpmv by inserting six screws followed by tightening the top four screws to 5 n.m (44 lb in) in an x pattern while the bottom two screws receive the same torque of 5 n.m (44 lb in). First reconnect the bottom ABS Control Module pump motor connector followed by the ABS Control Module electrical harness connector at its top and install the air cleaner assembly. Installation of a new ABS Control Module requires programming according to the process. To complete the check first place the ignition switch at run position without starting the engine.
