Removal Procedure

WARNING: This page is about a different car, the 2004 Cadillac CTS. However, it is still accessible from the selected car via links, so may be relevant.
  1. Disconnect the battery negative cable. Refer to Battery Negative Cable Disconnect/Connect Procedure in Engine Electrical.
    2. IMPORTANT:
    • Remove any debris from the throttle actuator control (TAC) module connector surfaces before servicing the TAC module. Inspect the TAC module connector gaskets if you diagnose or replace the TAC module. Verify that the gaskets are installed correctly. The gaskets prevent contaminate intrusion into the TAC module.
    • Do not touch the connector pins in order to prevent possible electrostatic discharge (ESD) damage to the TAC module.
    • The ignition should always be OFF if you install or remove the TAC module connectors.
