  2. Remove the fasteners retaining the throttle actuator control (TAC) module to the powertrain control module (PCM) mounting bracket.
    3. IMPORTANT:
    • Remove any debris from the 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.
  3. Remove the electrical connectors from the TAC module.
  4. Remove the TAC module from the vehicle.
