Electronic Throttle Control Module: Service and Repair

THROTTLE ACTUATOR CONTROL (TAC) MODULE REPLACEMENT

REMOVAL PROCEDURE




1. Disconnect the battery negative cable.

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.

1. Remove the electrical connectors from the TAC module (1, 2).
2. Remove the TAC module from the locking tabs on the relay center bracket.
3. Remove the module from the vehicle.

INSTALLATION PROCEDURE




1. Install the TAC module to the vehicle.
2. Ensure that the module engages with the locking tabs on the relay center bracket.
3. Install the electrical connectors to the TAC module (1, 2).
4. Connect the battery negative cable.
