CONTROL MODULE (PCM)

CAUTION:
As ECM (PCM) consists of precision parts, be careful not to
expose it to excessive shock.

Removal

1) Disconnect battery negative cable from battery.
2) Disable air bag system (if equipped) referring to “Disabling the

Air Bag System” in Air Bag System section.

3) Remove ECM (PCM) cover (1) from bracket.

4) Disconnect connectors from ECM (PCM).
5) Remove ECM (PCM) with bracket.

Installation

1) Install ECM (PCM) with bracket to vehicle.
2) Connect connectors to ECM (PCM) securely.
3) Install ECM (PCM) cover to bracket.
4) Enable air bag system (if equipped) referring to “Enabling Air

Bag System” in Air Bag system section.

5) Connect negative cable to battery.
