Communication Between Immobilizer and Test Equipment

1. Connect the test equipment as described in the Scan Tool Equipment Manual.
2. If communication between the scan tool and the test equipment is unsuccessful, wait 30 seconds and try again.
3. If communication is not successful on the second try, turn the ignition OFF, and check the wire and the connectors between the immobilizer control unit terminal 3 and the data link connector (DLC).
4. If the wire and the connectors between the DLC and the immobilizer control unit are OK, replace the immobilizer control unit.
