Diagnosis Procedure
1.CHECK CONNECTOR
Turn the ignition switch OFF.
Disconnect the battery cable from the negative terminal.
Check the terminals and connectors of the BCM for damage, bend and loose connection (unit side and connector side).
2.CHECK HARNESS FOR OPEN CIRCUIT
Disconnect the connector of BCM.
Check the resistance between the BCM harness connector terminals.

3.CHECK POWER SUPPLY AND GROUND CIRCUIT
Check the power supply and the ground circuit of the BCM. Refer to BCS-36, "Diagnosis Procedure".
