DOOR LOCK CONTROL RELAY INSPECTION










1. INSPECT RELAY CIRCUIT
Disconnect the connector from the relay and inspect the connector on the wire harness side, as shown in the chart.

If circuit is as specified. inspect the door lock signal and key-off power window signal.

a. Connect the connector to the relay.
b. Connect the positive (+) lead from the voltmeter to terminal 1 and the negative (-) lead to terminal 6.
c. Set the door lock control switch to UNLOCK, check that the voltage rises from 0 V to battery positive voltage for approximately 0.2 seconds.







d. Reverse the polarity of the voltmeter leads.
e. Set the door lock control switch to LOCK, check that the voltage rises from 0 V to battery positive voltage for approximately 0.2 seconds.

If operation is not as specified, replace the relay.
