Power Door Lock Relay: Testing and Inspection

INSPECT DOOR LOCK CONTROL RELAY CIRCUIT
Disconnect the connector from the door lock control 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.




Driver's door lock signal:
INSPECT DOOR LOCK CONTROL RELAY OPERATION

HINT: When the relay circuit is as specified, inspect the door lock signal.

a. Connect the positive (+) lead from the voltmeter to terminal 2 and the negative (-) lead to terminal 1.
b. Set the door lock control switch to UNLOCK and check that the voltage rises from 0 V to battery positive voltage for approximately 0.2 seconds.




c. Reverse the polarity of the voltmeter leads.
d. Set the door lock control switch to LOCK and 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.
