Component Tests and General Diagnostics

INSPECTION







1. Master switch
INSPECT DRIVER'S DOOR LOCK CONTROL SWITCH CONTINUITY
If continuity is not as specified, replace the switch.







2. INSPECT PASSENGER'S DOOR LOCK CONTROL SWITCH CONTINUITY
If continuity is not as specified, replace the switch.







3. INSPECT DOOR KEY LOCK AND UNLOCK SWITCH CONTINUITY
If continuity is not as specified, replace the switch.







4. INSPECT DOOR UNLOCK DETECTION SWITCH CONTINUITY
If continuity is not as specified, replace the switch.

5. INSPECT DOOR KEY LOCK MOTOR OPERATION




a. Connect the positive (+) lead from the battery to terminal 3 and the negative (-) lead to terminal 2, and check that the door lock link moves to UNLOCK position.




b. Reverse the polarity and check that the door lock link moves to LOCK position.
If operation is not as specified, replace the door lock assembly.




6. Door lock signal
INSPECT DOOR LOCK CONTROL OPERATION
a. Disconnect the connector from the junction block No.1.
b. Connect the positive (+) lead from the voltmeter to terminal 9 and the negative (-) lead to terminal 8.
c. Set the door lock control switch to UNLOCK, check that the voltage rises from 0 V to battery positive voltage for approximately 0.25 seconds.
d. Remove the polarity to 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 0.25 seconds.







7. w/ Daytime running light:
CHECK INTEGRATION RELAY (DRIVER SIDE JUNCTION BLOCK) CIRCUIT
a. Disconnect the 1H, 1I, 1J, 1K and 1N driver side junction block connectors, and check the voltage or continuity of each terminal of the wire harness side connectors.
If the result is not as specified, there may be a malfunction on the wire harness side.
If the result is not as specified, the integration relay (junction block) may malfunction




b. Reconnect the 1H, 1I,1J, 1K and 1N junction block connectors, and check the voltage of each terminal of the connectors.
If the result is not as specified, the integration relay (junction block) may malfunction







c. Remove the integration relay from the driver side junction block, and check the voltage or continuity on each terminal of the junction block side.
If the result is not as specified, replace the driver side junction block.







8. w/o Daytime running light:
CHECK INTEGRATION RELAY (DRIVER SIDE JUNCTION BLOCK) CIRCUIT
a. Disconnect the 1H, 1I, 1K, 1J and 1L driver side junction block connectors, and check the voltage or continuity of each terminal of the wire harness side connectors.
If the result is not as specified, there may be a malfunction on the wire harness side.
If the result is not as specified, the integration relay junction block) may malfunction.




b. Reconnect the 1H, 1I, 1K, 1J and 1N junction block connectors, and check the voltage of each terminal of the connectors
If the result is not as specified, the integration relay junction block) may malfunction.




c. Remove the integration relay from the driver side junction block, and check the voltage or continuity of each terminal on the junction block side.
