1.CHECK FUNCTION
With CONSULT-III
Check CDL LOCK SW, CDL UNLOCK SW in Data Monitor mode with CONSULT-III.
Is the inspection result normal?
YES >> Door lock and unlock switch is OK.
NO >> Refer to DLK-74, "
DRIVER SIDE : Diagnosis Procedure".
DRIVER SIDE : Diagnosis ProcedureINFOID:0000000005146931
Regarding Wiring Diagram information, refer to DLK-157, "Wiring Diagram — POWER DOOR LOCK SYS-
TEM —".
1.CHECK DOOR LOCK/UNLOCK SWITCH INPUT SIGNAL
With CONSULT-III
Check main power window and door lock/unlock switch ("CDL LOCK SW", "CDL UNLOCK SW") in DATA
MONITOR mode in CONSULT–III.
• When main power window and door lock/unlock switch is turned to LOCK:
• When main power window and door lock/unlock switch is turned to UNLOCK:
Without CONSULT-III
1. Remove key from ignition key cylinder.
2. Using an oscilloscope, check the signal between BCM connector M18 terminal 22 and ground when the main power window and door lock/unlock switch is turned to LOCK or UNLOCK.
3. Make sure the signals which are shown in the figur e below can be detected during 10 seconds just after
the door lock/unlock switch is turned to LOCK or UNLOCK.
