INFOID:0000000009461835
1.CHECK FUNCTION
With CONSULT
Check CDL LOCK SW, CDL UNLOCK SW in Data Monitor mode with CONSULT.
Is the inspection result normal?
YES >> Door lock and unlock switch is OK.
NO >> With LH and RH anti-pinch, refer to DLK-106, "PASSENGER SIDE : Diagnosis Procedure (With
LH and RH Anti-Pinch)".
NO >> With LH anti-pinch only, refer to DLK-107, "PASSENGER SIDE : Diagnosis Procedure (With LH
Anti-Pinch Only)".
PASSENGER SIDE : Diagnosis Procedure (With LH and RH Anti-Pinch)INFOID:0000000009461836
Regarding Wiring Diagram information, refer to DLK-51, "Wiring Diagram".
1.CHECK POWER WINDOW SWITCH OUTPUT SIGNAL
1. Read voltage signal between BCM connector and ground with oscilloscope when power window and door lock/unlock switch RH is changed to “LOCK” or “UNLOCK”.
2. Check that signals which are shown in the figure below can be detected during 10 second just after power
window and door lock/unlock switch RH is changed “LOCK” or “UNLOCK”.
Is the inspection result normal?
YES >> GO TO 4
NO >> GO TO 2
2.CHECK POWER WINDOW SWITCH GROUND
1. Turn ignition switch OFF.
2. Disconnect power window and door lock/unlock switch RH connector.
3. Check continuity between power window and door lock/unlock switch RH connector and ground.
