Is the inspection result normal?
YES - Door lock and unlock switch is OK.
NO - With LH and RH anti-pinch, SEE Diagnosis Procedure (With LH and RH Anti-Pinch).
NO - With LH anti-pinch only, SEE Diagnosis Procedure (With LH Anti-Pinch Only).




Diagnosis Procedure (With LH and RH Anti-Pinch)
Regarding Wiring Diagram information, [1][2]Electrical Diagrams.
1.CHECK POWER WINDOW SWITCH OUTPUT SIGNAL





1. Read voltage signal between BCM connector and ground with oscilloscope when door lock and unlock switch (passenger side) is turned to "LOCK" or "UNLOCK".
2. Check that signals which are shown in the figure below can be detected during 10 second just after door lock and unlock switch (passenger side) is turned "LOCK" or "UNLOCK".

3. Check continuity between BCM connector M18 (A) terminal 40 and ground.





Is the inspection result normal?
YES - GO TO 4
NO - Repair or replace harness.
4.CHECK INTERMITTENT INCIDENT
Intermittent Incident.
YES - Inspection End.
