Check Door Lock and Unlock Switch NIS001X0
1. CHECK POWER WINDOW SWITCH OUTPUT SIGNAL
With CONSULT-II
Check (“CDL LOCK SW ”, “CDL UNLOCK SW”) in DATA MONITOR mode with CONSULT-II.
Without CONSULT-II
1. Remove key from ignition switch, and the door of driver side and passenger side is closed.
2. Check signal between BCM connector and ground with oscilloscope when door lock and unlock switch
(driver side and passenger side) is turned “LOCK” or “UNLOCK”.
3. Make sure signals which are shown in the figure below can be detected during 10 second just after door
lock and unlock switch (driver side and passenger side) is turned “LOCK” or “UNLOCK”.
OK or NG
OK >> Door lock and unlock switch is OK.
NG >> GO TO 2.
