Check front door lock assembly LH (key cylinder switch) (“KEY
CYL UN-SW”) in “DATA MONITOR” mode for “POWER DOOR
LOCK SYSTEM” with CONSULT-II. Refer to GW-34, "
DATA
MONITOR" .
Without CONSULT-II
Check voltage between main power window and door lock/unlock switch connector and ground.
OK or NG
OK >> Front door lock assembly LH (key cylinder switch) is OK.
NG >> GO TO 2.
2. CHECK FRONT DOOR LOCK ASSEMBLY LH (KEY CYLINDER SWITCH) CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect main power window and door lock/unlock switch and front door lock assembly (key cylinder
switch).
3. Check continuity between main power window and door lock/
unlock switch connector D7 terminals 4, 6 and front door lock
assembly LH (key cylinder switch) connector D14 terminals 1, 6.
OK or NG
OK >> GO TO 3.

Power Window Serial Link Check Front LH and RHEIS002V8
1. CHECK SERIAL LINK OUTPUT SIGNAL
With CONSULT-II
Check door lock and unlock switch (“LOCK SW DR/AS”, “UNLK SW DR/AS”) in DATA MONITOR mode for
“MULTI REMOTE ENT” with CONSULT-II. Refer to GW-34, "
DATA MONITOR" .

When door lock and unlock switch is turned to LOCK

When door lock and unlock switch is turned to UNLOCK
Without CONSULT-II
1. Remove key from ignition switch, and the door of driver side and passenger side is closed.
2. Check the signal between BCM connector and ground with oscilloscope when door lock and unlock
switch (front LH and front RH) 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
(front LH and front RH) is turned “LOCK” or “UNLOCK”.
OK or NG
OK >> GO TO 2.
NG >> GO TO 3.
2. CHECK BCM OUTPUT SIGNAL
Check power window serial link (“POWER WINDOW DOWN”) in “ACTIVE TEST” mode with CONSULT-II.
Refer to GW-34, "
ACTIVE TEST" .
When “ACTIVE TEST” is executed, is the window of driver side and
passenger side lowered?
YES or NO
YES >> Further inspection is necessary. Refer to GW-36, "Tro u-
ble Diagnoses Symptom Chart" .
NO >> Replace BCM.LOCK SW DR/AS : ON
