Front Door Key Cylinder Switch Check AIS004QU
1. CHECK DOOR KEY CYLINDER SWITCH INPUT SIGNAL
With CONSULT-II
Check (“KEY CYL LK-SW”, “KEY CYL UN-SW”) in “DATA MONITOR” mode for “POWER DOOR ROCK SYS-
TEM” with CONSULT-II. Refer to BL-38, "
Data Monitor"
Without CONSULT-II
1. Turn ignition switch OFF.
2. Check voltage between power window main switch connector and ground.
OK or NG
OK >> Further inspection is necessary. Refer to symptom chart.
NG >> GO TO 2.
2. CHECK HARNESS CONTINUITY
1. Disconnect power window main switch and front door key lock assembly (driver side) connector.
2. Check continuity between power window main switch connector D6 terminals 4, 6 and front door lock assembly (driver side) con-
nector D10 terminals 1, 6.
OK or NG
OK >> GO TO 3.
NG >> Repair or replace harness.

Power Window Serial Link Check (Passenger Side)AIS004QV
1. CHECK POWER WINDOW SWITCH OUTPUT SIGNAL
With CONSULT-II
Check (“CDL LOCK SW ”, “CDL UNLOCK SW”) in DATA MONITOR mode for “REMOTE KEYLESS ENTRY
SYSTEM” with CONSULT-II. Refer to BL-38, "
Data Monitor" .
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 >> GO TO 2.
NG >> GO TO 3.
2. CHECK BCM OUTPUT SIGNAL
Check (“POWER WINDOW DOWN”) in “ACTIVE TEST” mode for “REMOTE KEYLESS ENTRY SYSTEM”
with CONSULT-II. Refer to BL-67, "
Active Test"
OK or NG
OK >> Further inspection is necessary. Refer to symptom
chart.
NG >> Replace BCM.

5. Confirm the unit name that “UNKWN” is displayed on the copy of “CAN DIAG SUPPORT MNTR” screen
of “BCM”, “METER A/C AMP” and “ABS” as well as “ENGINE”. And then, put a check mark to the check
sheet table.
NOTE:
For “BCM”, “UNKWN” is displayed on “IPDM E/R” and “I-KEY”. But put a check mark to “IPDM E/R”
because “UNKWN” is listed on the column of reception diagnosis on the check sheet table.
For “METER A/C AMP”, “UNKWN” is not displayed. Do not put a check to it.
For “ABS”, “UNKWN” is displayed on “METER/M&A” and “ICC”. But, do not put a check mark to their
columns of reception diagnosis of the check sheet table because “UNKWN” is not listed.
