1.CHECK POWER WINDOW SWITCH OUTPUT SIGNAL
With CONSULT-III
Check (“CDL LOCK SW ”, “CDL UNLOCK SW”) in DATA MONITOR mode for “REMOTE KEYLESS ENTRY
SYSTEM” with CONSULT-III. Refer to BL-36, "
CONSULT-III Function (BCM)".
Without CONSULT-III
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 wit h 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 T EST” mode for “REMOTE KEYLESS ENTRY SYSTEM”
with CONSULT-III. Refer to BL-60, "

Power is at all times supplied
 through 20A fuse [No. 75, located in the IPDM E/R]
 to rear window defogger relay terminals 3,
 through 20A fuse [No. 80, located in the IPDM E/R]
 to rear window defogger relay terminals 6,
 through 15A fuse [No. 32, located in the fuse block (J/B)]
 to A/C and AV switch terminal 1,
 through 50A fusible link (letter M, located in the fuse and fusible link box)
 to BCM terminal 55,
 through 15A fuse [No. 22, located in the fuse block (J/B)]
 to BCM terminal 42.
With the ignition switch turned to ON or START position,
Power is supplied
 through 15A fuse [No. 1, located in the fuse block (J/B)]
 to BCM terminal 38.
 through 10A fuse [No. 12, located in the fuse block]
 to rear window defogger relay terminal 1,
