1. CHECK POWER WINDOW SWITCH OUTPUT SIGNAL
With CONSULT-II
Check (“CDL LOCK SW ”, “CDL UNLOCK SW”) in DATA MONITOR mode for “POWER DOOR LOCK SYS-
TEM” with CONSULT-II. Refer to GW-30, "
DATE 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 >> Power window serial link is OK.
NG >> GO TO 2.

d. Reception item of “BCM”: On “TCM”, “UNKWN” is indicated. This means BCM cannot receive the signal
from TCM. Draw a line to indicate an error between BCM and TCM (line 2-d in the figure).
e. Reception item of “EPS” and “INTELLIGENT KEY”: “UNKWN” is not indicated. This indicates normal com-
munication between EPS and I-KEY and their receiving units. Do not draw any line.
NOTE:
On CAN DIAG SUPPORT MNTR (without PAST), “UNKWN” is indicated even though the item is not used
in the trouble diagnosis. For the details of each item on CAN diagnostic support monitor, refer to LAN-44,
"CAN Diagnostic Support Monitor" .
