Check Power Window Serial Link (Passenger Side)NIS001RO
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-37, "
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-64, "
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” 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”, “METER/M&A” and “I-KEY”. But, put a check mark
to “IPDM E/R” and “METER/M&A” because “UNKWN” is listed on the column of reception diagnosis of
the check sheet table.

For “ABS”, “UNKWN” is displayed on “ECM”, “TCM”, “METER/M&A”, “STRG” and “ICC”. But, put a
check mark to “ECM”, “TCM” and “STRG” because “UNKWN” is listed on the column of reception diag-
nosis of the check sheet table.

–: There is no received unit or the unit is not in the condition that reception diagnosis is performed.
Display Results (Past)

OK: Normal

0: There is malfunction now.

1 – 39: Displays when it is normal at present and finds malfunction in the past. It increases like 0 →1→ 2...38 →39 after returning to the
normal condition whenever IGN OFF →ON. If it is over 39, it is fixed to 39 until the self-diagnostic results are erased. It returns to 0
when malfunction is detected again in the process.

CAN COMMUNICATIONPFP:23710
System DescriptionNKS0034C
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN-H line, CAN-L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
