STEP 6. Check the wiring harness between C-219
ETACS-ECU connector terminal No.54 and E-13
rear power window sub switch (LH) connector
terminal No.6.

Prior to the wiring harness inspection, check interme-
diate connectors C-16 and D-14, and repair if neces-
sary.
• Check the communication line for open circuit.
Q: Is the check result normal?
YES :
Go to Step 7.
NO :
Repair the wiring harness.
STEP 7. Check whether the diagnosis code is
reset.
Check again if the diagnosis code is set to the
ETACS-ECU.
(1) Erase the diagnosis code.
(2) Turn the ignition switch from "LOCK" (OFF)
position to "ON" position.
(3) On completion, check that the diagnosis code is
reset.
Q: Is the diagnosis code set?
DIAGNOSIS CODE PROCEDURES

YES :
Replace the rear power window sub switch
(LH).
NO :
A poor connection, open circuit or other
intermittent malfunction is present in the LIN
bus lines between the rear power window
sub switch (LH) and the ETACS-ECU (Refer
to GROUP 00, How to Use Troubleshooting/
Inspection Service Points
− How to Cope
with Intermittent Malfunctions ).

TROUBLE JUDGEMENT
The ETACS-ECU receives signal from the rear
power window sub switch (RH). If signal cannot be
received at all, diagnosis code No.U1511 will be set.

COMMENT ON TROUBLE SYMPTOM
The M.U.T.-III shows a diagnosis code status as
active.
• Connector(s) or wiring harness in the LIN bus
lines between the rear power window sub switch
(RH) and the ETACS-ECU, the power supply sys-
tem of the rear power window sub switch (RH), or
the rear power window sub switch (RH) itself may
be defective.
The M.U.T.-III shows a diagnosis code status as
stored.
• If diagnosis code No.U1511 is stored as a past
trouble, carry out diagnosis with particular
emphasis on wiring and connector(s) in the LIN
bus line between the rear power window sub
switch (RH) and the ETACS-ECU, and the power
supply system of the rear power window sub
switch (RH). For diagnosis procedures, refer to
GROUP 00, How to Use Troubleshooting/Inspec-
tion Service Points
− How to Treat Past Trouble .
PROBABLE CAUSES
• Malfunction of the rear power window sub switch
(RH)
• Damaged harness wires and connectors
DIAGNOSIS PROCEDURE
STEP 1. Connector check: C-219 ETACS-ECU
connector, E-06 rear power window sub switch
(RH) connector

wiring harness side.
AC310506KQ
Connector E-06
(Harness side)
(2) Measure the resistance between the E-06 rear
power window sub switch (RH) connector
terminal No. 1 and the body earth.
OK: Continuity exists (2
Ω or less)
Q: Is the check result normal?
YES :
Go to Step 4.
NO :
Go to Step 3.
STEP 3. Check the wiring harness between E-06
rear power window sub switch (RH) connector
terminal No. 1 to body earth
AC502334AD
Harness side
Connector: E-06
Check the earth wires for open circuit.
NOTE:
AC901129
Connector: D-24
AH
Prior to the wiring harness inspection, check interme-
diate connector D-24, and repair if necessary.
Q: Is the check result normal?
YES :
The trouble can be an intermittent
malfunction (Refer to GROUP 00
− How to
use Troubleshooting/inspection Service
Points
− How to Cope with Intermittent
Malfunction ).
NO :
Repair the wiring harness.
STEP 4. Voltage measurement at the E-06 rear
power window sub switch (RH) connector.
AC502334AD
Harness side
Connector: E-06
(1) Disconnect the connector, and measure at the
wiring harness side.
(2) Ignition switch: ON position

(3) Measure the voltage between the E-06 rear
power window sub switch (RH) connector
terminal No. 4 and the body earth.
OK: System voltage
Q: Is the check result normal?
YES :
Go to Step 6.
NO :
Go to Step 5.
