NG -- REPAIR OR REPLACE BACK DOOR POWER WINDOW REGULATOR MOTOR ASSEMBLY
OK -- Continue to next step.
2. INSPECT BACK DOOR POWER WINDOW REGULATOR SWITCH ASSEMBLY
(a) Using the Techstream, read the DTC when the back power window switch is operated.
(1) When DTC B1287 is output, proceed to A.
(2) When no DTC is output, proceed to B.
(3) When DTC B1241 is output, proceed to C.
C -- READ VALUE USING TECHSTREAM
B -- INSPECT BACK DOOR POWER WINDOW REGULATOR SWITCH ASSEMBLY
A -- INSPECT MULTIPLEX COMMUNICATION SYSTEM
3. READ VALUE USING TECHSTREAM
(a) Check the condition of the retract switch using the data list.
Standard:
Back Door
NG -- CHECK WIRE HARNESS (BACK DOOR ECU - POWER WINDOW MOTOR) (BACK DOOR ECU - GROUND)
OK -- Continue to next step.
4. WIRE HARNESS (BACK DOOR ECU - POWER WINDOW MOTOR) (BACK DOOR ECU - GROUND)
(a) Disconnect the B9 ECU connector.
(b) Disconnect the B11 motor connector.
(c) Check the continuity between the wire harness side connectors.

(d) Check the continuity between the B9 ECU connector and the body ground.
Standard:
NG -- REPAIR OR REPLACE HARNESS AND CONNECTOR
OK -- Continue to next step.
5. INSPECT BACK DOOR POWER WINDOW REGULATOR MOTOR ASSEMBLY
(a) Remove the motor.
(b) Apply battery voltage between the connector terminals and check that the motor gear rotates smoothly.
NOTE: Do not apply battery voltage to any terminals except terminals 4 and 5.
Standard:
NG -- REPLACE BACK DOOR POWER WINDOW REGULATOR MOTOR ASSEMBLY
OK -- CHECK AND REPLACE MULTIPLEX NETWORK DOOR ECU BACK
6. CHECK WIRE HARNESS (BACK DOOR ECU - POWER WINDOW MOTOR) (BACK DOOR ECU - GROUND)
