Result:





B -- GO TO LIN COMMUNICATION SYSTEM
A -- Continue to next step.
2. CHECK FOR DTC (B2312)
(a) Check if DTC B2312 is output.

Result:





B -- GO TO DTC B2312
A -- Continue to next step.
3. READ VALUE USING INTELLIGENT TESTER OR TECHSTREAM (REAR MOTOR LH)
(a) Use the Data List to check if the power window regulator motor is functioning properly.
(1) Intelligent tester

RL DOOR MOTOR:





(2) Techstream

RL-Door Motor:





OK:
Tester display changes normally when rear power window switch LH is operated.
NG -- CHECK HARNESS AND CONNECTOR (REAR DOOR ECU LH - REAR SWITCH LH)
OK -- REPLACE REAR POWER WINDOW REGULATOR MOTOR ASSEMBLY LH
4. CHECK HARNESS AND CONNECTOR (REAR DOOR ECU LH - REAR SWITCH LH)
