Description

Possible cause

―  Rear body control module (RBCM) terminal 4M and liftgate/trunk lid opener switch terminal C

―  LF control unit terminal G and request switch (LF) terminal D

―  LF control unit terminal E and request switch (RF) terminal D

―  Start stop unit terminal 1P and door lock link switch (driver's side) terminal D

―  Start stop unit terminal 1AF and ground

―  Start stop unit terminal 2B and ground

―  power window main switch terminal 1E and rear body control module (RBCM) terminal 3D

―  power window main switch terminal 1E and rear body control module (RBCM) terminal 3D

Diagnostic Procedure

Step	Inspection		Action
1	DETERMINE IF MALFUNCTION CAUSE IS DOOR LOCK •  Inspect the door lock/unlock operation using the request switch. •  Does it operate normally?	Yes	Go to the next step.
		No	Refer to "Advanced keyless entry system does not operate" malfunction diagnosis and perform the inspection. (See ADVANCED KEYLESS ENTRY SYSTEM DOES NOT OPERATE [SECURITY AND LOCKS].)
2	INSPECT IF MALFUNCTION CAUSE IS SHORT TO GROUND IN WIRING HARNESS BETWEEN POWER WINDOW MAIN SWITCH AND REAR BODY CONTROL MODULE (RBCM) •  Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5].) •  Disconnect the rear body control module (RBCM) •   Inspect for continuity between the following wiring harness terminals (vehicle wiring harness side) and body ground. ―  Rear body control module (RBCM) terminal 3D •  Is there continuity?	Yes	•  Repair or replace the wiring harness which is shorted to ground. •  After repair procedure, go to Step 5.
		No	Go to the next step.
3	INSPECT IF MALFUNCTION CAUSE IS SHORT TO POWER SUPPLY IN WIRING HARNESS BETWEEN POWER WINDOW MAIN SWITCH AND REAR BODY CONTROL MODULE (RBCM) •  Verify that the rear body control module (RBCM) •  Connect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5].) •  Measure the voltage at the following terminals (vehicle wiring harness). ―  Rear body control module (RBCM) terminal 3D •  Is there continuity?	Yes	•  Repair or replace the wiring harness which is shorted to power supply. •  After repair procedure, go to Step 5.
		No	Go to the next step.
4	INSPECT IF MALFUNCTION CAUSE IS OPEN CIRCUIT IN WIRING HARNESS BETWEEN POWER WINDOW MAIN SWITCH AND REAR BODY CONTROL MODULE (RBCM) •  Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5].) •  Disconnect the power window main switch •  Inspect for continuity between the following terminals (vehicle wiring harness). ―  Power window main switch terminal 1E and rear body control module (RBCM) terminal 3D •  Is there continuity?	Yes	•  Replace the power window main switch (See POWER WINDOW MAIN SWITCH REMOVAL/INSTALLATION.) •  After repair, go to the next step.
		No	•  Repair or replace the wiring harness for an open circuit. •  After repair, go to the next step.
5	VERIFY IF MALFUNCTION CAUSE WAS CORRECTED •  Does the exterior open/close function operate using the request switch?	Yes	Troubleshooting completed. (Explain the contents of the servicing to the customer.)
		No	If the malfunction has not been resolved, repeat the inspection from Step 1.
