id0903k7012400

Description

Possible cause

―  Front door latch and lock actuator terminal H (L.H.D.) / F (R.H.D.) and rear body control module (RBCM) terminal 3H

Diagnostic Procedure

Step	Inspection		Action
1	INSPECT DOOR LATCH SWITCH STUCK OFF OR OPEN CIRCUIT •  Open each door and verify that the door ajar warning light in the instrument cluster illuminates. •  Does the door ajar warning light illuminate?	Yes	Go to the next step.
		No	•  Inspect the door latch switch on the door in which the ajar warning light did not illuminate and for an open circuit in the wiring harness between the rear body control module (RBCM) and ground. (See FRONT DOOR LATCH SWITCH INSPECTION.) (See REAR DOOR LATCH SWITCH INSPECTION.) •  After inspection, go to Step 5.
2	DETERMINE IF MALFUNCTION CAUSE IS DOOR LOCK ACTUATOR •  Perform the lock/unlock operation using lock knob for each door. •  Is door locked/unlocked?	Yes	Go to the next step.
		No	•  Inspect the door lock actuator for the door which could not lock/unlock. (See FRONT DOOR LOCK ACTUATOR INSPECTION.) (See REAR DOOR LOCK ACTUATOR INSPECTION.) •  After inspection, go to Step 5.
3	DETERMINE IF MALFUNCTION CAUSE IS DOOR KEY CYLINDER •  Insert the auxiliary key into the door key cylinder and perform the lock/unlock operation using the auxiliary key. •  Does the lock knob switch between lock and unlock?	Yes	Go to the next step.
		No	•  Inspect the front door key cylinder switch. (See FRONT DOOR KEY CYLINDER SWITCH INSPECTION.) •  After inspection, go to Step 5.
4	INSPECT IF MALFUNCTION CAUSE IS OPEN CIRCUIT IN WIRING HARNESS BETWEEN FRONT DOOR KEY CYLINDER SWITCH AND REAR BODY CONTROL MODULE (RBCM) •  Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-D 2.2].) (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5].) (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5 (WITHOUT i-stop)].) •  Disconnect the front door latch and lock actuator connector. •  Disconnect the rear body control module (RBCM) connector. •  Inspect for continuity between the following terminals (vehicle wiring harness). ―  Front door latch and lock actuator terminal H (L.H.D.) / F (R.H.D.) and rear body control module (RBCM) terminal 3H •  Is there continuity?	Yes	Go to the next step.
		No	•  Repair or replace the wiring harness for an open circuit. •  After repair procedure, go to the next step.
5	VERIFY IF MALFUNCTION CAUSE WAS CORRECTED •  Has the malfunction symptom been eliminated?	Yes	Troubleshooting completed. (Explain the contents of the servicing to the customer.)
		No	Verify the malfunction symptom in the symptom troubleshooting chart and perform the applicable other malfunction diagnosis. (See SYMPTOM TROUBLESHOOTING ITEM TABLE [SECURITY AND LOCKS].)
