Diagnostic Procedure

Step	Inspection		Action
1	VERIFY FRONT BODY CONTROL MODULE (FBCM) DTCs AGAIN • Clear the DTC for the front body control module (FBCM) using the M-MDS. (See CLEARING DTC [FRONT BODY CONTROL MODULE (FBCM)].) • Retrieve the front body control module (FBCM) DTCs using the M-MDS. (See DTC INSPECTION [FRONT BODY CONTROL MODULE (FBCM)].) • Is the same DTC displayed?	Yes	Go to the next step.
1		No	Go to Step 12.
2	LIMITS TO MALFUNCTIONING LIGHT • Operate the light switch in TNS position. • Are there any lights among the following which are not illuminated? ― Parking light (LH) ― Parking light (RH)	Yes	All lights are not illuminated: • Go to the next step. Parking light (LH) is not illuminated: • Parking light (bulb type): ― Go to Step 5. • Parking light (LED type): ― Go to Step 6. Parking light (RH) is not illuminated: • Parking light (bulb type): ― Go to Step 8. • Parking light (LED type): ― Go to Step 9.
2		No	Go to Step 11.
3	INSPECT FRONT BODY CONTROL MODULE (FBCM) CONNECTOR • Switch the ignition to off. • Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5 (WITHOUT i-stop)].) (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5].) (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-D 2.2].) • Disconnect the front body control module (FBCM) connector. • Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection. • Is the connector normal?	Yes	Go to the next step.
3		No	Repair or replace the connector, then go to Step 11.
4	INSPECT FOR SHORT TO GROUND IN PARKING LIGHT CONTROL CIRCUIT • Verify that the front body control module (FBCM) connector is disconnected. • Inspect for continuity between front body control module (FBCM) terminal 1J (wiring harness-side) and body ground. • Is there continuity?	Yes	Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals: • Front combination light (LH) terminal D—Front body control module (FBCM) terminal 1J • Front combination light (RH) terminal D—Front body control module (FBCM) terminal 1J If there is a common connector: • Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to ground. • Repair or replace the malfunctioning part. If there is no common connector: • Repair or replace the wiring harness which has a short to ground. Go to Step 11.
4		No	Go to Step 11.
5	INSPECT PARKING LIGHT BULB (LH) • Inspect the parking light bulb (LH). • Is the parking light bulb (LH) normal?	Yes	Go to the next step.
5		No	Replace the parking light bulb (LH), then go to Step 11. (See PARKING LIGHT BULB REMOVAL/INSTALLATION.)
6	INSPECT FRONT COMBINATION LIGHT (LH) CONNECTOR • Switch the ignition to off. • Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5 (WITHOUT i-stop)].) (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5].) (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-D 2.2].) • Disconnect the front combination light (LH) connector. • Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection. • Is the connector normal?	Yes	Parking light (bulb type): • Go to Step 11. Parking light (LED type): • Go to the next step.
6		No	Repair or replace the connector, then go to Step 11.
