Park Lamps

WARNING: This page is about a different car, the 2006 Chrysler PT Cruiser. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: As part of the exterior lighting failsafe feature, upon ignition ON, all exterior park lamps and the headlamp low beams will illuminate regardless of the headlamp switch position if the instrument cluster cannot detect an input from the headlamp switch, or if there is a loss of data bus communication.

PARK LAMP DIAGNOSIS

CONDITION	POSSIBLE CAUSES	CORRECTION
PARK LAMP DOES NOT ILLUMINATE	1. Ineffective or missing bulb.	1. Test and replace park lamp bulb as required.
	2. Ineffective ground circuit.	2. Test and repair open park lamp ground circuit as required.
	3. Ineffective feed circuit.	3. Test and repair open park lamp feed circuit as required.
	4. Ineffective switch.	4. Test and replace left multi-function switch as required.
	5. Ineffective CCN inputs or outputs.	5. Use a diagnostic scan tool to test the CCN inputs and outputs as required. Refer to the appropriate diagnostic information.
	6. Ineffective TIPM inputs or outputs.	6. Use a diagnostic scan tool to test the TIPM inputs and outputs as required. Refer to the appropriate diagnostic information. Check for TIPM DTC's.
	7. Ineffective SCCM inputs or outputs.	7. Use diagnostic scan tool to diagnose LIN data bus. Refer to the appropriate diagnostic information. Check CCN for DTC's.
PARK LAMP DOES NOT EXTINGUISH	1. Ineffective switch.	1. Test and replace headlamp switch as required.
	2. Ineffective feed circuit.	2. Test and repair shorted park lamp feed circuit as required.
	3. Ineffective CCN inputs or outputs.	3. Use a diagnostic scan tool to test the CCN inputs and outputs as required. Refer to the appropriate diagnostic information.
	4. Ineffective TIPM inputs or outputs.	4. Use a diagnostic scan tool to test the TIPM inputs and outputs as required. Refer to the appropriate diagnostic information.
