Lighting and Horns: Description and Operation
LAMP SYSTEMSThe Plymouth Prowler utilizes lighting on the interior and exterior of the vehicle for illuminating and indicating purposes. Lighting circuits are protected by fuses. Lighting circuits require an overload protected power source, ON/OFF device, lamps and body ground to operate properly. Plastic lamps require a wire in the harness to supply body ground to the lamp socket. Replace sockets and bulbs that are corroded.
Some of the interior and exterior lighting functions are governed by the body controller. The headlamp and the door ajar switches provide signals to the body controller. The body controller in turn activates relay(s) in order to provide either a ground or feed line to the appropriate lamp(s).
Wire connectors can make intermittent contact or become corroded. Before coupling wire connectors, inspect the terminals inside the connector. Male terminals should not be bent or disengaged from the insulator. Female terminals should not be sprung open or disengaged from the insulator. Bent and sprung terminals can be repaired using needle nose pliers and pick tool. Corroded terminals appear chalky or green. Corroded terminals should be replaced to avoid recurrence of the problem symptoms.
Begin electrical system failure diagnosis by testing related fuses in the fuse block and power distribution center. Verify that bulbs are in good condition and test continuity of the circuit ground. Refer to Wiring Diagrams, for component location and circuit information.
DAYTIME RUNNING LAMP (CANADA)
The Prowler vehicles built for use in Canada are equipped with a Daytime Running Lamp (DRL) system. The DRL system is controlled by the Daytime Running Lamp Module located on the outboard side of the left hand support bracket. Refer to Wiring Diagrams, for component locations and circuit information.
The DRL system operates the Park & Turn signal lamps with the headlamp switch OFF, park brake released and the ignition ON. The Park & Turn signal lamps operate normally when the headlamps are turned ON.
HEADLAMP TIME DELAY SYSTEM
The optional Headlamp Time Delay system is controlled by the Body Control Module (BCM) and a relay located in the junction block. Refer to the Owner's Manual for more information.
The headlamp time delay system can be activated by turning ON the headlamps when the engine is running, turn OFF the ignition switch, then turn OFF the headlamp switch. The BCM will allow the headlamps to remain ON for 90 seconds before they automatically turn off.
ILLUMINATED ENTRY
The Illuminated Entry System is available on vehicles equipped with the Remote Keyless Entry system. The Illuminated Entry System turns ON the courtesy lamps when the remote keyless entry system is activated. The Remote Keyless Entry Module and the Body Controller are used to control the system.
The Illuminated Entry System also turns ON the courtesy lamps (and ignition switch lamp) when door is opened. The courtesy lamps will remain ON while the door is open, then fade to OFF 30 seconds (±1 second) after the last door is closed.
The courtesy and ignition switch lamps will fade to OFF immediately when the ignition is switched to ON.
The Illuminated Entry System cannot be activated during the 30 second (±1 1 second) period after the ignition switch is turned OFF. After a door is opened and closed during this 30 second period, the system will function as previously described.
When the battery voltage has been interrupted to the Illuminated Entry System, the system will not function until the remote keyless entry UNLOCK is actuated.
Courtesy lamps will turn on for 30 seconds (±1 1 second) and fade to OFF over a 5 second period.
