Interior Lighting Ford Cutaway E350

Courtesy Lamps

The interior lamps are located on the roof trim panel. The interior lamps are energized anytime the lamp switches are activated or when the headlamp switch is turned counterclockwise to the stop position.

Illuminated Entry

On vehicles equipped with an optional remote keyless entry (RKE) system, the illuminated entry activates the interior lamps anytime an RKE transmitter unlock button is pressed. The length of time the illuminated entry system is energized is controlled by the RKE module. The illuminated entry feature will be canceled when any of the following conditions are met

1. 25 seconds have elapsed since the illuminated entry feature was activated and the interior lamp control is turned off.
2. The ignition is in the RUN or START position, and the interior lamp control is not activated.
3. The RKE transmitter lock button is pressed.

Refer to SYSTEM WIRING DIAGRAMS for schematic and connector information.

Inspection and Verification

1. Verify the customer concern.
2. Visually inspect for obvious signs of mechanical or electrical damage. VISUAL INSPECTION CHART Mechanical Electrical Interior lamp switch Door ajar switch(es) Central junction box (JB) fuse(s): 4 (15A) 22 (15A) Battery saver relay Interior lamp relay Bulbs Circuitry Connectors
3. If the cause is not visually evident, connect the diagnostic tool to the data link connector (DLC) and select the vehicle to be tested from the diagnostic tool menu. If the diagnostic tool does not communicate with the vehicle: check that the program card is correctly installed. check the connections to the vehicle. check the ignition switch position.
4. If the diagnostic tool still does not communicate with the vehicle, refer to the diagnostic tool operating manual.
5. Carry out the diagnostic tool data link test. If the diagnostic tool responds with: CAN, circuits fault; all electronic control units no response/not equipped, refer to «MODULE COMMUNICATIONS NETWORK»(/ford/cutaway-e350/2004-2007/remont/communication-devices/#module-communications-network) . System passed, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs and carry out the self-test diagnostics.
6. If the DTCs retrieved are related to the concern, go to the «INSTRUMENT CLUSTER DIAGNOSTIC TROUBLE CODE (DTC) INDEX»(/ford/cutaway-e350/2004-2007/remont/interiorillumination-lights/#interior-lighting) .
