All interior light's not working ? Instrument cluster , dome light's , switch light , instrument panel , map ,reading lamps etc...... Probably not a fuse problem , more then likely the LCM - lighting control module . Do you know anything about automotive electronics ? Control modules ? DTC'S - diagnostic trouble code's ?
Illuminated Entry
The illuminated entry system:
- is controlled by the lighting control module.
- provides courtesy lighting upon entry to and exit from the vehicle.
The keyless entry keypad illuminates when any keyless entry keypad button is pressed, regardless of the ignition switch position. The keyless entry keypad remains illuminated for five seconds after a handle is raised or for five seconds following the last keypad button pressed.
Courtesy lamps will be illuminated for 25 (±1) seconds which includes a theater lighting ramp-up time (two seconds). This time interval does not include the theater lighting ramp-down time. Courtesy lamps will be turned off before the 25 (±1)-second timeout if the ignition switch is turned to the RUN or ACC position.
NOTE: When the illuminated entry feature is activated by using the keyless entry remote transmitter, the keyless entry keypad does NOT illuminate.
The illuminated entry system has the following additions to accommodate the keyless entry system:
- Pressing any button on the keyless entry keypad or pressing the UNLOCK button on the keyless entry remote transmitter will activate the illuminated entry system (with theater ramp-up). When the driver door module detects a button press, it sends a signal on the J1850 communication network activating the courtesy lamps. The keypad will remain illuminated for five seconds following the illuminated entry ON signal transition or for five seconds following the last keypad button press.
- If the keyless entry keypad 7/8 and 9/0 buttons are pressed concurrently (to lock the doors) or the LOCK button on the keyless entry remote transmitter is pressed:
- the lighting control module will turn off the lamps by sensing the all doors lock signal.
- the driver door module will also turn OFF the keyless entry keypad illumination when the last two keyless entry keypad buttons are pressed concurrently.
-
Lamps, Courtesy
Courtesy lamps can be turned on by using the panel dim switch located on the headlamp switch assembly or by opening any door. A theater lighting feature gradually increases or decreases the light intensity when switched by opening or closing a door.
Courtesy lamps (controlled by the lighting control module) are activated by using the dome lamp switch (instant ON/OFF response) or when a door is ajar. The following lamps illuminate for courtesy lighting:
- instrument panel courtesy lamps
- front map lamps
- rear reading lamps
-
Inspection and Verification
-
Verify the customer's concern by operating the courtesy and demand lamps to duplicate the condition.
-
Inspect to determine if one of the following electrical concerns apply:
VISUAL INSPECTION CHART
Electrical
- Damaged lamps
- Damaged switches
- Stuck switches
- Open fuse junction panel Fuses:
- 1 (10A)
- 4 (10 A)
- 5 (10 A)
- 7 (15A)
- 13 (15A)
- 19 (10A)
- 25 (10A)
- 31 (15A)
- 39 (10A)
- Open power distribution box Fuse 9 (40A)
- Open bulbs
- Loose connectors
- Corroded connectors
-
If inspection reveals an obvious concern that is readily serviced, correct the concern before continuing with Inspection and Verification.
-
If the concern remains after the inspection, connect the Rotunda New Generation Star (NGS) Tester 007-00500 or equivalent to the data link connector (DLC) located beneath the instrument panel to perform Data Link Diagnostics Test. If the NGS responds with NO RESPONSE/NOT EQUIPPED for the lighting control module, go to Pinpoint Test AA . If the NGS responds with NO RESPONSE/NOT EQUIPPED for the driver door module, go to Pinpoint Test AB . If the Data Link Diagnostic test is passed for the lighting control module and driver door module, retrieve continuous DTCs and execute self test diagnostics for the suspect module(s).
-
If self test is passed and no DTCs are retrieved, GO to the Symptom Chart to continue diagnostics.
-
If DTCs are retrieved for the lighting control module, go to the Lighting Control Module (LCM) Diagnostic Trouble Code (DTC) Index to continue diagnosis. If DTCs are retrieved for the driver door module, go to the Driver Door Module (DDM) Diagnostic Trouble Code (DTC) Index to continue diagnostics.
-
If the lighting control module cannot be accessed by the NGS tester, go to Pinpoint Test AA . If the driver door module cannot be accessed by the NGS tester, go to Pinpoint Test AB .
Rotunda Service Bay Diagnostic System (SBDS®) 001-00001 may also be used to diagnose this system.
