Enter vehicle info. year , make , model an engine . Under system click on lighting , then under subsystem click on interior lighting . Click the sear search button then the blue link. I see one fuse in the CJB F24 - 15 amp . Also i see battery saver relay . The instrument cluster energizes the battery saver relay .
Principles of Operation
Vehicles equipped with remote keyless entry (RKE) have an illuminated entry feature, which enables the instrument cluster to illuminate the interior lamps (and if equipped, the puddle lamps in the exterior mirrors) when an unlock signal is received from the vehicle security module through the UBP network, or when any of the doors are opened. The instrument cluster controls the interior lamps illuminated entry feature by activating the battery saver relay. When active, the illuminated entry feature will be canceled when any of the following conditions are met:
- 25 seconds have elapsed since the illuminated entry feature was activated and the interior lamp control is not activated (door ajar or dimmer control switch ON).
- On vehicles equipped with RKE, the instrument cluster received a request from the vehicle security module (remote transmitter lock button pressed) and the interior lamp control is not activated.
- The ignition is in the RUN or START position and the interior lamp control is not activated.
For vehicles equipped with RKE, the instrument cluster illuminates the interior lamps when any door is open. The interior lamps shut off when the doors are closed and the illuminated entry feature is not active or when the vehicle speed is greater than 15 km/h (6 mph). The interior lamps are not reactivated until the vehicle speed is less than 15 km/h (6 mph) and a new door open signal is received.
For vehicles without RKE, the instrument cluster illuminates the interior lamps and puddle lamps (if equipped) when any door is open. The instrument cluster will turn the interior lamps and puddle lamps (if equipped) OFF when the doors are closed.
Power to the on-demand lamps, illuminated vanity mirrors and map lamps are controlled by the battery saver relay.
Inspection and Verification
- Verify the customer concern.
- Visually inspect the following for obvious signs of electrical damage:
Visual Inspection Chart
- Central junction box (CJB) fuse 24 (15A)
- Vehicle security module (if equipped with RKE)
- Instrument cluster
- Door ajar switches
- If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
- 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.
- If the diagnostic tool still does not communicate with the vehicle, refer to the diagnostic tool operating manual.
- Carry out the diagnostic tool data link test. If the diagnostic tool responds with:
- CAN, ISO or UBP circuits fault; all electronic control units no response/not equipped, refer to Section 418-00 .
- No response/not equipped for instrument cluster, refer to Section 413-01 .
- No response/not equipped for vehicle security module, refer to Section 419-10 .
- System passed, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs, and carry out the self-test diagnostics for the instrument cluster.
- System passed, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs, and carry out the self-test diagnostics for the vehicle security module.
- If the DTCs retrieved are related to the concern, go to the Instrument Cluster Diagnostic Trouble Code (DTC) Index or the Vehicle Security Module Diagnostic Trouble Code (DTC) Index.
- If no DTCs related to the concern are retrieved, GO to Symptom Chart .
