INSPECTION AND VERIFICATION
1. Verify the customer concern.
2. Visually inspect the following for obvious signs of electrical damage:
VISUAL INSPECTION CHART
Electrical
-
Bulbs
-
Central junction box (CJB) fuse(s)
-
21 (15A)
-
24 (15A)
-
Circuitry
-
Vehicle security module (VSM) (if equipped with RKE)
-
Instrument cluster
-
Door ajar switches
3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
4. NOTE: Make sure to use the latest scan tool software release.
If the cause is not visually evident, connect the scan tool to the data link connector (DLC).
5. NOTE: The vehicle communication module (VCM) LED prove-out confirms power and ground from the DLC are provided to the VCM.
If the scan tool does not communicate with the VCM:
-
Check the VCM connection to the vehicle.
-
Check the scan tool connection to the VCM.
-
Refer to Information Bus (Module Communications Network), No Power To The Scan Tool, to diagnose no communication with the scan tool.
6. If the scan tool does not communicate with the vehicle:
-
Verify the ignition key is in the ON position.
-
Verify the scan tool operation with a known good vehicle.
-
Refer to Information Bus (Module Communications Network) to diagnose no response from the powertrain control module (PCM).
7. Carry out the network test.
-
If the scan tool responds with no communication for one or more modules, refer to Information Bus (Module Communications Network).
-
If the network test passes, retrieve and record the continuous memory DTCs.
8. Clear the continuous DTCs and carry out the self-test diagnostics for the instrument cluster and the VSM.
9. If the DTCs retrieved are related to the concern, go to the Instrument Cluster Diagnostic Trouble Code (DTC) Index and the Vehicle Security
Module (VSM) Diagnostic Trouble Code (DTC) Index. For all other DTCs, refer to Body Control Systems (Multifunction Electronic Control
Module). See: Diagnostic Trouble Code Tests and Associated Procedures/Instrument Cluster Diagnostic Trouble Code (DTC) Index See:
Diagnostic Trouble Code Tests and Associated Procedures/Vehicle Security Module (VSM) Diagnostic Trouble Code (DTC) Index
10. If no DTCs related to the concern are retrieved, GO to Symptom Chart. See: Symptom Related Diagnostic Procedures
Principles of Operation
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 (VSM) 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 VSM (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.
