Dash back cluster lights out only the cluster back lights all else works. on a 2006 chevy impala ss could it be in the body control module if so could it be reprogramed


Could be the instrument cluster .GM had instrument cluster problems for 2003 to 2006 . Wouldn't think BCM reprogramming to be an issue . Having a qualified repair shop or dealer check for DTC'S - diagnostic trouble codes an view data parmeters would be the first place to start .
When the ignition switch is turned to the RUN position, the instrument panel cluster (IPC), radio VF display, and the HVAC control assembly turns ON at maximum brightness. When the headlamp switch is in the PARK or HEADLAMP ON position, all incandescent and LED back lighting turn ON at the dimming level indicated by the instrument panel (I/P) dimmer switch. The dimmer switch is used to increase and decrease the brightness of the interior backlighting components. The BCM supplies a voltage reference through the I/P dimming voltage reference circuit to the interior lamp dimmer switch, which is part of the headlamp switch. When the dimmer switch is placed in a desired brightness position, reference voltage is applied through the dimmer switch rheostat and the I/P lamps dimmer switch signal circuit to the BCM. The BCM interprets this voltage signal, then applies a pulse width modulated (PWM) voltage through the I/P lamps supply voltage circuits and the LED dimming supply circuit to all related interior lamps, illuminating them to the desired level of brightness.

DTC B2652
Circuit/System Description
The BCM supplies a voltage reference through the instrument panel (I/P) dimming voltage reference circuit to the interior lamp dimmer switch, which is part of the headlamp switch. When the dimmer switch is placed in a desired position, reference voltage is applied through the dimmer switch rheostat and the I/P lamps dimmer switch signal circuit to the BCM. The BCM interprets this voltage signal, then applies a pulse width modulated (PWM) voltage through the instrument panel lamp supply voltage circuit illuminating the components listed below:
• Headlamp switch
• Instrument panel cluster (IPC)
• Driver and passenger window switches
• Driver and passenger door lock switches
• Outside rearview mirror switch

Circuit/System Testing
Ignition OFF, disconnect the (C2) harness connector at the BCM.
Verify that a test lamp illuminates between the B+ circuit terminal 2 and ground.
? If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance. If the circuit tests normal and the B+ circuit fuse is open, test the supply voltage circuits listed below for a short to ground.
• Instrument panel lamp supply voltage circuit terminal 3 C2
• Instrument panel lamp supply voltage circuit terminal 3 C6
Ignition OFF, disconnect all of the instrument panel lamp components fed by the BCM supply voltage circuits listed below.
• Instrument panel supply voltage circuit -terminal 3 C2
• Instrument panel supply voltage circuit -terminal 3 C6
Ignition ON, with a scan tool clear the DTC.
Operate the vehicle within the conditions for running the DTC and verify the DTC does not reset.
? If the DTC resets, test the instrument panel lamp supply voltage circuit for a short to ground. If the circuit test normal, replace the BCM.
Reconnect each component one at a time and verify that the DTC does not reset as current.
? If the DTC resets as current, test or replace the component responsible for setting the DTC.

Fuse location for interior lighting 2007 f150 fxt4x4 also is there 2 dash lights it doesn't seem to be as bright as it used to


dash lights it doesn't seem to be as bright as it used to ???? Dimmer switch on full bright ? Visual Inspection Chart Electrical
  • Bulbs
  • Central junction box (CJB) fuse 24 (15A)
  • Circuitry
  • Vehicle security module (if equipped with RKE)
  • Instrument cluster
  • Door ajar switches

Interior Lighting The interior lamp system is separated into 2 subsystems: the interior lamp subsystem and the on-demand lamp subsystem. The dome light and front map light on-demand lamps are also part of the interior lamp subsystem.
An on-demand interior lamp will only illuminate when its specific switch is activated. On-demand lamps consist of the front map light and the dome light.
The instrument cluster illuminates the interior lamps when any door is ajar, when an unlock signal is received by the vehicle security module (if equipped with remote keyless entry (RKE) or the dimmer switch is rotated to the ON position. The instrument cluster will turn off the interior lamps when all doors are closed, the vehicle security module (if equipped with RKE) receives a lock signal, 25 seconds have elapsed since the illuminated entry feature was activated, or the dimmer switch is rotated to the OFF position.
The vehicle is also equipped with a battery saver feature. The battery saver feature provides automatic shutoff of the demand lamps, courtesy lamps, and the warning chimes after a specific period of time has elapsed in order to save battery power.

  1. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
  1. 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.
  1. If the diagnostic tool still does not communicate with the vehicle, refer to the diagnostic tool operating manual.
  1. 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.
  1. 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.
  1. If no DTCs related to the concern are retrieved, GO to Symptom Chart .
  2. Symptom Chart Condition Possible Sources Action
    • The interior lamps are inoperative
    • Fuse
    • Circuitry
    • Instrument cluster
    • Dimmer control switch
    • Go To Pinpoint Test A .
    Pinpoint Test A: The Interior Lamps Are Inoperative
    Normal Operation On vehicles equipped with remote keyless entry (RKE), the door ajar switches are hardwired to the vehicle security module. The vehicle security module monitors the status of all door ajar switches, and when a door is opened, transmits a dome lamp ON signal to the instrument cluster through UART based protocol (UBP) circuit 1906 (PK), indicating a door has been opened. When the instrument cluster receives the dome lamp ON signal from the vehicle security module, the instrument cluster energizes the interior lamp circuits, which illuminates the interior lamps and, if equipped, the puddle lamps in the exterior mirrors.
    On vehicles without RKE, the door ajar switches are hardwired to the instrument cluster. When the driver or passenger door is opened, the instrument cluster receives a ground signal from the driver door ajar switch through circuit 344 (BK/YE), or from the passenger door ajar switch through circuit 345 (BK/PK), and the instrument cluster energizes the interior lamp circuits, causing the interior lamps to illuminate.
    The dimmer control switch can be used to turn the interior lamps ON or OFF when the doors are closed. The interior lamp defeat switch can be used to turn the interior lamps OFF when the doors are open.
      Possible Causes
    • Fuse
    • Circuit 53 (BK/LB) open or short to ground
    • Circuit 57 (BK) open
