All Illumination Does Not Dim Or Increase Brightness

  1. A1 CHECK FOR RECORDED DIAGNOSTIC TROUBLE CODES (DTCS) FROM THE BCM (BODY CONTROL MODULE) SELF-TEST 
    • Ignition ON.
    • Using a diagnostic scan tool, perform the BCM  self-test.

    Is DTC B1436:01 present? 

    1. Yes  : GO to A2 
    2. No  : GO to  A4
  2. A2 REPEAT THE BCM (BODY CONTROL MODULE) SELF-TEST WITH THE HEADLAMP SWITCH DISCONNECTED 
    • Ignition OFF.
    • Disconnect Headlamp Switch.
    • Ignition ON.
    • Using a diagnostic scan tool, clear the BCM  Diagnostic Trouble Codes (DTCs).
    • Perform the BCM  self-test.

    Is DTC B1436:01 still present? 

    1. Yes  : GO to A3 
    2. No  : INSTALL a new headlamp switch.

      REFER to: HEADLAMP SWITCH .

  3. A3 CHECK THE DIM UP AND DIM DOWN CIRCUITS FOR A SHORT TO GROUND 
    • Ignition OFF.
    • Disconnect BCM C2280G  .
    • Measure:
      Positive Lead Measurement/Action Negative Lead
      C205-3  OHM Ground
      C205-6  OHM Ground

    Are the resistances greater than 10, 000 ohms? 

    1. Yes  : GO to  A9
    2. No  : REPAIR the affected circuit.
  4. A4 CHECK THE INSTRUMENT PANEL DIMMER SWITCH 

    Does the instrument panel dimmer switch pass the component test? 

    1. Yes  : GO to A5 
    2. No  : INSTALL a new headlamp switch.

      REFER to: HEADLAMP SWITCH .

  5. A5 CHECK THE DIM UP AND DIM DOWN CIRCUITS FOR AN OPEN 
    • Disconnect BCM  C2280G.
    • Measure:
      Positive Lead Measurement/Action Negative Lead
      C205-3  OHM C2280G-3 
      C205-6  OHM C2280G-7 

    Are the resistances less than 3 ohms? 

    1. Yes  : GO to A6 
    2. No  : REPAIR the affected circuit.
  6. A6 CHECK THE DIM UP AND DIM DOWN CIRCUITS FOR A SHORT TOGETHER 
    • Measure:
      Positive Lead Measurement/Action Negative Lead
      C205-3  OHM C205-6 

    Is the resistance greater than 10, 000 ohms? 

    1. Yes  : GO to A7 
    2. No  : REPAIR the circuits.
  7. A7 CHECK FOR GROUND TO THE HEADLAMP SWITCH 
    • Measure:
      Positive Lead Measurement/Action Negative Lead
      C205-4  OHM Ground

    Is the resistance less than 3 ohms? 

    1. Yes  : GO to A8 
    2. No  : REPAIR the circuit.
  8. A8 CHECK THE DIM UP AND DIM DOWN CIRCUITS FOR A SHORT TO VOLTAGE 
    • Ignition ON.
    • Measure:
      Positive Lead Measurement/Action Negative Lead
      C205-3  VOLTAGE Ground
      C205-6  VOLTAGE Ground

    Is any voltage present? 

    1. Yes  : REPAIR the affected circuit.
    2. No  : GO to A9 
  9. A9 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION 
    • Disconnect and inspect all BCM  connectors.
    • Repair:
      • corrosion (install new connector or terminals - clean module pins)
      • damaged or bent pins - install new terminals/pins
      • pushed-out pins - install new pins as necessary
    • Reconnect the BCM  connectors and all previously disconnected illumination system connectors. Make sure all connectors seat and latch correctly.
    • Operate the system to determine if the concern is still present.

    Is the concern still present? 

    1. Yes  : CHECK OASIS  for any applicable Technical Service Bulletins (TSBs). If a TSB  exists for this concern, DISCONTINUE this test and FOLLOW the TSB  instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new BCM.

      REFER to: BODY CONTROL MODULE (BCM) .

    2. No  : The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
