    • Press the dimmer switch up until the illumination reaches full brightness.
    • Measure:
      Positive Lead Measurement/Action Negative Lead
      C226A-12  VOLTAGE C218A-4 

    Is the voltage greater than 11 volts? 

    • Yes  : Go to  C4
    • No  : Go to C3 
  3. C3 CHECK FOR VOLTAGE TO THE SASM (STEERING ANGLE SENSOR MODULE) 
    • Measure:
      Positive Lead Measurement/Action Negative Lead
      C226A-12  VOLTAGE Ground

    Is the voltage greater than 11 volts? 

    • Yes  : REPAIR the ground circuit.
    • No  : REPAIR the illumination circuit.
  4. C4 CHECK FOR VOLTAGE TO THE STEERING WHEEL HARNESS AT THE CLOCKSPRING 
    • Connect SASM C226A  .

    • Depower the SRS  and remove the driver airbag.

      Refer to: DRIVER AIRBAG .

    • Disconnect Clockspring C218B  .
    • Measure:
      Positive Lead Measurement/Action Negative Lead
      C218B-7 (Clockspring Component Side) VOLTAGE C218B-10 (Clockspring Component Side)

    Is the voltage greater than 11 volts? 

    • Yes  : CONNECT clockspring C218B  .

      For LH  lower switch only, Go to  C6

      For multiple steering wheel switches, INSTALL a new steering wheel.

      Refer to: STEERING WHEEL .

    • No  : Go to C5 
  5. C5 CHECK THE CLOCKSPRING FOR AN OPEN 
    • Ignition OFF.
    • Remove the clockspring.

      Refer to: CLOCKSPRING .

    • Measure:
      Positive Lead Measurement/Action Negative Lead
      C218B-7 (Clockspring Component Side) OHM C218C-7 (Clockspring Component side)
    • Positive Lead Measurement/Action Negative Lead
      C218B-10 (Clockspring Component Side) OHM C218A-4 (Clockspring Component Side)

    Are the resistances less than 3 ohms? 

  6. C6 CHECK FOR VOLTAGE AT THE LH (LEFT-HAND) LOWER STEERING WHEEL SWITCH 
    • Turn the parking lamps off.
    • Ignition OFF.
    • Depower the SRS  and remove the driver airbag.

      Refer to: DRIVER AIRBAG .

    • Disconnect LH  Lower Steering Wheel Switch C2366  .
    • Ignition ON.
    • Turn the parking lamps on.
