CAUTION: Refer to SIR Caution .

Disable the inflatable restraint steering wheel module when performing this diagnostic. Refer to SIR Disabling and Enabling .

  1. Ignition OFF, remove the inflatable restraint steering wheel module. Refer to Inflatable Restraint Steering Wheel Module Replacement .
  2. Disconnect the harness connector at the multifunction switch.
  3. Ignition ON, measure for 10 volts or greater at the 12-volt reference circuit.
    • If less than the specified value, check for an open/high resistance or a short to ground on the 12-volt reference circuit.
  4. Test the cruise control switch signal circuit for an open/high resistance, a short to ground or a short to voltage.
  5. If the circuits test normal, test the component. If the component tests normal, replace the BCM.
