Circuit/System Testing

  1. Ignition OFF, remove the inflatable restraint steering wheel module. Refer to Inflatable Restraint Steering Wheel Module Replacement .
  2. Disconnect the harness connector of the steering wheel controls switch - left.
  3. Ignition ON, test for 10 volts or greater between the steering wheel control supply voltage circuit terminal 1 and ground.
    • If less than 10 volts, check for an open/high resistance or for a short to ground on the steering wheel control supply voltage circuit. If the circuit tests normal, replace the BCM.
  4. Ignition ON, verify that a test lamp illuminates between B+ and the cruise control switch signal circuit terminal 3.
    • If the test lamp does not illuminate, test the cruise control switch signal circuit for an open/high resistance. If the circuit tests normal, replace the BCM.
  5. Ignition OFF, disconnect the harness connector C1 at the BCM.
  6. Measure for 0 volts between the cruise control switch signal circuit terminal 3 and ground.
    • If greater than the specified value, test the cruise control switch signal circuit for a short to voltage.
  7. If all circuits test normal, test the component. If the circuits and the component tests are normal, replace the BCM.
