Circuit/System Testing

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 of the cruise control switch.
3. Ignition ON, measure for 10 volts or greater at the cruise control supply voltage circuit.
   • If less than 10 volts, check for an open/high resistance or for a short to ground on the cruise control supply voltage circuit.
4. Ignition OFF, test for an open, for a high resistance, for a short to ground, or for a short to voltage in the cruise control switch signal circuit.
5. Test the component. If the circuits and the component tests are normal, replace the BCM.
