Circuit/System Testing
WARNING: This page is about a different car, the 2007 Pontiac G5 Pursuit, 2007 Pontiac G5, and 2007 Chevrolet Cobalt. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
Refer to SIR Caution
.
Disable the inflatable restraint steering wheel module when performing this diagnostic. Refer to SIR Disabling and Enabling .
- Ignition OFF, remove the inflatable restraint steering wheel module. Refer to Inflatable Restraint Steering Wheel Module Replacement .
- Disconnect the harness connector of the cruise control on/off switch.
- 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.
- Ignition OFF, disconnect the harness connector of the set/cruise, resume/accelerate switch. Test for an open/high resistance, a short to ground, or a short to voltage in the cruise control switch signal circuit between the BCM and the set/cruise, resume/accelerate switch.
- Test for an open/high resistance, a short to ground, or a short to voltage in the cruise control switch signal circuit between the cruise control on/off switch and the set/cruise, resume/accelerate switch.
- Test the component. If the circuits and the component tests are normal, replace the BCM.
