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 at the cruise control on/off switch.
- Ignition ON, measure for 10 volts or greater at the cruise control supply voltage circuit.
- If less than the specified value, check for an open/high resistance or a short to ground on the cruise control supply voltage circuit.
- Ignition OFF, connect the harness connector at the cruise control on/off switch. Disconnect the harness connector at the cruise control set/cruise, resume/accelerate switch.
- Ignition ON, cruise on/off switch ON, measure for 10 volts or greater at the cruise control switch signal circuit.
- If less than the specified value, check for an open/high resistance or a short to ground on the cruise control switch signal circuit between the cruise on/off switch terminal 6 and the cruise control set/cruise, resume accelerate switch terminal 6 (UK3)/terminal 3 (non UK3). If the circuit tests normal, replace the cruise on/off switch assembly.
- Ignition OFF, test for an open/high resistance, a short to ground, or a short to voltage in the cruise control switch signal circuit.
- Test the component. If the circuits and the component tests are normal, replace the BCM.
