Circuit/System Testing
WARNING: This page is about a different car, the 2007 Chevrolet Monte Carlo and 2007 Chevrolet Impala. 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 switch.
- Ignition ON, measure for 10 volts or greater at the steering wheel 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, 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.
- If the circuit tests normal, test the component. If the component tests normal, replace the BCM.
