.
- Ignition OFF, disconnect the harness connector at the audio steering wheel control switch.
- Ignition ON, test for 10-12 volts between the voltage circuit and ground at the switch harness connector.
- If less than 10 volts, test the voltage circuit for a short to ground or an open/high resistance. If circuit test normal, replace the BCM.
- Test for 0-0.5 volts between the signal circuit and ground at the switch harness connector.
- If greater than 0.5 volts, test the signal circuit for short to voltage. If circuit test normal, replace BCM.
- Test for 10-12 volts between the voltage circuit and the signal circuit at the switch harness connector.
- If less than 10 volts, test the signal circuit for an open/high resistance. If circuit test normal, replace the BCM.
- Ignition OFF, disconnect the harness connector at the BCM.
- Test for infinite resistance between the signal circuit and ground at the harness connector.
- If less than infinite resistance, test the signal circuit for a short to ground. If circuit test normal, replace the BCM.
- If all circuits test normal, test or replace switch.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
