DTC Descriptor

DTC B1295 07

- Steering Wheel Controls Group 2 Signal Circuit High Voltage

Diagnostic Fault Information

The body control module (BCM) supplies voltage to the steering wheel control switches and monitors the return signal. Each switch state is

associated to a set resistance value and when pressed a specific voltage drop occurs across the resistor unique to the switch. The BCM identifies the

switch selection and activates the feature.

Conditions for Running the DTC

* The system voltage is between 9-16 V.

* The ignition is ON.

Conditions for Setting the DTC

* The BCM detects a short to voltage on the signal circuit.

* The above condition is present for greater than 30 s.
