Diagnostic Fault Information

Circuit/System Description

The electronic brake control module (EBCM) supplies a shared 5 volt reference to the brake master cylinder piston position sensor, steering angle

sensor and brake master cylinder piston position sensor.

Conditions for Running the DTC

* Ignition ON.

* The ignition voltage is greater than 10 volts.

Conditions for Setting the DTC

The EBCM detects the voltage on the 5 V reference circuit to the brake master cylinder piston position sensor, steering angle sensor and brake

master cylinder piston position sensor is less than 4.8 V or greater than 5.2 V.

Action Taken When the DTC Sets

* The EBCM disables the antilock brake system (ABS), traction control and the vehicle stability enhancement system for the duration of the

ignition cycle.

* A driver information center message and/or a warning indicator may be displayed.

Conditions for Clearing the DTC

* The condition for the DTC is no longer present.

* The EBCM clears the history DTC when a current DTC is not detected in 40 consecutive drive cycles.
