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.
