Circuit/System Description

The electronic brake control module (EBCM) uses input from the regenerative axle pressure sensor for more accurate control during a brake and

vehicle stability enhancement system (VSES) event. The regenerative axle pressure sensor is internal to the brake pressure modulator valve

assembly.

Conditions for Running the DTC

* Ignition ON.

* Ignition voltage is greater than 10 volts.

Conditions for Setting the DTC

C128F, C12F7, C121A, C012C 11 or C128C

Internal sensor failure is detected.

C012C 01 or C12BA

A short to battery is detected on the sensor signal circuit.

C012C 06 or C12B9

A short to ground or open is detected signal circuit.

C012C 0F or C12BB

Signal is erratic and changes faster than physically allowed.

Action Taken When the DTC Sets

A DIC message and/or a warning indicator may be displayed.
