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.
