Circuit/System Description

The electronic brake control module (EBCM) uses input from the master cylinder pressure sensor for more accurate control during a vehicle

stability enhancement system event. The master cylinder pressure sensor is internal to the brake pressure modulator valve.

Conditions for Running the DTC

* The ignition is ON.

* Ignition voltage is greater than 10 volts.

* The brake pedal is not applied.

Conditions for Setting the DTC

C012A 00, C128E or C128B

Internal sensor failure is detected.

C012A 11

Improper relearn performed

C012A 01 or C12B3

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

C012A 06 or C12B2

A short to ground or open is detected signal circuit.

C012A OF or C12B4

Signal is erratic and changes faster than physically allowed.

Action Taken When the DTC Sets

* The EBCM disables the ABS and 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 setting the DTC is no longer present.

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