- Brake Boost Solenoid Valve Circuit

DTC C012F 0E

- Brake Boost Solenoid Valve Circuit Shorted

DTC C12A7

- Brake Boost Solenoid Valve Circuit Performance

DTC C12DC

Circuit/System Description

The electronic brake control module (EBCM) uses input from the boost pressure sensor for more accurate control during brake and vehicle stability

enhancement system (VSES) event. The boost pressure sensor is internal to the brake pressure modulator valve (BPMV).

Conditions for Running the DTC

* The ignition is ON.

* Ignition voltage is greater than 10 volts.

Conditions for Setting the DTC

C012F 00, C12A7, C12DC

Solonoid feedback current greater than 25% of commanded current.

C012F 0E, C12DD

Solonoid feedback current greater than 50% of requested current.

Action Taken When the DTC Sets

* The EBCM disables the ABS/traction control system (TCS)/vehicle stability enhancement system (VSES) for the duration of the ignition

cycle.

* A DIC 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.
