### Circuit/System Description

The electronic brake control module (EBCM) commands the solenoid relay ON or OFF to open or close the valves in the BPMV.

### Conditions for Running the DTC

Ignition ON.

### Conditions for Setting the DTC

• | The EBCM detects no change in voltage when commanding the solenoid valves ON.

• | The EBCM detects no change in voltage when commanding the solenoid valves OFF.

### Action Taken When the DTC Sets

• | The EBCM disables the antilock brake system (ABS),traction control (TC),vehicle stability control for the duration of the ignition cycle.

• | If equipped the EBCM sends a serial data message to illuminate the warning indicator/message.

### 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 100 consecutive drive cycles.
