### Circuit/System Description

The solenoid relay, located within the electronic brake control module (EBCM), supplies battery voltage to all of the valve solenoids. The Electronic Brake Control Module (EBCM) controls the valve function by grounding the solenoid circuit when necessary.

### Conditions for Running the DTC

Ignition ON.

### Conditions for Setting the DTC

A short to voltage, open or ground is detected on the solenoids within the brake modulator assembly.

### Action Taken When the DTC Sets

• | The EBCM disables the Antilock Brake System (ABS)/Traction Control System (TCS)/Electronic Stability Control (ESP)/Electronic Brake Distribution (EBD) for the duration of the ignition cycle.

• | A DIC message and/or 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 100 consecutive drive cycles.

### Diagnostic Aids

The TCS solenoid is integral to the brake modulator assembly/EBCM. The brake fluid pressure sensor is not serviceable independently.
