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
