Circuit/System Verification
1. Using a scan tool, perform the EBCM, Module Setup, EBCM Relearn.
2. Verify that DTC C012C, C121A, C128C, C128F, C12B9, C12BA, C12BB or C12F7 is not set.
瀚慖f the DTC is set replace brake pressure modulator valve assembly. If the DTC resets, replace the EBCM.

Diagnostic Fault Information
Circuit/System Description
The electronic brake control module (EBCM) uses input from the brake master cylinder piston position sensor and the brake switch to determine
when the brake pedal is being applied and with how much force. These inputs are used to determine the driver's braking intent which is used to the
control amount of pressure applied to the wheels.
