3. Ignition ON, verify that DTC C0280 54 is not set as a present DTC.
瀚慖f DTC C0280 54 is present, replace the K17 Electronic Brake Control Module (EBCM) and verify DTC does not reset. If the DTC
resets, replace the Q5 brake pressure modulator valve assembly.

Diagnostic Fault Information
Circuit/System Description
The yaw rate, lateral acceleration and longitudinal acceleration sensors are combined into one multi-axis acceleration sensor, external to the
electronic brake control module (EBCM). The EBCM supplies a 12 V reference voltage to the multi-axis acceleration sensor. The multi-axis
acceleration sensor communicates with the EBCM via the high speed controller area network (CAN) serial data circuit. The EBCM activates the
