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.



Repair Instructions



Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.



* Brake Pressure Modulator Valve Replacement (See: Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Hydraulic



Control Assembly - Antilock Brakes/Service and Repair/Brake Pressure Modulator Valve Replacement)



* Control Module References (See: Testing and Inspection/Programming and Relearning) for EBCM replacement, programming and setup

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
