A short to ground or open is detected signal circuit.

C012D 5A or C120A

The boost pressure being commanded is not being achieved.

C012D OF or C12BE

Signal is erratic and changes faster than physically allowed.

Action Taken When the DTC Sets

* The EBCM disables the ABS and vehicle stability enhancement system (VSES) for the duration of the ignition cycle.

Circuit/System Verification

Perform Brake Pedal Travel Measurement and Inspection (Non-Hybrid) (See: Brakes and Traction Control/Hydraulic System/Testing and

Inspection/Component Tests and General Diagnostics/Brake Pedal Travel Measurement and Inspection (Non-Hybrid))Brake Pedal Travel

Measurement and Inspection (Two-mode Hybrid) (See: Brakes and Traction Control/Hydraulic System/Testing and Inspection/Component Tests

and General Diagnostics/Brake Pedal Travel Measurement and Inspection (Two-Mode Hybrid))

Circuit/System Testing

1. Verify that no other DTCs are set.

瀚慖f DTC is set, refer to Diagnostic Trouble Code (DTC) List - Vehicle (See: Diagnostic Trouble Code Descriptions/Diagnostic Trouble

Code (DTC) List - Vehicle).

2. Using a scan tool, perform the EBCM, module setup, and EBCM Relearn.

3. Verify that DTC C012D, C120A, C128A, C128D, C12BC, C12BD, or C12BE is not set.

瀚慖f DTC is set replace brake pressure modulator valve (BPMV) assembly. If the DTC resets, replace the EBCM.
