Pinpoint Test C : C0044:28, C0044:49, C0044:64: Notes

Diagnostic Overview 

C0044:28, C0044:49, C0044:64 

Refer to Vehicle Dynamic Systems for schematic and connector information.

Normal Operation and Fault Conditions 

The ABS module uses internal pressure sensors to determine correct system operation by monitoring internal HCU hydraulic pressures. The pressure sensors are internal to the HCU and cannot be serviced separately. Unintentional brake fluid pressure present when the ABS module is expecting no brake fluid pressure can set this fault.

DTC Fault Trigger Conditions 

DTC Description Fault Trigger Conditions
C0044:28 Brake Pressure Sensor A: Signal Bias Level Out of Range / Zero Adjustment Failure These DTCs set in continuous memory and on-demand if the brake pressure sensor signals do not match. These faults may be set by either an internal ABS module failure or a pressure sensor failure.
C0044:49 Brake Pressure Sensor A: Internal Electronic Failure
C0044:64 Brake Pressure Sensor A: Signal Plausibility Failure
