DTC
C0044:01, C0044:28, C0044:54, C0044:64
Brake fluid pressure sensor
DETECTION CONDITION
•  C0044:01
―  The voltage value from the brake fluid pressure sensor is not within specification.
•  C0044:28, C0044:64
―  The pressure from the brake fluid pressure sensor is not within specification.
•  C0044:54
―   The brake fluid pressure sensor detects the initialization procedure has not been perform.
POSSIBLE CAUSE
•  The initialization procedure for the brake fluid pressure sensor has not been performed.
•  Brake fluid pressure sensor malfunction
•  Open or short circuit in the brake fluid pressure sensor circuit in DSC HU/CM

Diagnostic procedure

STEP

INSPECTION

ACTION
1
VERIFY INITIALIZATION PROCEDURE
•  Has the brake fluid pressure sensor initialization procedure been performed?
Yes
Go to the next step.
No
Perform the brake fluid pressure sensor initialization procedure, then go to the next step.
(See DSC SENSOR INITIALIZATION PROCEDURE.)
2
VERIFY NO ABNORMALITY ON BRAKE FLUID PRESSURE SENSOR
•  Clear the DTCs from the memory.
•  Start the engine and drive the vehicle at 10 km/h {6.2 mph} or more.
•  Are the same DTCs present?
Yes
Replace the DSC HU/CM, then go to the next step.
(See DSC HU/CM REMOVAL/INSTALLATION.)
No
Go to the next step.
3
VERIFY THAT NO OTHER DTCS ARE PRESENT
•  Are any other DTCs output?
Yes
Go to the applicable DTC inspection.
(See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)].)
No
DTC troubleshooting completed.
