DTC | C1290, C1953 | Brake fluid pressure sensor system
DETECTION CONDITION | • C1290 ― The basic brake fluid pressure value, which is calculated in the DSC HU/CM while the system is not operated and the brake is not applied, exceeds the specified value. • C1953 ― The brake fluid pressure sensor signal voltage is continuously more than 3.29 V or less than 0.13 V for 100 ms or more.
POSSIBLE CAUSE | • Brake fluid pressure sensor malfunction in DSC HU/CM • Open or short circuit in the brake fluid pressure sensor circuit in DSC HU/CM

Diagnostic procedure

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