DTC C0044:1C, C0044:28, C0044:49, C0044:54, C0044:56, C0044:64, C0044:84 OR C0044:85 (DSC HU/CM) DETECTION CONDITION AND POSSIBLE CAUSE
| System malfunction location |
Brake fluid pressure sensor |
| Detection condition |
- C0044:1C
- The DSC HU/CM detects that the supply voltage to the brake fluid pressure sensor is outside of the specification.
- C0044:28
- The DSC HU/CM detects that the offset amount of the brake fluid pressure signal is outside of the specification.
- C0044:49
- The DSC HU/CM detects any of the following conditions.
- Brake fluid pressure sensor supply voltage malfunction
- Brake fluid pressure sensor internal malfunction or poor functioning
- C0044:54
- The DSC HU/CM detects that the brake fluid pressure sensor initialization was not implemented.
- C0044:56
- The DSC HU/CM and brake fluid pressure sensor configuration information do not match.
- C0044:64
- The DSC HU/CM detects a non-conformity in any of the following signals.
- Brake fluid pressure signals of 2 systems received from brake fluid pressure sensor
- Brake fluid temperature signals of 2 systems received from brake fluid pressure sensor
- C0044:84
- The DSC HU/CM detects that the brake fluid pressure signal of 1 out of the 2 brake fluid pressure sensors is the specification or less.
- C0044:85
- The DSC HU/CM detects that the brake fluid pressure signal of 1 out of the 2 brake fluid pressure sensors is the specification or more.

| Fail-safe |
Refer to "DTC Table" and "Fail-safe Function Malfunction Contents Table". (See DTC TABLE [DSC HU/CM (US)] .) |
| 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
