C05401C |
Brake Pressure Sensor "A" Circuit Voltage Out of Range |
The voltage of the master cylinder pressure sensor signal is less than 0.129 V or more than 3.29 V for 0.1 seconds or more. |
Skid control ECU (brake actuator assembly) |
Does not come on |
Brake/EPB |
Output ECU: Skid control ECU (brake actuator assembly) |
|
C054028 |
Brake Pressure Sensor "A" Signal Bias Level Out of Range / Zero Adjustment Failure |
When the stop light switch assembly is off, the zero point of the master cylinder pressure sensor is less than -1.5 MPa (-15.3 kgf/cm2, -218 psi) or more than 1.5 MPa (15.3 kgf/cm2, 218 psi). |
Skid control ECU (brake actuator assembly) |
Comes on |
Brake/EPB |
|
|
C054029 |
Brake Pressure Sensor "A" Signal Invalid |
A master cylinder pressure sensor internal malfunction is detected by the self-diagnosis function of the master cylinder pressure sensor circuit. |
Skid control ECU (brake actuator assembly) |
Comes on |
Brake/EPB |
|
|
C054031 |
Brake Pressure Sensor "A" No Signal |
Signals from the master cylinder pressure sensor cannot be received and the input value from the signal line is outside of a certain range. |
Skid control ECU (brake actuator assembly) |
Comes on |
Brake/EPB |
|
|
C054049 |
Brake Pressure Sensor "A" Internal Electronic Failure |
An internal malfunction of the master cylinder pressure sensor is detected during the self-test. |
Skid control ECU (brake actuator assembly) |
Does not come on |
Brake/EPB |
Output ECU: Skid control ECU (brake actuator assembly) |
|
C054096 |
Brake Pressure Sensor "A" Component Internal Failure |
The master cylinder pressure sensor value is outside of a certain range or an internal malfunction is detected. |
Skid control ECU (brake actuator assembly) |

MONITOR DESCRIPTION
C0540 (Case 1 and 2):
- When the pressure valve is at a certain value for a certain amount of time, the skid control ECU (brake actuator assembly) illuminates the MIL and stores this DTC.
C0540 (Case 3 and 4):
- If the self-diagnosis function detects a pressure sensor internal malfunction, the skid control ECU (brake actuator assembly) illuminates the MIL and stores this DTC.
C0540 (Case 5 and 6):
- If the self-diagnosis function detects a pressure sensor internal malfunction for a certain amount of time, the skid control ECU (brake actuator assembly) illuminates the MIL and stores this DTC.
C0541:
- When the stop light switch assembly is off and the offset value of the master cylinder pressure is a certain value or more, the skid control ECU (brake actuator assembly) illuminates the MIL and stores this DTC.

CONFIRMATION DRIVING PATTERN
NOTICE:
When performing the normal judgment procedure, make sure that the driver door is closed and is not opened at any time during the procedure.
HINT:
- After repair has been completed, clear the DTC and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.
- When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.
- Connect the GTS to the DLC3.
- Turn the ignition switch to ON and turn the GTS on.
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
- Turn the ignition switch off.
- Turn the ignition switch to ON (READY) and turn the GTS on.
-
Wait for 5 seconds or more. [*]
HINT:
[*]: Normal judgment procedure.
The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
-
Enter the following menus: Chassis / Brake/EPB* / Utility / All Readiness.
*: Electric Parking Brake System
-
Check the DTC judgment result.
HINT:
- If the judgment result shows NORMAL, the system is normal.
- If the judgment result shows ABNORMAL, the system has a malfunction.
- If the judgment result shows INCOMPLETE, perform driving pattern again.
