DTC |
C14C3 |
Servo Pressure Sensor Zero Point Malfunction |
DESCRIPTION
The Servo pressure sensor detects and outputs the brake fluid pressure generated in the wheel cylinder according to the vehicle condition to the skid control ECU (brake booster with master cylinder assembly).

C14C3 |
Servo Pressure Sensor Zero Point Malfunction |
424 |
When the brake pedal is not depressed, the servo pressure sensor output value is -0.63 MPa (-6.4 kgf/cm2, -91.4 psi) or less or 1.53 MPa (15.6 kgf/cm2, 222 psi) or more for 3 seconds or more. |
Skid control ECU (brake booster with master cylinder assembly) |
Electronically controlled brake system DTC |
CAUTION / NOTICE / HINT
NOTICE:
After replacing the skid control ECU (brake booster with master cylinder assembly), perform linear solenoid valve offset learning, ABS holding solenoid valve learning, yaw rate and acceleration sensor zero point calibration and system information memorization after performing "Reset Memory".

Servo Pressure |
Pressure value of servo |

Brake pedal released: 0.00 to 2.10 MPa |
Brake pedal is being depressed: Changes in proportion to the depression force of the brake pedal |

Servo Pressure |
(b) Check that the servo pressure sensor output value is within 0.00 to 1.53 MPa when the brake pedal not depressed.
OK:
The servo pressure sensor output value is within 0.00 to 1.53 MPa.
HINT:
If the servo pressure sensor output value is within 0.00 to 1.53 MPa, the skid control ECU (brake booster with master cylinder assembly) automatically performs zero point calibration every time the power switch is turned on (IG).
Therefore, if the servo pressure sensor output value is not within 0.00 to 1.53 MPa, replace the skid control ECU (brake booster with master cylinder assembly) with a new one.

2. |
RECONFIRM DTC |
(a) Clear the DTCs.
Chassis > ABS/VSC/TRAC > Clear DTCs
(b) Turn the power switch off.
(c) Turn the power switch on (IG).
(d) Check if the same DTC is output.
Chassis > ABS/VSC/TRAC > Trouble Codes
HINT:
Even if the DTC is cleared, it will immediately be output again if the servo pressure sensor zero point malfunction remains.
