C14D5 | Accumulator Pressure Sensor Stuck |
DESCRIPTION
The accumulator pressure sensor is built into the brake booster with master cylinder assembly and detects the accumulator pressure.
If the skid control ECU (brake booster with master cylinder assembly) detects that the accumulator pressure sensor value is below the threshold, operation of the motor relay is requested and the pump motor built into the brake booster pump assembly operates.
DTC No. | Detection Item | INF Code | DTC Detection Condition | Trouble Area | Note |

C14D5 | Accumulator Pressure Sensor Stuck | 334 | When the pump motor is operating, the accumulator pressure sensor signal does not change for 14 seconds or more. | Skid control ECU (brake booster with master cylinder assembly) | Electronically controlled brake system DTC |
CAUTION / NOTICE / HINT
Note
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".
