DTC C1365/54: Accumulator Pressure Sensor Malfunction: Description
The accumulator pressure sensor is built into the brake actuator.
The skid control ECU detects the accumulator pressure from the data sent from the accumulator pressure sensor, and then runs and stops the pump motor by operating the motor relay.
DTCs may be output if the accumulator pressure drops due to frequent braking (this is not a malfunction).
| DTC Code | INF Code | DTC Detection Condition | Trouble Area |
|---|---|---|---|
| C1365/54 | 211 | Sensor power 1 (VCM) voltage is 4.7 V or less or 5.3 V or more for at least 0.05 seconds. |
|
| ↑ | 212 | Accumulator pressure sensor output voltage (PAC1) is less than 0.25 V or 4.53 V or more for at least 0.05 seconds. | ↑ |
| ↑ | 214 | While the motor is off, the total of the wheel cylinder pressure sensor values of all 4 wheels increases but the accumulator pressure changes very little for 0.5 seconds or more. | ↑ |
| ↑ | 215 | Accumulator pressure sensor output voltage (PAC1) is stuck at 4.53 V or less. | ↑ |
