DESCRIPTION
If a malfunction is detected in the power supply circuit, the skid control ECU (brake actuator assembly) stores this DTC and the fail-safe function prohibits ABS operation.
This DTC is stored when the IG1 terminal voltage deviates from the DTC detection condition due to a malfunction in the power supply or charging circuit such as the battery or generator circuit, etc.
The DTC is canceled when the IG1 terminal voltage returns to normal.
DTC No. | Detection Item | DTC Detection Condition | Trouble Area |
---|---|---|---|
C1417 | High Power Supply Voltage Malfunction | The IG1 terminal voltage is 17.4 V or more for 0.8 seconds or more. |
