VEHICLE STABILITY CONTROL SYSTEM, Diagnostic DTC:C1417
| DTC Code | DTC Name |
|---|---|
| C1417 | High Power Supply Voltage Malfunction |
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 +BS 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 +BS terminal voltage returns to normal.
