DTC C1417 High Power Supply Voltage Malfunction


DESCRIPTION

If a malfunction is detected in the power supply circuit, the skid control ECU (housed in the brake actuator assembly) stores this DTC and the fail-safe function prohibits ABS/VSC/TRC 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 alternator circuit, etc.
This DTC is canceled when the IG1 terminal voltage returns to normal.

DTC Code
DTC Detection Condition
Trouble Area
C1417
The IG1 terminal voltage is 17.4 V or higher for 1 second or more.
  1. ECU-IG1 fuse
  2. Battery
  3. Charging system
  4. Power source circuit
  5. Internal power supply circuit of the skid control ECU
