DTC C1417 High Power Supply Voltage Malfunction

DESCRIPTION

If a malfunction is detected in the power supply circuit, the skid control ECU (master cylinder solenoid) 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 generator circuit, etc.


This DTC is cleared when the IG1 terminal voltage returns to normal.

DTC CodeDTC Detection ConditionTrouble Area
C1417The IG1 terminal voltage is 17.4 V or higher for 0.8 seconds or more.
Charging system
Power source circuit
Internal power supply circuit of the skid control ECU (master cylinder solenoid)

WIRING DIAGRAM

Refer to DTC C1241 ().


INSPECTION PROCEDURE

  • NOTICE:
  • After replacing the master cylinder solenoid, perform zero point calibration ().
1.CHECK HARNESS AND CONNECTOR (IG1 TERMINAL)

Disconnect the skid control ECU (master cylinder solenoid) connector.
