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 (housed in the 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 cancelled 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 more for 0.8 seconds or more.

  • ECU-IG NO. 1 fuse

  • Battery

  • Charging system

  • Power source circuit

  • Internal power supply circuit of the skid control ECU
