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 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 No.
