Toyota Tacoma 2015-2018 Service Manual: High Power Supply Voltage Malfunction (C1417)

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/TRAC 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.
