DTC 13

DTC C0273/13 Open in ABS Motor Relay Circuit

DTC C0274/14 Short to B+ in ABS Motor Relay Circuit

DTC C1361/91 Short Circuit in ABS Motor Fail Safe Relay Circuit

DESCRIPTION
If a DTC of the motor line is stored, the ABS MOTOR2 relay cuts off the power supply to the ABS MOTOR1 relay and performs fail-safe. While any of the ABS, TRAC, VSC, or BA is operating, the skid control ECU (housed in the actuator assembly) turns the ABS MOTOR2 relay on and activates the pump motor in the ABS and TRACTION actuator. This code may be stored if the motor relay (+BM) voltage becomes lower than the DTC detecting condition due to insufficient output from the battery or alternator.
