DTC C0273/13 Open in ABS Motor Relay Circuit

DESCRIPTION

DTC Detecting Condition:

- The ABS motor relays consist of 2 relays and are included in the ABS R/B.
- The ABS MTR CUT relay is turned on after turning the ignition switch to the ON position. If the DTCs in the ABS pump motor circuit are memorized, the ABS MTR CUT relay cuts off the power supply to the ABS MTR relay and performs the fail safe.
- While any of the ABS, BA, TRAC and VSC is operating, the skid control ECU (included in the ABS and TRACTION actuator) turns the ABS MTR relay on to operate the actuator pump motor.
- If the voltage applied to the ABS motor relays (BM) drops below the condition that detects the DTCs due to the shortage of the battery or alternator output, the DTCs may be memorized.
