DTC C0278 OPEN CIRCUIT IN ABS SOLENOID RELAY CIRCUIT

CIRCUIT DESCRIPTION

DTC Detecting Condition:

This relay supplies power to each ABS solenoid. Immediately after the ignition switch is turned to the ON position, the relay turns on if the solenoid is determined to be normal as a result of self-diagnosis during initial check.

The relay turns off if an open/short is detected.

If the voltage supplied to the motor relay (+BS) is below the DTC detection threshold due to battery/alternator shortage, the DTCs may be stored.
