DTC DETECTING CONDITION





FAIL-SAFE FUNCTION
Sensor failure outside the ABS control cycle:
1. Only one wheel failure
Only the ABS, (TCS) function is inhibited. the ABS, (TCS) warning lamp is activated and the EBD warning lamp not activated.
2. More than two wheels failure
System down. both the ABS, (TCS) and the EBD function are inhibited and the ABS, (TCS) and the EBD warning lamps is activated. In this failure, the valve relay and all solenoids are prevented from being switched on.

Sensor failure inside the ABS control cycle:
1. One front wheel failure
Inhibit the ABS control of the failed-wheel and maintain the ABS control of normal wheel.
After the controller completes the ABS control, the ABS, (TCS) function is inhibited. the ABS, (TCS) warning lamp is activated and the EBD warning lamp not activated.
2. One rear wheel failure
Inhibit ABS control of both front wheels and the pressure of both rear wheels is decreased.
After the controller completes the ABS control, Only the ABS(,TCS) function is inhibited. the ABS, (TCS) warning lamp is activated and the EBD warning lamp not activated.
3. More than two wheels failure.
System down. both the ABS, (TCS) and the EBD function are inhibited and the ABS, (TCS) and the EBD warning lamps is activated. In this failure, the valve relay and all solenoids are prevented from being switched on.
