Solenoid Circuit Shorted

NAME OF CODE:
LF Solenoid Circuit Shorted
RF Solenoid Circuit Shorted
LR Solenoid Circuit Shorted
RR Solenoid Circuit Shorted

WHEN MONITORED:
Any time the system relay is energized, system relay output voltage must be above 9 volts and below 20 volts. The solenoid channels are tested every minute when not in Anti-lock Brake System (ABS) cycling, and every 620 ms when in cycling. Each solenoid is tested separately at 5 ms intervals, with a complete test taking 20 ms to complete.

SET CONDITION:
The modulator is a group of four solenoid valves controlled by the Controller, Anti-lock Brake (CAB) to modulate brake pressure during ABS control. One solenoid valve controls each wheel. Solenoid power is supplied through the CAB's internal solenoid drivers. The CAB receives power for the solenoids from the system relay located in the relay box. The CAB monitors each driver circuit when it is on and will store a trouble code if the solenoid voltage is below a calculated threshold referenced to the system relay output voltage.

POSSIBLE CAUSES:
- Decay solenoid control circuit shorted to ground
- Shorted solenoid coil
- Failed solenoid driver
