| MONITOR DESCRIPTION
The
skid control ECU (brake booster with master cylinder assembly) monitors
the drive voltage and current of the ABS holding solenoid and ABS
reduction solenoid. Based on the monitored information, if any of the
following abnormal conditions are detected, the MIL is illuminated and a
DTC is stored.
- A flyback circuit malfunction is detected.
- A malfunction of the current monitor is detected.
- An open circuit in the holding valve is detected.
- When the monitored current value increases to a value that is not possible when normal.
- A current leakage is detected.
- Output malfunction is detected when there is a solenoid off command.
- An open circuit in the decrease pressure valve is detected.
