The control unit contains a monitoring circuit to detect any internal faults in the control unit and any electrical faults in the sensors, hydraulic modulator or signaling system.
If a fault occurs, the control unit disengages the ABS and illuminates a warning light. When the warning light comes on, a complete fault tracing procedure should be followed. The fault tracing procedure assumes that the standard braking system is fully operational.
