Altima XE L4-2.4L (KA24DE) (1999)
Electronic Brake Control Module: Description and Operation
CONTROL UNIT
The control unit computes the wheel rotating speed by the signal current sent from the sensor. Then it supplies a DC current to the actuator solenoid
valve. It also controls ON-OFF operation of the valve relay and pump relay. If any electrical malfunction should be detected in the system, the control
unit causes the warning lamp to light up. In this condition, the Anti-lock Brake System (ABS) will be deactivated by the control unit, and the vehicle's
braking system reverts to normal operation.
