System Components
System Description
WHEEL SENSOR
The sensor unit consists of a gear-shaped sensor rotor and a sen-
sor element. The element contains a bar magnet around which a
coil is wound. The sensor is installed on the back of the brake rotor.
As the wheel rotates, the sensor generates a sine-wave pattern.
The frequency and voltage increase(s) as the rotating speed
increases.
CONTROL UNIT (built in ABS actuator and electric 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 motor 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 ABS will be deactivated by the
control unit, and the vehicle's brake system reverts to normal
operation. (For control unit layout, refer to ABS ACTUATOR AND
ELECTRIC UNIT, BR-34.)

. 1: If one or more wheels spin on a rough or slippery road for 40 seconds or more, the ABS warning lamp will illuminate. This does
not indicate a malfunction. Only in the case of the short-circuit (Code Nos. 26, 22, 32 and 36), after repair the ABS warning lamp
also illuminates when the ignition switch is turned ``ON''. In this case, drive the vehicle at speeds greater than 30 km/h (19 MPH)
for approximately 1 minute as speci®ed in ``SELF-DIAGNOSIS PROCEDURE'', BR-47. Check to ensure that the ABS warning
lamp goes out while the vehicle is being driven.
. 2: The trouble code ``57'', which refers to a low power supply voltage, does not indicate that the ABS control unit is malfunctioning.
Do not replace the ABS control unit with a new one.
. 3: The trouble code ``61'' can sometimes appear when the ABS motor is not properly grounded. If it appears, be sure to check the
condition of the ABS motor ground circuit connection.

Camshaft Position Sensor (CMPS) (PUMP)
The camshaft position sensor (PUMP) is located on the electronic
fuel injection pump.
The sensor consists of a permanent magnet, core and coil.
When engine is running, gap between sensor and drive shaft rotat-
ing plate will periodically change. Permeability near the sensor also
changes.
Due to the permeability change, the magnetic ¯ux near the core is
changed. Therefore, the voltage signal generated in the coil is
changed.
The ECM receives the voltage signal (6 pulses/2 engine revolu-
tions).
These signals are used for tachometer indication.

Electric Governor
The electric governor is built into the electronic fuel injection pump.
It moves the control sleeve to increase or decrease the amount of
fuel injected.
When current ¯ows through the coil, a magnetic force is produced,
rotating the rotor. The rotor shaft is installed to the control sleeve
via a ball pin which is eccentrically situated in relation to the rotor
shaft. With this arrangement, the control sleeve can be moved in
relation to rotor rotation.
The rotor's rotating angle is determined by a balanced condition of
magnetic force (generated by current ¯ow regulated by means of
the ECM) and tension of return spring (installed to rotor). The larger
the current ¯ow through the coil, the greater the rotor's rotating
angle. This means that the control sleeve moves to the right,
increasing the amount of fuel injected.
The ECM regulates the current ¯ow through the coil by changing
the duty ratio which controls the ON-OFF operation of the electric
governor grounding circuit.
