when the wheel speed drops sharply below the vehicle speed, the inlet valve closes to retain the caliper fluid pressure
When the wheel speed drops further, the outlet valve opens momentarily to reduce the caliper fluid pressure. The pump
motor starts at this time.
As the wheel speed is restored, the inlet valve opens momentarily to increase the caliper fluid pressure.
Wheel SensoJ
The wheel sensors are the magnetic contactless type
As the gear pulser teeth rotate past the wheel sensor's magnetic coil, AC current is generated The AC frequency changes
in accordance with the wheel speed. The ABS control unit detects the wheel sensor signal frequency and thereby detects
the wheel speed.
There are four wheel sensors, one for each wheel
The gear pulser has 50 teeth.

Kickback
1. The motor operates when the ABS is functioning, and the fluid in the reservoir is forced out to the master cylinder
causing kickback at the brake pedal.
2. TheABScontrol unit operates the solenoid valve when the brake pedal is released afterthe initial diagnosis Youmay
hear the faint solenoid valve operation sound at this time. but it is normal.
Pump Motor
1. The pump motor operates when the ABS is functioning
2. The ABS control unit checks the pump motor operation during acceleration. You may hear the faint operation sound
at this time. but it is normal.
Brake Fluid Replacament/Air Blsading
1. Brake fluid replacement and air bleeding procedures are the same as for conventional brakes
Troubleshooting
1. The troubleshooting flowcharts explain the procedures on the assumption that the cause of the problem is still pre-
sent and the ABS indicator light is still on.
Note that troubleshooting following the flowchart when the ABS indicator light does not come on can result in incor-
rect judgment.
2. Ouestion the customer about the conditions when the problem occurred, and try to reproduce the same conditions
for troubleshooting.
self,diagnosis is made at various times such as the initial diagnosis, except ABS control. during ABS control, during
acceleraiion, during the specified vehicle speed, etc. Therefore, the symptom cannot be checked unless the check
conditions match with the problem conditions
3. When the ABS indicator light does not come on during the test drive, but the troubleshooting is performed based on
the DTC, check for the loose connectors. poor contact of the terminals, etc, before troubleshooting.
4. After troubleshooting, erase the DTC and test-drive the car. Be sure that the ABS indicator light does not come on.
5. The connector illustrations show the female connectors with a single outline and the male connectors with a double
ouflrne.
6. The connector terminal cavities containing female terminals are always numbered by looking at the connector from
the wire side. and the cavities containing male terminals are always numbered by looking at the connector from the
terminal side.

2.
Connect the SCS service connector to the service check connector inside the passenger's side kick panel.
Depress the brake pedal.
Turn the ignition switch oN (ll) while holding the brake pedal, but do not start the engine. The ABS indicator light
goes off after two seconds.
After the indicator light goes off, release the brake pedal The indicator lightcomeson after four seconds
After the indicator light comes on, depress the brake pedal again. The indicator light goes off again after four sec-
onds. The brake pedal is still depressed.

6. After the jndicator light goes off, release the brake pedal again'
7. After four seconds, the indicator light blinks twice for 0 3 second and the DTC is erased
8. Confirm the DTC indication, and check that the DTC was erased
NOTE: Always maintain these steps. lf you disconnect the scs service connector and/or fail to operate the brake pedal
according to the indicator light indication, the DTC will not be erased
Conditions for DTC erasure
o The vehicle is stopped.
. The SCS service connector is connected before the ignition switch is turned ON {ll)
. The brake pedal is depressed before the ignition switch is turned ON (ll)'
. The SCS service connector remains connected during this procedure
The DTC erasure stops and ABS control unit executes the software lunction it at least one ot the following conditions is
satisfied:
