SENSOR ROTOR
Removal
1. Remove the drive shaft and rear wheel hub. Refer to FA, RA
section (ªDrive Shaftº, FRONT AXLEº and ªWheel Hubº,
REAR AXLEº).
2. Remove the sensor rotor using suitable puller, drift and bear-
ing replacer.
Installation
Install the sensor rotor. For front sensor rotor, use hammer and
wooden block. For rear sensor rotor, use suitable drift and press.
lAlways replace sensor rotor with new one.
lEnsure sensor rotor is completely flush with surface indicated
on drive shaft.
lPay attention to the flush position of rear sensor rotor as
shown in figure.

1. Disconnect battery cable.
2. Drain brake fluid. Refer to BR-7
3. Unlock the slider then disconnect the electrical harness con-
nectors from ABS control unit.
4. Identify each brake pipe with corresponding actuator port
hole and mark them accordingly.
5. Disconnect brake pipes and move them away from actuator.
Do not force brake pipes so as to kink them or bend them
excessively.
Ensure that brake fluid does not come into contact with
any parts.
6. Loosen/remove mounting nuts between actuator and
bracket.
CAUTION:
After installation, pay attention to the following points:
lRefill brake fluid and bleed air. Refer to ªCHECK AND
ADJUSTMENTº, BR-7 and ªBLEEDING BRAKE
SYSTEMº, BR-8, respectively.
lThe installation procedure is as follows:
1. Install actuator on bracket without tightening fixings.
2. Assemble brake tubes to actuator without tightening tube
nuts. Ensure that correct tubes are connected to each port.
3. Fully tighten actuator and bracket fixings to specified torque.
4. Fully tighten flare nuts to specified torque, BR-10.
5. Secure ABS control unit harness connector and battery
cable.

How to Perform Trouble Diagnoses for Quick
and Accurate Repair
INTRODUCTION
The ABS system has an electronic control unit to control major
braking functions. The control unit accepts input signals from
sensors and utilises the data to instantly drive the actuators. It is
essential that both input and output signals are correct and
stable. It is also important to check for conventional problems:
such as air leaks in booster lines, lack of brake fluid, or other
problems with the brake system.
It is much more difficult to diagnose a problem that occurs inter-
mittently rather than catastrophically. Most intermittent problems
are caused by poor electric connections or faulty wiring. In this
case, careful checking of suspicious circuits may help prevent
the unnecessary replacement of good parts.
A visual check may not be sufficient to find the cause of the
problems, so a road test should also be performed.
Before undertaking actual checks, take just a few minutes to talk
with a customer who approaches with a ABS complaint. The
customer is a very good source of information on such problems;
especially intermittent ones. Through the talks with the customer,
find out what symptoms are present and under what conditions
they occur.
Start your diagnosis by looking for ªconventionalº problems first.
This is one of the best ways to troubleshoot brake problems on
an ABS controlled vehicle.

Self-diagnosis (Only models with data link
connector terminal No. 8)
FUNCTION
lWhen a problem occurs in the ABS, the warning lamp on the
instrument panel comes on. To start the self-diagnostic
results mode, ground the self-diagnostic (check) terminal
located on ªData Link Connector for CONSULT-IIº. The loca-
tion of the malfunction is indicated by the warning lamp flash-
ing.
SELF-DIAGNOSIS PROCEDURE
Drive vehicle over 30 km/h (19 mph) for at
least one minute.
Turn ignition switch to the ªLOCKº position.
Ground terminal ª8º of ªDATA LINK CON-
NECTOR for CONSULT-IIº with a suitable
harness.
Turn ignition switch to ªONº position while
grounding terminal ª8º.
Do not depress brake pedal.
After 3.0 seconds, the warning lamp starts
flashing to indicate the malfunction code
No. (See NOTE.)
Verify the location of the malfunction with
the malfunction code chart. Refer to BR-69.
Then make the necessary repairs following
the diagnostic procedures.
After the malfunctions are repaired, erase
the malfunction codes stored in the control
unit. Refer to BR-68.
Rerun the self-diagnostic results mode to
verify that the malfunction codes have been
erased.
NOTE: The indication ter-
minates after five
minutes.
However, when the
ignition switch is
turned from off to
on, the indication
starts flashing
again. Disconnect the check terminal from the
ground. The self-diagnostic results mode is
now complete.

CONSULT-II Inspection Procedure
SELF-DIAGNOSIS PROCEDURE
1) Turn ignition switch to the ªLOCKº
position.
2) Connect CONSULT-II to Data Link
Connector.
1) Start engine.
2) Drive vehicle over 30 km/h (19 mph)
for at least one minute.
1) Stop vehicle with engine run-
ning and touch ªSTARTº on
CONSULT-II screen.
2) Touch ªABSº.
3) Touch ªSELF-DIAG RESULTSº.
lThe screen shows the detected
malfunction and how many times
the ignition switch has been
turned since the malfunction.
MALFUNCTION REPAIR
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Make the necessary repairs following
the diagnostic procedures.
After repairing the malfunctions, erase
the self-diagnostic results stored in the
control unit by touching ªERASEº.
Check warning lamp for deactivation
after driving vehicle over 30 km/h (19
mph) for at least one minute.
