SymptomRemedy Probable causes
Noisy or disturbed waveformOpen circuit in sensorReplace sensor
Open circuit in harnessCorrect harness
Incorrectly mounted wheel speed sensorMount correctly
ABS rotor with missing or damaged teethReplace ABS rotor
Caution
Because the wheel speed sensor cables move together with the front and rear suspension, they
vibrate greatly when driving over poor road surfaces. As a result, the sensor harnesses should also
be shaken when monitoring of output waveforms of the wheel speed sensors in order to simulate
conditions such as driving over poor road surfaces.
HYDRAULIC UNIT CHECK
1. Jack up the vehicle and support the vehicle with rigid racks placed at the specified jack-up points
or place the wheels which are checked on the rollers of the braking force tester.
Caution
(1) The roller of the braking force tester and the tyre should be dry during testing.
(2) When testing the front brakes, apply the parking brake, and when testing the rear brakes,
stop the front wheels by chocking them.
2. Turn the ignition key to the “LOCK” (OFF) position and set the MUT-II.
Caution
Turn the ignition key to the “LOCK” (OFF) position before connecting or disconnecting the
MUT-II.
3. After checking that the shift lever is in neutral, start the engine.
4. Use the MUT-IIto force-drive the actuator.
NOTE
(1) During the actuator test, the ABS warning lamp will illuminate and the anti-skid control will be
cancelled.
(2) When the ABS has been interrupted by the fail-safe function, the MUT-IIactuator testing cannot
be carried out.
5. Turn the wheel by hand and check the change in braking force when the brake pedal is depressed.
When using the braking force tester, depress the brake pedal until the braking force is at the following
values, and check that the braking force decreases when the actuator is force-driven.

REMEDY FOR A FLAT BATTERY
When booster cables are used to start the engine when the
battery is completely flat and then the vehicle is immediately
driven without waiting for the battery to recharge itself to
some extent, the engine may misfire, and driving might not
be possible. This happens because ABS consumes a great
amount of current for its self-check function. If this happens,
recharge the battery fully.
Caution
The vehicle posture will be unstable during braking, so
do not drive the vehicle with the ABS-ECU connector
disconnected or with the ABS not operating for any other
reason.

STEERING -On-vehicle Service37A-9
POWER STEERING FLUID LEVEL CHECK
1. Park the vehicle on a flat, level surface, start the engine,
and then turn the steering wheel several times to raise
the temperature of the fluid to approximately 50 - 60_C.
2. With the engine running, turn the wheel all the way to
the left and right several times.
3. Check the fluid in the oil reservoir for foaming or milkiness.
Check the difference of the fluid level when the engine
is stopped, and while it is running. If the change of the
fluid level is 5 mm or more, air bleeding should be done.
POWER STEERING FLUID REPLACEMENT
1. Raise the front wheels on a jack, and then support them
with rigid racks.
2. Disconnect the return hose connection.
3. Connect a vinyl hose to the return hose, and drain the
oil into a container.
4. Disconnect the ignition coil connectors. (Refer to
GROUP16 - Ignition System.)
5. While operating the starting motor intermittently, turn the
steering wheel all the way to the left and right several
times to drain all of the fluid.
6. Connect the return hoses securely, and then secure it
with the clip.
7. Fill the oil reservoir with specified fluid up to the lower
position of the filter, and then bleed air.
Specified fluid:
Automatic transmission fluid DEXRONII
Caution
Do not use ATF-SPIIM and ATF-SPIII.
POWER STEERING SYSTEM BLEEDING
1. Jack up the vehicle and support the front wheels with
rigid racks.
2. Disconnect the ignition coil connectors. (Refer to
GROUP16 - Ignition System.)
3. Cranking the engine with the starter several times
intermittently (during 15 to 20 seconds), turn the steering
wheel left and right fully five or six times.
Caution
(1) During the bleeding, refill the fluid so that the
level never falls below the lower position of the
filter.
(2) Be sure to bleed air only while cranking. If the
bleeding is done with the engine running, the air
will be broken up and absorbed into the fluid.
4. Connect the ignition coil connectors and idle the engine.
5. Turn the steering wheel left and right fully until no bubbles
comes out in the oil reservoir.
6. See that the fluid is not milky and that the fluid level
is up to the specified position on the level gauge.
7. See that the fluid level changes little when the steering
wheel is turned left and right.
8. Check difference in fluid levels between the engine
stopped and running.
Fluid level change: Within 5 mm

ADJUSTMENTS AND REPLACEMENT DURING
POWER WINDOW MALFUNCTION
If the window glass does not rise but automatically descends,
adjust and replace the window glass as follows:
1. Remove the door trim and waterproof film. (P.42-27)
2. Remove the window regulator assembly from the door
window glass, and raise and lower the window glass with
your hand and check the operating force.
Remarks Insert a cushion, etc. to prevent damage of
the glass if it accidentally drops.
3. If the door window glass does not rise and descend
smoothly, perform the following check and repair.
DCheck the installation condition of the runchannel.
DStraighten twist in the door sash.
DCheck the installation condition of the lower sash
or the center sash.
NOTE
The lower sash cannot normally be adjusted, but it may
be possible to adjust the sash span slightly within the
range allowed by manufacturing tolerances by pushing
the lower sash outwards while re-installing it.
4. If repair or adjustment is not possible, replace the door
assembly.
POWER WINDOW SAFETY MECHANISM
CHECK
1. Set a wood piece of about 10 mm thick as shown in
the figure, and raise the window glass.
2. Check that the window glass descends by about 150
mm when it catches the wood piece. If it does not, perform
troubleshooting. (Refer to GROUP 54B.)
POWER WINDOW TIMER FUNCTION CHECK
9Close the door and turn the ignition switch in the OFF position,
and then check the power window operates for 30 seconds.
If it does not, perform troubleshooting.(Refer to GROUP 54B.)

TROUBLESHOOTING
The windshield wiper-washer is controlled by the smart wiring system (SWS). Refer to Group 54B for
troubleshooting.
NOTE
If ETACS-ECU is faulty, the windshield wiper can be operable in LO mode only as the fail - safe function.
(Normally the windshield wiper is operable when the ignition switch is turned to the ACC position. When
the fail - safe function is enabled, it is operable only when the ignition switch is turned to the ON position.)
ON-VEHICLE SERVICE

INSPECTIONS
(1) Check the change in the intermittent time of the wiper
operation by using the windshield intermittent wiper
volume.
(2) Carry out troubleshooting if any of them is faulty.

6. Inspection of the SRS-ECU harness connector should be carried out by the following procedure.
Insert the special tool (probe, MB991222, in the harness set) into the connector from harness side
(rear side), and connect the tester to this probe. If any tool than specified is used, damage to the
harness and other components will result. Furthermore, measurement should not be carried out by
touching the probe directly against the terminals from the front of the connector. The terminals are
plated to increase their conductivity, so that if they are touched directly by the probe, the plating
may break, which will cause drops in reliability.

7. SRS components and seat belt with pre-tensioner should not be subjected to hart, so remove the
SRS-ECU, driver’s and front passenger’s air bag modules, clock spring, and seat belt with pre-tensioner
before drying or baking the vehicle after painting.

8. Whenever you finish servicing the SRS, check warning lamp operation to make sure that the system
functions properly. (Refer to P.52B-6.)
9. Make certain that the ignition switch is LOCK (OFF) position when the MUT-IIis connected or
disconnected.
10. If you have any questions about the SRS, please contact your local distributor.
