PRECAUTIONS FOR DIAGNOSIS

Be sure to check the procedures of “How to Perform Trouble Diagnosis” in advance. Refer to GI-4, "Gen-
eral Precautions" .

Always adjust the neutral position of steering angle sensor before driving when removing and installing
ABS actuator and electric unit (control unit), steering angle sensor, suspension parts and adjusting align-
ment. Refer to BRC-40, "
Adjustment of Steering Angle Sensor Neutral Position" .

Always erase memory after completing trouble diagnosis. Refer to BRC-58, "ERASE MEMORY" .

When inspection of the continuity or voltage between modules or units is performed, check connector ter-
minals for disconnection, looseness, bend, or collapse. Repair or replace applicable part if any non-stan-
dard condition is detected.

Intermittent malfunctions may be caused by a poor connection in the harness, connectors, and terminals.
Move harnesses, harness connectors, and terminals by hand to make sure all connections are solid and
undamaged.

Do not to forcibly extend any connector terminal if a circuit tester is used for the check.

The symptom shown in the table may occur, but the system is operating normally.
Symptom Symptom description Result
Motor operation soundThis is the operation sound of the motor in the actuator and electric unit.Slight
sound may occur during VDC, TCS and ABS operation.
Normal
Just after the engine starts, the motor operating noise may be heard. This is a
normal status of the system operation check.
System operation check soundWhen engine starts, “click” sound may be heard from engine room. This is nor-
mal status of system operation check.Normal
VDC/TCS operation
(SLIP indicator lamp ON)TCS may activate momentarily if wheel speed changes when driving over
location where friction coefficient varies, when downshifting, or when fully
depressing accelerator pedal.
Normal
Cancel the VDC/
TCS function for
the inspection on
a chassis dyna-
mometer. Before the speed meter inspection, push VDC OFF switch to cancel the VDC/
TCS function.
When accelerator pedal is depressed on a chassis dynamometer (front wheel
fixing type), the vehicle speed will not increase. This is normal. It is result of
TCS being activated by stationary front wheels. The warning lamp may also
turn on to show “sensor system malfunction” in this case. This is also normal,
and is the result of the stationary front wheels being detected. Restart engine,
and drive the vehicle at 30 km/h (19 MPH) or more to make sure that the warn-
ing lamp no longer turns on.
ABS operation
(Longer stopping distance)When driving on roads with a low coefficient of friction, such as snowy roads or
gravel roads, the stopping distance is sometimes longer for vehicles equipped
with ABS. Therefore, when driving on such roads, drive at a sufficiently
reduced speed to be safe.Normal
Sluggish feelDepending on road conditions, the driver may have a sluggish feel. This is
because traction control, which controls engine and brakes to achieve optimal
traction, has the highest priority (for safety). As a result sometimes the driver
has a less slight sluggish feel in response than usual acceleration feel.Normal

Removal and InstallationBFS000EQ
COMPONENTS
REMOVAL
Be careful of the following.
CAUTION:
When removing the wheel sensor, do not rotate it if possible, and do not forcibly pull the wheel sensor
harness.
INSTALLATION
Note the following, and tighten bolts to the specified torque.

Check the inside of the wheel sensor mounting hole for foreign materials, the rotor surface for iron chips
and other foreign materials. Clean both the wheel sensor mounting hole and the rotor surface before
installation. Replace the wheel sensor if there is any non-standard condition.

Completely push in rubber clamp of strut bracket and body bracket until they lock when installing front
wheel sensor so that the wheel sensor harness will not be twisted. Install grommet groove onto bracket
with yellow line on the harness facing bracket opening (mounting hole). There should be no twists in the
harness when installed.

When installing the rear sensor, securely install the harness mount of the rear suspension member so that
the wheel sensor harness is not twisted. In addition, there should be no twists in the harness when
installed.
