Adjustment of Steering Angle Sensor Neutral PositionEFS0019R
In case of doing work that applies to the list below, make sure to adjust neutral position of steering angle sen-
sor before running vehicle.
×: Required
–: Not required
CAUTION:
To adjust neutral position of steering angle sensor, make sure to use CONSULT-II.
(Adjustment cannot be done without CONSULT-II.)
1. Stop vehicle with front wheels in straight-ahead position.
2. Connect CONSULT-II and CONSULT-II CONVERTER to data link connector on vehicle, and turn ignition
switch ON (do not start engine).
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
3. Touch “ABS”, “WORK SUPPORT” and “ST ANGLE SENSOR ADJUSTMENT” on CONSULT-II screen in
this order. Refer to BRC-77, "
CONSULT-II BASIC OPERATION PROCEDURE" .
4. Touch “START”.
CAUTION:
Do not touch steering wheel while adjusting steering angle
sensor.
5. After approximately 10 seconds, touch “END”. (After approxi-
mately 60 seconds, it ends automatically.)
6. Turn ignition switch OFF, then turn it ON again.
CAUTION:
Be sure to carry out above operation.
7. Run vehicle with front wheels in straight-ahead position, then
stop.
8. Select “DATA MONITOR”, “SELECTION FROM MENU”, and “STR ANGLE SIG” on CONSULT-II screen.
Then make sure “STR ANGLE SIG” is within 0 ±3.5 deg. If value is more than specification, repeat steps 3
to 7.
9. Erase memory of ABS actuator and electric unit (control unit) and ECM.
10. Turn ignition switch OFF.

For Fast and Accurate DiagnosisEFS004H8
PRECAUTIONS FOR DIAGNOSIS

Before performing diagnosis, always read precautions. Refer to BRC-58, "How to Proceed With Diagno-
sis" .

If ESP/TCS/ABS control unit steering angle sensor, steering system parts or suspension system parts
have been replaced, or if alignment has been adjusted, be sure to adjust neutral position of steering angle
sensor before driving. Refer to BRC-51, "
Adjustment of Steering Angle Sensor Neutral Position" .

After diagnosis is finished, be sure to erase memory. Refer to BRC-79, "SELF-DIAGNOSIS" .

When checking continuity and voltage between units, be sure to check for disconnection, looseness,
bend, or collapse of connector terminals. If any malfunction is found, repair or replace connector termi-
nals.

For intermittent symptoms, possible cause is malfunction in harness, harness connector, or terminals.
Move harness, harness connector, and terminals to check for poor connections.

If a circuit tester is used for the check, be careful not to forcibly extend any connector terminal.

To use CONSULT-II to perform self-diagnosis of ESP/TCS/ABS control unit active tests, or work support,
first stop work, then connect CONSULT-II and select “ABS”.

While self-diagnostic results of CONSULT-II shows malfunction, if CONSULT-II active test is performed,
an engine system error may be indicated. In this case, start engine to resume the normal screen.

ESP/TCS/ABS system electronically controls brake operation and engine output. The following symptoms
may be caused by normal operations:
Symptom Symptom description Result
Motor operation noiseThis is noise of motor inside ESP/TCS/ABS control unit. Slight noise
may occur during ESP, TCS, and ABS operation.
Normal
When the vehicle speed goes over 20 km/h (12.5 MPH), motor and
valves operating noise may be heard. It happens only once after IGN
(ignition) is ON. This is a normal status of the system operation check.
System operation check
noiseWhen engine starts, slight “click” noise may be heard from engine room.
This is normal and is part of system operation check.Normal
ESP/TCS operation
(SLIP indicator lamp blink-
ing)TCS may activate momentarily if wheel speed changes when driving
over location where friction coefficient varies, when up/downshifting, or
when fully depressing accelerator pedal.
Normal
Cancel the ESP/TCS
function for the
inspection on a chas-
sis dynamometer. For inspection of speedometer or other instruments, press ESP OFF
SW to turn ESP/TCS function off.
When accelerator pedal is depressed on a chassis dynamometer (fixed
front-wheel type), vehicle speed will not increase. This is not normal. It is
result of TCS being activated by stationary front wheels. Warning lamp
may also illuminate to indicate “sensor system error”. This is also nor-
mal, and is the result of the stationary front wheels being detected. To be
certain, restart engine, and drive vehicle at 30 km/h (19 MPH) or more.
Make sure warning lamp does not illuminate.
ABS operation (Longer stop-
ping distance)On roads with low friction coefficients, such as snowy roads or gravel
roads, vehicles with ABS may require a longer stopping distance. There-
fore, when driving on such roads, avoid overconfidence and keep speed
sufficiently low.Normal
Insufficient feeling of accel-
erationDepending on road conditions, driver may feel that feeling of accelera-
tion is insufficient. This is because traction control, which controls
engine and brakes to achieve optimal traction, has the highest priority
(for safety). As a result, there may be times when acceleration is slightly
less than usual for the same accelerator pedal operation.Normal

TROUBLE DIAGNOSIS

3. STEERING ANGLE SENSOR CIRCUIT CHECK
1. Disconnect ESP/TCS/ABS control unit connector and steering angle sensor connector.
2. Check for continuity between ESP/TCS/ABS control unit and
steering angle sensor (harness connector M81).
3. Check for the continuity between the steering angle sensor and
ground.
Is inspection result OK?
YES >> GO TO 4.
NO >> Repair or replace the disconnected harness.
4. DATA MONITOR CHECK
Perform the “STR ANGLE SIG” value in “DATA MONITOR” and check that it is in normal condition.
Is inspection result OK?
YES >> Perform the ESP/TCS/ABS control unit self-diagnosis again.
NO >> Replace the spiral cable (with the steering angle sensor) and adjust the neutral position of steer-
ing angle sensor. BRC-51, "
Adjustment of Steering Angle Sensor Neutral Position" .

STEERING WHEEL


Start engine. With engine at idle, turn steering wheel from stop
to stop and measure steering angles.

If angles are outside specification, measure rack stroke.

If rack stroke is outside of specification, disassemble steering
gear to check rack stroke.

Steering angles are not adjustable. If any of steering angles is different from specified value, check steer-
ing gear, the column and the front suspension components for wear or damage. If any abnormality exists,
replace the malfunctioning parts.
Removal and InstallationEGS0004F
REMOVAL
1. Remove air bag module. Refer to SRS-30, "DRIVER AIR BAG MODULE" .
2. Remove horn connector.
3. Remove steering wheel mounting nut and paint mating marks on steering wheel body and top of column
shaft.
4. Using a steering wheel puller (SST), remove steering wheel.
INSTALLATION
Paying attention to following items, install in the reverse order of removal.
NOTE:

When reconnecting spiral cable, fix cable with a tape so that fixing case and rotating part keep aligned.
This will omit neutral position alignment procedure during spiral cable installation.

Neutral position (refer to figure)... Gently turn spiral cable clock-
wise until it comes to the stop. Then turn it counter clockwise
(approximately 3.0 turns) until centering mark is aligned with
adjustment mark. (Service part is fixed in neutral position with
stopper. It can be installed onto steering wheel without align-
ment once stopper is removed.)
CAUTION:

Place steering wheel as follows: Front wheels in straight-
ahead position. R mark on the cancel claw faces down. 3
bosses align with 3 holes behind steering wheel assembly.
Check that spiral cable is placed in neutral position and that
locating pin on the left of the spiral cable is aligned with the
locating pinhole behind the steering wheel assembly.

Do not rotate spiral cable more than necessary. Do not tighten them excessively. (The cable may
be torn off.)

After installation, check system for proper operation by observing air bag warning lamp.

If air bag indicator indicates any abnormal condition, use self-diagnosis function or CONSULT to
reset or cancel memory.Inner wheel Minimum : 36°
