Adjustment of Neutral Position of Steering Wheel Angle SensorEFS0019R
●After removing/installing or replacing the ESP/TCS/ABS control unit, steering wheel angle sensor, steer-
ing components, suspension components, and tires, or after adjusting the wheel alignment, make sure to
adjust the neutral position of the steering wheel angle sensor before running the vehicle.
CAUTION:
To adjust the neutral position of the steering wheel angle sensor, make sure to use CONSULT-II.
(Adjustment cannot be done other than CONSULT-II.)
1. Stop the vehicle with the front wheels in the straight-ahead position.
2. Connect CONSULT-II to data link connector on the vehicle, and
turn the ignition switch to ON position (engine not running).
3. Touch “START”, “ABS”, “WORK SUPPORT” and “ST ANGLE
SENSOR ADJUSTMENT” on the CONSULT-II screen in this
order.

TROUBLE DIAGNOSIS
ABS Warning Lamp
Touch “ON” and “OFF”on the “ABS WARNING LAMP” screen to check that the ABS warning lamp operates as
follows.
NOTE:
During the active test when “OFF” on the “ABS WARNING LAMP” screen is touched, all of the ESP OFF indi-
cator lamp, SLIP indicator lamp, and ABS warning lamp flash once. This is not abnormal.
For Correct and Quick DiagnosisEFS001A8
PRECAUTIONS FOR TROUBLE DIAGNOSIS
●Before performing the trouble diagnosis, always read the GI-3, "PRECAUTIONS" to confirm the general
precautions.
●After replacement of ESP/TCS/ABS control unit, steering wheel angle sensor, steering parts, suspension
parts, or tires, and adjustment of alignment, always adjust the neutral position of steering wheel angle
sensor before driving.
●When the ESP/TCS/ABS control unit is replaced, check that the label on the computer unit is identical
color.
●After completing the trouble diagnosis, always erase the malfunctioning memory. Refer to BRC-81, "Pro-
cedure" .
●When inspection of the continuity or voltage between units is performed, check the connector terminals for
disconnection, looseness, bend, or collapse. If any malfunction is detected, repair or replace the applica-
ble part.
●Intermittent problems may be caused by a malfunction on harness, connector, or terminal. Move the har-
nesses, harness connectors, or terminals by hand to make sure that there is no contact malfunction.
●If a circuit tester is used for the check, be careful not to forcibly extend any connector terminal.
●For self-diagnosis, active test, and work support of ESP/TCS/ABS control unit with CONSULT-II, stop and
connect CONSULT-II and select “ABS”.
●CONSULT-II self-diagnosis results are displayed without regard to occurrence timing. In some case, the
later ones (timing value is small) appear on the next screen.
●While the self-diagnosis results of CONSULT-II shows a malfunction, if CONSULT-II active test is per-
formed, an engine system malfunction may be indicated. In this case, start the engine to resume the nor-
mal screen.
●ESP/TCS/ABS system electronically controls the brake operation and engine output. The following symp-
toms may be caused by the normal operations.
Operation ON OFF
ABS WARNING LAMP ON (Lamp ON) OFF (Lamp OFF)
Symptom Symptom description Result
Motor operation noiseDuring ESP, TCS, or ABS operation, sometimes a faint noise can be
heard. This is a motor operation noise in the ESP actuator.
Normal
Just after the engine starts, the motor operating noise may be heard.
This is a normal status of the system operation check.

Inspection procedure
1. SELF-DIAGNOSIS RESULT CHECK
Check the self-diagnosis results.
When any items other than “EMERGENCY BRAKE” is displayed in the self-diagnosis results, follow the
instructions below.
CAUTION:
“EMERGENCY BRAKE” is indicated when the control unit itself is detected internal error. If this dis-
play item was indicated, replace the control unit.
Is
“EMERGENCY BRAKE” is indicated in the self-diagnosis results?
>> Replace the ESP/TCS/ABS control unit, and perform the self-diagnosis again.

●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-29, "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, 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°
