2. HANDLING PRECAUTIONS FOR STEERING SYSTEM
(a) Care must be taken when replacing parts. Incorrect replacement may affect the performance of the steering system and result in a driving hazard.
3. HANDLING PRECAUTIONS FOR SRS AIRBAG SYSTEM
(a) The vehicle is equipped with a Supplemental Restraint System (SRS). Failure
to carry out service operations in the correct sequence could cause the SRS to unexpectedly
deploy during servicing. This may cause a serious accident. Before servicing (including
inspection, replacement, removal, and installation of parts), be sure to read the
precautionary notices for the Supplemental Restraint System (See page
).
4. PRECAUTIONS FOR REMOVAL, INSTALLATION AND REPLACEMENT OF ELECTRONIC POWER STEERING COMPONENTS
(a) After replacing the steering column assembly, clear the rotation angle sensor
calibration value, initialize the rotation angle sensor, and calibrate the torque
sensor zero point (See page ).
(b) If the above operations are not carried out correctly, the steering center
point (zero point) will deviate, causing a difference in steering effort between
right and left turns. If there is a difference in the steering effort between right
and left turns, perform the torque sensor zero point calibration (See page
).
5. HANDLING PRECAUTIONS FOR STEERING COLUMN
(a) When handling the electronic parts:
(b) When handling the steering column assembly:
(c) Before disconnecting the connectors related to the electronic power steering system, turn the ignition switch to on, center the steering wheel and then turn the ignition switch off.
(d) Before connecting the connectors related to the electronic power steering system, turn the ignition switch to off, center the steering wheel and then turn the ignition switch to ON.
NOTICE:
Do not turn the ignition switch to ON without the steering wheel centered.
