STEERING SYSTEM
PRECAUTION
1.
HANDLING PRECAUTIONS ON STEERING SYSTEM
(a)
Be careful to replace the parts properly because they could affect the performance of the steering sys-
tem and result in a driving hazard.
2.
HANDLING PRECAUTIONS ON SRS AIRBAG SYSTEM
(a)
The vehicle is equipped with SRS (Supplemental Restraint System) such as the driver airbag and front
passenger airbag. Failure to carry out service operation in the correct sequence could cause the SRS
to unexpectedly deploy during servicing, possibly leading to a serious accident. Before servicing (in-
cluding removal or installation of parts, inspection or replacement), be sure to read the precautionary
notices in the supplemental restraint system
3.
HANDLING PRECAUTIONS ON STEERING COLUMN
(a)
Do not give an impact to the steering column assy, especially the motor and the torque sensor. If a great
impact is given (dropping it to the floor, etc.), replace it with a new one.
(b)
When removing the steering column assy, do not pull the harness.
(c)
When having replaced the steering column assy and/or the ECU, calibrate the zero point of the steer-
ing torque sensor.
(d)
In the case of disconnecting a connector related to the power steering system, turn the ignition switch
ON, set the steering wheel in the straight–ahead position and turn the ignition switch OFF before dis-
connecting the connector.
(e)
In the case of connecting a connector related to the power steering system, make sure that the ignition
switch is OFF at first. After connecting the connector, set the steering wheel assy in the straight–ahead
position, and then turn the ignition switch ON.
NOTICE:
Never turn on the ignition switch when the steering wheel assy is set in order than the straight–ahead
position.
(f)
If the above operation is not done, the zero point of the steering torque sensor is shifted away from
the proper position, making difference in the steering effort between right and left. If this happens, per-
form the zero point calibration of the steering torque sensor
