PROCEDURE

1. PRECAUTION

NOTICE:

After turning the ignition switch off, waiting time may be required before disconnecting the cable from the negative (-) battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) battery terminal notice before proceeding with work.

(a) When handling the rack and pinion power steering gear assembly:

(1) Do not subject the rack and pinion power steering gear assembly (especially the motor and torque sensor) to any impact. Replace the rack and pinion power steering gear assembly with a new one if subjected to a strong impact.

(2) Do not pull the wire harness when moving the rack and pinion power steering gear assembly.

(3) When the rack and pinion power steering gear assembly has been replaced, perform torque sensor zero point calibration.

for Type B: Click here

(b) When disconnecting or reconnecting the connectors:

(1) Before disconnecting connectors related to the power steering system, turn the ignition switch ON, center the steering wheel, turn the ignition switch off, and then disconnect the connectors.

(2) Before reconnecting connectors related to the power steering system, ensure that the ignition switch is off. Then center the steering wheel and turn the ignition switch ON.

NOTICE:

Do not turn the ignition switch ON when the steering wheel is not centered.

(3) If the above operations are not carried out properly, the steering center point (zero point) will deviate, which may lead to a difference in steering effort between turning right and left.

HINT:

If there is a difference in steering effort between turning right and left, perform torque sensor zero point calibration.

2. ALIGN FRONT WHEELS FACING STRAIGHT AHEAD

3. SECURE STEERING WHEEL

(a) Secure the steering wheel with the seat belt in order to prevent rotation.

HINT:

This operation is useful to prevent damage to the spiral cable.
