STEERING COLUMN: STEERING SYSTEM: PRECAUTION; 2013 MY FR-S [03/2012 -]

1. 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.

2. HANDLING PRECAUTIONS FOR SRS AIRBAG SYSTEM

(a) This 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 Supplemental Restraint System Service Precautions.

3. HANDLING PRECAUTIONS FOR STEERING COLUMN (When handling the steering column assembly)

(a) Avoid any impact to the steering column assembly, especially to the torque sensor. Replace the steering column assembly with a new one if it is dropped or subjected to any severe impacts.

(b) Do not pull the wire harness when moving the steering column assembly.

(c) When the steering column assembly has been replaced, perform the rotation angle sensor initialization and torque sensor zero point calibration Programming and Relearning.

(d) When the steering column assembly has been replaced, perform the VSC sensor neutral memorization Programming and Relearning.

(e) Do not release the tilt lever when the steering column assembly is not installed on the vehicle.

4. HANDLING PRECAUTIONS FOR STEERING COLUMN (When disconnecting or reconnecting the connectors)

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

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

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

(c) 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. If there is a difference in steering effort between turning right and left, perform the rotation angle sensor initialization and torque sensor zero point calibration Programming and Relearning.

5. HANDLING PRECAUTION FOR SPIRAL CABLE

(a) Do not replace the spiral cable with the battery connected and turn the ignition switch to ON.

(b) Do not rotate the spiral cable without the steering wheel with the battery connected and turn the ignition switch to ON.

(c) Ensure that the steering wheel is installed and aligned straight when inspecting the steering sensor.

(d) Be sure that the spiral cable with sensor sub-assembly is in the center position during installation and when removing and installing the steering wheel Installation.

CAUTION:
If the steering wheel is turned without the spiral cable installed in the neutral position, the cable may break.
