Steering System
STEERING COLUMN: STEERING SYSTEM: PRECAUTION
NOTICE:
When disconnecting the cable, some systems need to be initialized after the cable is reconnected Repair Instruction - Initialization.
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) 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 Service Precautions.
3. HANDLING PRECAUTIONS FOR STEERING COLUMN
(a) When handling the steering column assembly:
(1) Avoid any impact to the steering column assembly, especially to the motor or the torque sensor. Replace the steering column assembly with a new one if it is dropped or subjected to any severe impacts.
(2) Do not pull the wire harness when moving the steering column assembly.
(3) After replacing the steering column assembly or power steering ECU assembly, calibrate torque sensor zero point Programming and Relearning.
(4) Do not release the tilt lever when the steering column assembly is not installed on the vehicle.
(b) When disconnecting or reconnecting the connectors:
(1) When disconnecting the connectors related to the electronic motor power steering system, turn the power switch on (IG), center the steering wheel, turn the power switch off, and then disconnect the connectors.
(2) When reconnecting the connectors related to the electronic motor power steering system, make sure that the power switch is turned off, center the steering wheel and then turn the power switch on (IG).
NOTICE:
Do not turn the power switch on (IG) without the steering wheel centered.
(3) 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 Programming and Relearning.
