VARIABLE GEAR RATIO STEERING SYSTEM - VGRS System Suspends right after Engine Start


INSPECTION PROCEDURE

NOTICE:
When replacing the steering actuator assembly, perform actuator angle neutral point calibration and initialization after replacement (Click here).
1.CHECK FOR DTC

2.CUSTOMER PROBLEM ANALYSIS

  1. Confirm the conditions present when the VGRS temporarily stopped.

    		Proceed to
    The system temporarily stopped during normal driving.
    		A
    The system temporarily stopped under harsh conditions such as when turning the steering wheel while the vehicle is stopped.
    		B

    HINT:
    When the steering torque is large, the actuator easily overheats. In this situation, the system is stopped to prevent the actuator from overheating.

3.CHECK STEERING EFFORT

  1. Check the steering torque when the steering wheel is turned with the vehicle stopped (for 1VD-FTV: Click here, for 1UR-FE: Click here, for 3UR-FE: Click here).

    OK:
    The steering torque is normal.
    HINT:
    When the power steering system has failed, the system is stopped to protect the system when the load torque is large.

4.CUSTOMER PROBLEM ANALYSIS

  1. Check if the system stops repeatedly when steering the vehicle.

    OK:
    The system does not stop repeatedly.
    HINT:
    After the engine switch is turned on (IG) and the steering wheel is operated, an initial check of the lock is performed. When operating the steering wheel during the initial check, VGRS operation may be stopped, but operation is resumed again quickly.

REPLACE STEERING ACTUATOR ASSEMBLY (Click here)
OK
