CALIBRATION
NOTE: Use this procedure to center the steering wheel if:
-
The steering actuator (power steering gear assembly) has been replaced.
-
The steering control ECU has been replaced.
-
The steering column or steering intermediate shaft has been disconnected.
-
The steering wheel is still off-center after completing the steering angle sensor initialization.
1. VGRS SYSTEM CALIBRATION PROCEDURE (USING SST CHECK WIRE)
1. FACE TIRES STRAIGHT AHEAD
NOTE: Drive the vehicle to confirm that the steering wheel is centered.
NEXT -- Continue to next step.
2. CHECK DTC
(a) Check for DTCs See: Steering and Suspension/Steering/Testing and Inspection/Reading and Clearing Diagnostic Trouble Codes/Variable
Gear Ratio Steering System.

B -- Go to step 4
A -- Continue to next step.
3. PERFORM ACTUATOR ANGLE INITIALIZATION
NOTE: If the procedures from *1 to *2 are not completed within 1 minute, or if errors are made during these procedures, perform the
initialization again from the beginning.
(a) Turn the power switch ON (READY).
(b) Center the steering wheel.
(c) Using SST, connect terminals 12 (TS) and 4 (CG), and 13 (TC) and 4 (CG) of the DLC3. (*1)
SST: 09843-18040
(d) Disconnect SST from terminal 12 (TS) of the DLC3, and turn the steering wheel to the left 180° or more.
(e) Connect SST to terminal 12 (TS) of the DLC3.
(f) Disconnect SST from terminal 13 (TC) of the DLC3, and turn the steering wheel to the right 180° or more.
(g) Connect SST to terminal 13 (TC) of the DLC3. (*2)
HINT: When the master warning light comes on, DTC C1591/51 is memorized.
(h) Disconnect SST from the DLC3.
(i) Turn the power switch OFF.
NEXT -- Continue to next step.
4. FACE TIRES STRAIGHT AHEAD
(a) Confirm that the steering wheel is centered when facing the tires straight ahead.
NOTE: Drive the vehicle to confirm that the steering wheel is centered.
