Calibration
CALIBRATION1. VGRS SYSTEM CALIBRATION PROCEDURE (USING SST CHECK WIRE)
NOTE: Use this procedure to center the steering wheel position if:
- VGRS actuator has been replaced
- VGRS ECU has been replaced
- Steering column or gear has been disconnected
- Steering wheel is still off-center after completing the steering angle sensor initialization in step 6.
Step 1 - 3:
Step 3 (continued) - 5:
Step 6 - 8:
Step 8 (continued):
Actuator angle initialization
2. VGRS SYSTEM CALIBRATION PROCEDURE (USING HAND-HELD TESTER)
a. Stop the vehicle and face the tires straight ahead.
b. Connect the hand-held tester to DLC3.
c. Turn the ignition switch ON.
d. Perform the steering angle adjust procedure from the VGRS menu.
e. Follow the tester prompts to complete procedure.
f. Confirm that the VGRS warning light OFF.
g. Turn the ignition switch OFF.
h. Disconnect the hand-held tester.
i. Confirm normal VGRS light operation.
j. Start the engine.
k. Turn the steering wheel from lock to lock to check that it rotates approximately 2.4 turns.
l. Actuator angle sensor learning confirmation procedure:
1. Start the engine.
2. Turn the steering wheel from center to the left 90° and then back to center.
3. Turn the steering wheel from center to the right 90° and then back to center.
4. Confirm that the steering wheel is centered.
5. Hold the steering wheel in the centered position for 3 seconds.
6. Perform the following check procedure;
- Turn the steering wheel slowly to the left.
- While turning the steering wheel to the left, turn off the engine.
- Continue to turn the steering wheel slowly to the left for 3 seconds.
7. Repeat steps 1.to 6.15 times.
NOTE: DTC C1568/68 requires that the fault occurs 5 consecutive times to set. The confirmation procedure must be performed multiple times to ensure the condition does not repeat.
8. Recheck for DTCs
- If C1568/68 is set, repeat the procedure for a second time. If C1568/68 is set again, replace the VGRS actuator.
m. Drive vehicle to confirm steering wheel is centered.
