Calibration Procedure

NOTE:
Ensure that the steering wheel is level (on center) prior to calibration of the steering angle sensor.





1. Using the SST, connect terminals Ts and E1 of DLC1.

2. Turn the ignition switch "ON".

3. Verify that the shift lever is in the Park ("P") range.

4. Press the "TRAC OFF" switch and hold it.*

5. Depress the brake pedal 3 or more times within 2 seconds.

6. Check that the VSC buzzer sounds for 3 seconds.

A. If the VSC buzzer sounds, go to step 7.

B. If the VSC buzzer does not sound, go to step 2 and repeat the procedure.

NOTE:
If the VSC buzzer STILL will not sound, there is a malfunction in the steering angle sensor. Check for DTCs.

7. The sensor calibration is normal and complete.
