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 T(S) and E(1) 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.

* The "TRAC OFF" switch is located where the low tire pressure warning reset switch is on non-VSC equipped Sienna vehicles. Sienna vehicles equipped with VSC are not equipped with the Low Tire Pressure Warning System.
