VSC does not Operate or VSC does not Operate Correctly [12/2019 - 11/2023]: Procedure
- BRAKE PROBLEM CHECK
- Check whether the slip indicator light was illuminated when VSC did not operate.
OK
The slip indicator light was illuminated.
HINT:
When a DTC is stored, the slip indicator light is illuminated and VSC does not operate due to the fail-safe function.
- Check whether the vehicle speed was 15 km/h (9 mph) or less when VSC did not operate.
OK
The vehicle speed was 15 km/h (9 mph) or less.
HINT:
VSC does not operate when the vehicle speed is 15 km/h (9 mph) or less.
- Check whether the vehicle was driven straight for a few seconds at 35 km/h (22 mph) or more.
OK
The vehicle was not driven straight for a few seconds at 35 km/h (22 mph) or more.
HINT:
When the ignition switch is turned to ON, as steering angle sensor zero point calibration is not performed below 35 km/h (22 mph), VSC will not operate until the vehicle is driven straight for a few seconds at 35 km/h (22 mph) or more.
Result
Proceed to OK NG
Result:
OK
