VSC does not Operate or VSC does not Operate Correctly [06/2017 - 10/2020]: Procedure

1. 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.

2. 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.

3. Check whether the vehicle was driven straight for a few seconds at 15 km/h (9 mph) or more.

   OK

   The vehicle was not driven straight for a few seconds at 15 km/h (9 mph) or more.

   HINT: 

   When the engine switch is turned on (IG), as steering angle sensor zero point calibration is not performed below 15 km/h (9 mph), VSC will not operate until the vehicle is driven straight for a few seconds at 15 km/h (9 mph) or more.

See step  4

1. Turn the engine switch off.
2. Check that the yaw rate and acceleration sensor (airbag sensor assembly) has been installed properly.

   Refer to INSTALLATION [06/2017 - 09/2019] , or refer to INSTALLATION [09/2019 - 03/2020] , or refer to INSTALLATION [03/2020 - ]

   OK

   The yaw rate and acceleration sensor (airbag sensor assembly) is tightened to the specified torque.

   The yaw rate and acceleration sensor (airbag sensor assembly) is not installed in a tilted position.

   Proceed to
   OK
   NG

Result: 

OK 

OBTAIN YAW RATE AND ACCELERATION SENSOR ZERO POINT. Refer to  CALIBRATION [06/2017 - 10/2020] 

Result:
