Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Vehicle Stability Control System: Calibration
- DESCRIPTION
- After replacing the VSC relevant components or performing "Front wheel alignment adjustment", clearing and reading the sensor calibration data is necessary.
- Follow the chart to perform calibration.CALIBRATION PERFORM REFERENCE CHART
Replacing Parts Necessary Operation Skid Control ECU Yaw rate sensor and deceleration sensor zero point calibration Yaw Rate Sensor - Clearing zero point calibration data
- Yaw rate sensor and deceleration sensor zero point calibration
Front Wheel Alignment - Clearing zero point calibration data
- Yaw rate sensor and deceleration sensor zero point calibration
- CLEAR ZERO POINT CALIBRATION (When not using intelligent tester)
HINT:
After replacing the yaw rate sensor and deceleration sensor, make sure to clear zero point calibration data in the skid control ECU and perform zero point calibration.
- Clear the zero point calibration using the SST check wire.
SST 09846-18040
- Turn the ignition switch ON.
- Using SST, connect and disconnect terminals 12 (TS) and 4 (CG) of the DLC3 4 times or more within 8 seconds.
- Check that the warning light indicates the normal code.
- Remove SST.
- Clear the zero point calibration using the SST check wire.
- PERFORM ZERO POINT CALIBRATION OF YAW RATE SENSOR AND DECELERATION SENSOR (When not using intelligent tester)
HINT:
After replacing the brake master cylinder, make sure to perform yaw rate sensor and deceleration sensor zero point calibration.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
