Vehicle Stability Control System: Calibration
- After replacing the VSC relevant components or performing "Front wheel alignment adjustment", clear and read the sensor calibration data.
- Follow the chart to perform calibration.PARTS OPERATION CHART
Replacing Parts / Operation Necessary Operation Skid control ECU Yaw rate and acceleration sensor zero point calibration Yaw rate and acceleration sensor - Clearing zero point calibration data
- Yaw rate and acceleration sensor zero point calibration
Front wheel alignment adjustment - Clearing zero point calibration data
- Yaw rate and acceleration sensor zero point calibration
- CLEAR ZERO POINT CALIBRATION DATA (for Using an Intelligent Tester)
- Turn the ignition switch off.
- Connect the intelligent tester to the DLC3.
- Turn the ignition switch to the ON position.
- Turn the intelligent tester on.
- Switch to skid control ECU to erase the codes using the intelligent tester. Enter the following menus: DIAGNOSIS / OBD/MOBD / ABS/VSC / RESET MEMORY.
- Turn the ignition switch off.NOTE: If the ignition switch is turned to the ON position for more than 15 seconds with the shift lever in the P position after zero point of the yaw rate and acceleration sensor has been cleared, only the zero point of the yaw rate sensor will be stored. If the vehicle is driven under these conditions, the skid control ECU will store the zero point calibration for the acceleration sensor as not being completed. The skid control ECU will then also indicate this as a malfunction of the VSC system using the warning lights.
