Innova SDS50 SDS-Tech: Suspension Calibration

Purpose

To explain how to relearn the Suspension Calibration while using the Innova SDS50 SDS-Tech Tablet Scan Tool.

Introduction

The Suspension Calibration function on a vehicle is a critical aspect of its overall performance and handling characteristics. It refers to the process of fine-tuning and adjusting the suspension system to optimize its behavior, responsiveness, and comfort according to specific requirements or driving conditions.

The suspension system of a vehicle is responsible for managing the interaction between the tires and the road surface. It plays a crucial role in maintaining stability, controlling body movement, absorbing shocks, and providing a comfortable ride. Suspension calibration involves adjusting various components and settings of the suspension system to achieve the desired balance between comfort and performance.

By optimizing the suspension calibration, vehicles can deliver enhanced driving dynamics, improved traction, reduced body roll, and better stability under various driving conditions, ultimately providing a safer and more enjoyable driving experience.

Procedure

Step 1 - Connect Innova SDS50 SDS-Tech Tablet Scan Tool to the vehicle and select 'Workshop Tools' function

First, connect the Innova SDS50 SDS-Tech Tablet Scan Tool to your vehicle via the On-Board Diagnostics (OBD) connector to retrieve the vehicle's information, such as Vehicle Identification Number (VIN) and model.

Then, select the 'Workshop Tools' section.

Step 2 – Select the ‘Suspension Calibration’ function

The Innova SDS50 SDS-Tech Tablet Scan Tool shows the list of functions available for your vehicle. To initiate the Transmission Reset, choose the 'Suspension Calibration’ item from the list.

After that select ‘[34] Level Control System Control Module’ item to enter the system responsible for the ‘Suspension Calibration’ function on the vehicle.

NOTE: The system name and function procedure differ depending on the make and model of the vehicle.

Step 3 – Choose the function to perform

Select the ‘Leveling calibration for ride control system’ item.

NOTE: The functions differ depending on the make and model of the vehicle.

Step 4 – Perform the 'Suspension Calibration’ function

	After select the ‘Leveling calibration for ride control system’ function, the Scan Tool shows some notes for the process. Tap 'Next’ button to go to the next step.
	After that the Scan Tool shows some requirements that must be met first before performing the 'Suspension Calibration’ function. If not, the resetting process maybe failed. After that the Scan Tool shows some requirements that must be met first before performing the 'Suspension Calibration’ function. If not, the resetting process maybe failed.
	Wait for the Scan Tool retrieves the data on the Electronic Control Module (ECU) and show on the screen as in the image. Then tap the ‘Next’ button to go to the next step.
	Select the desired option to perform the calibration. In this case, tap the ‘Left front’ option to perform.
	Once you have selected the 'Next' button in the previous step, the Suspension Calibration function will prompt you to input the new calibrated value for it to perform the function.
	Once you have entered the new calibrated value, select the 'Next' button to proceed to the next step.
	Wait for the ECU to check the value and tap the ‘Next’ button to write the new calibrated value to the ECU memory.
	Wait and check the result of performing the function. Tap the 'Yes’ button to finish the ‘Suspension Calibration’ function for the ‘Left Front’ option. Tap the other option to perform ‘Suspension Calibration’ for the other side.
