Calibration Research Tips: Hyundai Variant Coding

I-CAR · September 9, 2020 · Hyundai

Summary

This article explains Hyundai's variant coding procedure, which is required when replacing ADAS components like forward-facing cameras and radar sensors. Variant coding uses a scan tool to introduce a new module to the vehicle, ensuring proper communication and preventing diagnostic trouble codes (DTCs).

What to do on the job

Perform the variant coding procedure using a scan tool whenever replacing a Hyundai ADAS sensor/module or when a variant coding DTC is present.

How to use it

Use this document to justify the necessity of scan tool variant coding and programming time on estimates and supplements when replacing Hyundai ADAS components, such as Smart Cruise Control (SCC) or Forward Collision Avoidance (FCA) radar sensors.
