Variant Coding

WARNING: This page is about a different car, the 2017 Kia Optima. However, it is still accessible from the selected car via links, so may be relevant.

The HECU is programmed with a variant code based on the vehicle powertrain configuration. This variant code is used to determine the appropriate ESP calculations. Variant code programming should be performed whenever an HECU is replaced.
