General Information: General Description

WARNING: This page is about a different car, the 2015 Hyundai Sonata. However, it is still accessible from the selected car via links, so may be relevant.

The AHB ECU (Electronic Control Unit) receives APS data from ECM through CAN bus line to determine that regenerative braking is possible condition.

For example if APS signal is detected, that means driver wants acceleration so at that time regenerative braking is not allowed.
