System STATES In LEARNING MODE

WARNING: This page is about a different car, the 2021 Hyundai Kona. However, it is still accessible from the selected car via links, so may be relevant.

In learning mode, the BES System can be set in 6 different states, depending on the status of the terminals and Engine status:

System State Terminal Status Engine Status
  1. OFF - Locked
OFF Stopped
  1. OFF - Unlocked
OFF Stopped
  1. ACC
ACC Stopped
  1. IGN
IGN1, IGN2, ACC Stopped
  1. Start
IGN1, Start Cranking
  1. IGN - Engine
IGN1, IGN2, ACC Running
(means "self-running")

Referring to the terminals, the system states described in the table above are the same as those found in a system based on a mechanical ignition switch.

One of the features distinctive from the Mechanical Ignition Switch-based system is that the BES system allows specific transition from [OFF] to [START] without going through [ACC] and [IGN] states.
