- Description An ignition coil is an induction coil in an engine's ignition system which transforms the battery's low voltage to the high voltage needed to create an electric spark in the spark plugs to ignite the fuel. Coils have an internal resistor while others rely on a resistor wire or an external resistor to limit the current flowing into the coil from the battery 12V supply. - Troubleshooting Connector assembly status test

1.Remove the connector (A) and reinstall it.

Hyundai Accent (HC) (2017 - 2022) Service Manual: Troubleshooting

- Troubleshooting Limp Home Mode Limp Home Mode features a fail-safe function that prevents dangerous situations in the event of a transmission failure. The vehicle will be driven in limp home mode if the transmission malfunctions. In this mode, the transmission operates at a minimal functionality level (fixed shifting, limited shifting, reverse, neutral), making it possible for the vehicle to reach a service center.
