Monitor GDS Data
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.
- Turn the ignition switch ON.
- Connect a GDS and check the "Key state" on "Current Data".
- Is the Current Data normal?
YES
- Fault can be intermittent, caused by poor contact of connectors between the ICU and Antenna Coil wire harness. Or, the ICU memory was not cleared after repair. Thoroughly check connectors for looseness, poor contact, bending, corrosion, contamination, deterioration, or damage. Repair or replace relevant component as necessary and then go to "VERIFICATION OF VEHICLE REPAIR ".
NO
- Check for an open or short in the Antenna coil circuit and repair the circuit.
IF there is nothing wrong with the wire harness, replace the Antennae coil with an usable test sample and check for proper operation. If the problem is corrected, go to "VERIFICATION OF VEHICLE REPAIR ".
