A lot of scanners will only read eobd on these.
Try going in under Hyundai H100 van with 2.5d if you can, you may find more data/codes.
However, it sounds as though it's had a new ECU which hasn't been configured:
1)
In the case of the vehicle with 2.5litre A-Engine CRDi, it is normal if the glow lamp with ignition On is illuminated during preheating(max. 10 seconds) according to the ambient temperature and then put off. The glow lamp is illuminated at all times for the vehicle with ECU having not performed automatic recognition procedure.
2)
When the customer's complaint arises from glow lamp illumination at all time, if there is no DTC code(P1629) existing, test the ECU by performing ECU Automatic Recognition routine using HI-SCAN.
3)
When MT/AT is properly selected, press [ESC] key to stop the automatic recognition.
4)
If the ECU is at the initial state, start the automatic recognition routine to adapt the Transaxle type.
5)
After adaption, about 5 seconds after with ignition OFF, check whether the adaption is normal or not through glow lamp illumination with ignition ON.
6)
Whenever ECU is replaced with a new one or an used one from other transaxle type of vehicle, automatic recognition routine is necessary.
