Fault warning - Check EV System

There have been a few posts about this warning arising intermittently, but never getting an OBD fault code from Spy or Torque. I have had it for 3 years, always in cold weather, never over the summer, and never when it was possible to get it to the dealer before it vanished - until today. I drove into the dealer with the lamp on, left the car in P but switched on, and asked them to check it. The technician came out with a dongle and a KIA branded tablet, plugged in, and got a fault code for 3-way valve in HVAC open (presumably when it should be shut?). I asked him to record it, so the rectification would be under warranty, and he replied that the tablet had already registered the data in "the system", which I understand to mean that it shows up in KIA UK's database.

So it seems that there are codes which Spy and Torque do not display or otherwise react to. As this was (as I suspected) an HVAC fault, I used the factory built-in test detailed in the Kia FSM to display a fault code, and it showed 108 (not the same numbering system as from the OBD port) which is given in the FSM just as "cooling valve open" so not as helpful as the dealer's KIA equipment.

The HVAC system has not detectably malfunctioned, so I think it is probably a defective sensor in the valve.

Anyway, it is booked in for service and repair in early January. Hopefiully, they will change the valve, and I won't see the fault again.

Am glad you find an answer for this glitch.

Have added a link to this on to the thread with HVAC error codes :- Heating and Cooling the Cabin - The HVAC System

Thanks. I see that Self Diagnosis Code 108 is shown as DTC Code B185A. I can't find the DTC Code list in the Service Manual - can you point me to the right direction please?

The best source of DTC error data for our car is KiaTechInfo.
Kia Global Information System (KGIS)
They show all the codes like so -
