The HSM is detecting a short or open circuit condition I bet....mine is doing this, and AlfaOBD shows open circuit errors on both my seats.
I measured by resistance on each pad.
What resistance are you guys measuring? The Chilton manual shows 5-7 Ohms per seat element. However I read 7 ohms on both backrest pads, and 22 ohms on both bottom cushion pads. Seems odd both bottom pads would read the same ohms if failed? I assume they fail open or shorted.....
Now I am not sure if I have a bad HSM or both seat bottom elements are toast (no pun intended) haha.
