I'm getting a TPMS electrical error and the message is Check TPMS Module. The yellow low tire pressure light is on and the red triangle is flashing. I've searched the posts and I've seen where the module can be located, but can it be isolated to the module itself? Or can it be more the sensors / batteries? What's the best way to approach this before heading into the dealership? I've taken the battery off for 10 min but that didnt make a difference. TIA for any suggestions.
