Well, now that winter is here, I'm working on resolving some of the "issues" my 2009 F430 Spider has. The latest project is the a TPMS warning light that I can't get rid of. I have an Autel TPMS tool and have tried reprogramming the ECU but the writes fail and of course, all the dash tells me is "service TPMS" but no real detail as to what is wrong. I have replaced fuses and all the sensors show good battery with my scanner so I don't think the installed sensors are the issue. Question 1. Any suggestions on how to diagnose what the actual problem is? Question 2. The TPMS ECU is model 244952. Does anyone know of a place that tests these ECUs to see if the module is bad before replacing? I sure don't want to spend $2K if I don't have to. Question 3. Does anyone know how to disable the TPMS system entirely? In reading through the forums, the F430 TPMS sounds like it's more hassle than benefit so an option for me is just to disable the TPMS entirely to get the dash warning to go off. I know how to use a tire gauge... Thanks in advance!
