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!
TPMs from Amazon work just fine. Have you tried the normal re-learn procedure? Key on ignition and hold the TPMs reset button on the lower area under the driver side dash. Should then go green on the dash for TPM Cal after a while of holding. Go drive around and should stay off after set. If you cycle through your TPMs is one tire not reading back? Have you tried deflating and reflating the tires?
Mine is an 09 so it doesn't have the TPMS reset button. I have also tried disconnecting the battery for a period of time to try and reset the system as well but that had no effect. I don't believe it's the sensors themselves, all of them show good battery readings from my Autel TPMS programmer. I *think* it's a ECU issue but I sure don't want to spend the money unless I have to. Any other ideas?
I didn’t know that a scanner could check battery levels in the TPMS. I have a X431, I’ll try it. What symbol is showing on your dash? Mine is just showing “Check Tire Pressures” for about 10 seconds, right after I start the car. Sent from my iPhone using FerrariChat.com mobile app
Ok yeah later system is a trip to the dealer to fix: https://www.ferrarichat.com/forum/posts/140981350/
I have an Autel TS508 tool for TPMS. I am very popular in the neighbourhood when everyone swaps to winter tires... The dash has a TPMS error warning light and in the DIC, it also shows the TPMS warning non stop. If you disconnect the battery and reconnect, it will give you a "service TPMS" and a picture of the car with 2 triangles under the wheels of a side profile. That goes away but the TPMS warning stays there.
So, small update. No resolution BUT, I ordered one of the Autel AP200M OBD readers. When I plug it in, you get a ton of detail and now the TPMS reader says "battery voltage too low" on all 4 wheels as fault codes. The cheap solution is to buy some new sensors and have them installed in the spring. OR, if someone has any idea how to disable the TPMS AND get rid of the super annoying TPMS error, that would be my first course of action. Another new wrinkle is that I have the "challenge" rims and those were factory ordered. The manual says that the challenge rims are not compatible with TPMS but I'm almost certain that's a misprint. I know the guy that ordered the car and there is no way he would have let that one go without being addressed. There are other posts on the Autel AP200M and I am also impressed. Super detailed. Things like how far the car has travelled in each gear, clutch wear and all kinds of useless statistics for engine, suspension, etc. Do you really need to know how many times you shifted to neutral (4,820)? Or who made the oil pressure sensor (Kavlic) or who made the oil temperature sensor (Bosch)?
I thought I read on this forum that the triangles under the wheels are a shock problem. I don’t know, but I’m sure I read that. I had the picture of the triangles under my wheels, but it went away. Sent from my iPhone using FerrariChat.com mobile app
The Autel and other generic testers do not give an accurate indication of the TPMS battery. Replace the sensors and drive the car 20'. The TPMS light will reset. Simple and easy... As to the triangles, they will frequently occur when the vehicle is lifted...and will subside once she's back on the ground and the system has had a chance to do another self-test. No mysteries and no drama!
Your car is a 2009. Have the TPMS sensors ever been replaced? If not, your most recent low battery reading is likely correct. They only last around 10 years or less. Sent from my iPhone using FerrariChat
I had an 06 350z with individual TPMS sensors integrated with the valve stem (more modern cars tend to use ABS wheel speed sensors for monitoring pressure, though some still use the older style) and they were beyond frustrating when they went bad. All sorts of errors OTHER than TPMS issues. They lasted about 8 years and then needed replaced. I would tend to agree with Need4Spd in that your most likely issue is (if they're original) old/dead sensors.
I just bought a set of TPMS in July for my late model (October) 2007 F40. The sensors are different for earlier(before July) 2007s, so make sure you are ordering the correct ones for your model year. They were just $139 per set of four at www.tpms.com and they work perfect! No issues in swapping out the old ones for new at my local tire installer. The system reset instantly on start up and has worked perfectly ever since.
In 2018, I had new Michelin pilot sport 4s tires put on my 2008 f430. Since I had Tpms light on, replaced all four Tpms sensors with Oro Tek OBE-011A sensors. 4 sensors for approx $80.oo with a 12/17 manufacture date. Installed tires on car. Started car and the Tpms light was out within 15 secs and I could now read all four tire pressures.
When you say the TPMS light went out when the new sensors were installed, what light went out? On my 2009 the dash says “Check Tire Pressures” but no other light come on. That phrase goes away after a few seconds when the car is running. Sent from my iPhone using FerrariChat.com mobile app
So I figured out my problem. The tire pressures were actually 3 psi too low. My handheld gauge was reading incorrectly. Once I brought the pressure up to 32 psi on the car dashboard, the Check Tire Pressure notice went away. Imagine that Sent from my iPhone using FerrariChat.com mobile app
