Tire Pressure Monitoring System

Taz,

Did you get these orange ones installed and did they work fine? I need to replace my sensors.

Thanks!

 

We-us&them&you&I- can together work on a desirable electronics package for our electronically deprived cars
Parts are all out there at reasonable prices. Display Heads aren't yet integrated but getting close
some centering around rear view mirrors. Many are wireless which is always a giant plus.

$1k buys a lot of electronics now days, but deciding the right equipment can be a timeconsuming.

*****************
OK, if anyone is already working a mini-project integrating several pieces, shout now re your status and thoughts.
*****************

My ideal starter package would contain:
1) Car Bluetooth for cell w/voice transmit command & steering wheel switch.
2) Car Bluetooth for gps w/voice navigation request & steering wheel switch.
3) Ear Bluetooth integrating with others.
4) Forward camera with 1 hour memory stick display in RearViewMirror
5) 2 Rear camera angled for side lane activity. display in RearViewMirror
6) Spead readout 2 .8"high led digits - unsure where
7) 2way radio - ham or GFRS - w/Bluetooth integration
*******
Cameras and Gps are already mature products, the ideal display would take research for size and mountability
I could live without #4 but find Fuel display of miles remaining or mpg would be interesting and not require much.

So, let's take this thread anywhere positive...recommendations, suggestions.
Brainstorming rules apply=absolutely no negative or disparaging remarks. Post pictures of products you like.
If you don't know how to do that...ask & learn.

We can come up with the 'FChat Future is Now' package. Maybe we could even
setup a conference meeting but Tech Toys fits but we'll snag more contributors
right in FChat Tech-not model specific. I'm excited with the possibilities.
If we standardized on primary design it makes any troubleshooting a group function,
hence much easier activity than everyone fighting their own tech battles.

Me bad. I thought I was opening a new thread, not hijacking an old one. Will repost.

 

Just read the whole thread on this, and must admit in rather a lot of dis-believe.

What an utter mess.

In order to have a system to inform you about your tyre pressures, the latter being maybe the most single important thing for your safety (together with brakes), the mutations in systems, and differences between euro- and US spec cars are just beyond words.
This is again a prime example on how to add some weight and 200 metres of wiring loom to a car, and by the looks of it certainly not enhancing its' functionality.

What good is a system if you can't depend on it, and have to replace batteries (at considerable cost) every so-many years? Just buy a decent gauge and be done with it.

 

+1 -- a classic example of "green" that just isn't (because the complexity and costs far, far outweigh the best possible minor benefit of maybe not reducing your mpg by a few % if you drive with a slightly under-inflated tire -- if it all works perfectly -- and it doesn't!).

 

It's not a green issue, but a safety issue. The NHTSA and the US Federal government have made it a law that all new cars must have tire pressure monitoring systems installed.

I originally posted a new TPMS thread a few months ago in the 360/430 forum, but figured it was better to continue in this thread as it's more complete--

Backstory:

I bought a 05 F430 a few months ago in LA, and drove it back home to nor cal the same day. About 10 minutes after leaving the dealer, then TPMS Service light illuminated on the dash (pre-inspection done at Orange County Ferrari... lol?). After checking in the manual, and checking the tire pressures the old fashioned way (a few times on the way home), I decided to just drive it home and have a local dealer look at it. Before bringing it to the dealer, I was cycling through the pressure readouts and it turned out the fronts (IIRC) were being read, and the rears were showing up as -.-.

I brought it into the dealer expecting them to tell me to install new sensors. However, they told me they couldn't get the 'old' TPMS sensors any more, and that they needed to install the 'new' TPMS ECU and sensors in the car (I think it was around $3500-4k). Needless to say, I told them ,|,,. I'm not sure what exactly they did, but after I got the car back it didn't register any pressures for the front or rear of the car. All I got was the TPMS {Service} light on the dash when I drove the car.


Fast forward to this week:

I bought a set of brand new Challenge wheels from a forum vendor, a set of RE050A tires from Tirerack (they were listed as OEM, along with the Mich's and Pirelli's), and a set of 315Mhz RDE-004 Beru sensors (dark brown) from Dubzdirect. I brought the stuff to a tire shop near my office and had them mounted up. The other night I got around to swapping the wheels around. This morning I finally had time to mess with the car and try to calibrate the TPMS.

I turned on the ignition, after the Check OK light illuminated, I held down the calibration button until the {CAL} light illuminated, then I started the car and drove around. The display went back to the clock (not TPMS Service light that I'm used to). After about 15 minutes, the TPMS Service light came back on. I pulled off the road, turned off the car, then went through the calibration init process again. This time, the {Cal} light was immediately replaced by a TPMS Service light once the car started up.

Is it possible the dealer did something to disable the TPMS when they had it? (would i still get a TPMS Service light?) Or is it possible I didn't order the rite sensors? As long as the tire pressures are over 25psi, wouldn't they still register and be visible through the menu if the ECU was able to read the sensors?

I'm so fed up with this system. For such an awesome car, it's a complete POS.

I really don't like the service department at my local dealer, otherwise I'd just go drop it off and tell them to Make It Work. I don't even want to schedule a time for them to connect their SD2 and tell me what they see. The next closest dealer is SF Ferrari (heard good things) but it's a real PITA for me to get there from Woodside.

In my opinion TPMS creates more problems than it solves.

Take the TPMS system on my 4Runner. The tires will last some 80K miles, the battery in the TPMS last about 15 months. So, there will be 10-14 years (based on current vehicle useage) when the system is telling me something is amiss, while the pressures are just fine.

I just hope the dash light burns out.....

 

I am getting this warning light on my 575 that stays on which as you can see from the attached photo shows a tire pressure warning light for the left rear, but at the same time it shows that the pressure is normal at 35 PSI (after driving), which is not low. So why would this warming light come on and stay on if there is no problem with the tire pressure? Is it possibly also checking the brake pads to see if they are worn past a certain limit or something?
