Tire Pressure Sensor+ New Rims= headaches

I have done alot of research on this, and this is what I have learned.
1. From what I have read that is must be done at the dealership and you must have the codes off of the sensors.
2. Built into the valve stems.
3. Yes, as long as they fit into your new rims.
4. No, as far as I know the car only recognizes one set of sensors.
5. No, see 4.

 

eBay Motors: TPMS Tire Pressure Sensor Toyota Prius Scion TC (item 310060074549 end time Jun-24-08 16:17:40 PDT)The code should be right on it.

 

Did your tire dealer install Toyota Prius sensors? Hope he didn't put on some cheap set that doesn't communicate with the Prius.

 

It's kind of unfortunate news for me to hear that the system only handles a single set of sensors. I was hoping to have separate sets of summer and winter rims and tires.

 

There are programmable sensors in the marketplace that can be programmed to duplicate the stock sensor id numbers. I am in the process of setting up a second set of tires (winter) with cloned sensors on the second set. If it works as advertised the Prius will not even know that the tires are being swapped, assuming air pressures are the same on both sets. If the on board Prius computer does detect a pressure change with the change, a simple reset of the under dash TPMS button should do the trick

That's about all I know at this point. I'll post details as I complete the process.......

 

There is also an ATEQ Quickset module that is designed to help swap sets as long as you know the new set's ID's.

ive had problems having my wheel sensors programmed at various shops.

the shop expects the "set" button to wirelessly read the tpms serial numbers, this does not work. and p** bo** kept me in the waiting room for them to figure out why they were having a ECU communications failure, and this does not work and it is not true

the second shop expected the prius to be able to read its tpms serial numbers wirelessly but you have to drive 7 miles or so. again this does not work and this was not true.

the gen 2 prius requires the scan tool to be connected to the OBD II port

the tire installer goes to each tire and holds the reader to the valve stem and waits for the tire to be read. even though the ODB II TPMS scan tool has a ODB II connector on it, they don't even try to connect it to your car!!!!

once this is read, the scan tool is inserted into the OBD II port and the tire installer :
selects read serial numbers from ECU
erases serial numbers from ECU
read serial numbers from scanner
write serial numbers to ECU

this takes about 5 seconds to write to the obd ii port. any tire installer that tells you to go to the dealer doesn't know the older TPMS
systems had to be programed via OBD II port and thinks your car has to go to the dealer

if you need a replacement tpms sensor , amazon sells the VDO SE10002 REDI-Sensor and it works fine

 

I now have a set of winter wheels which duplicate the four OEM TPMS ID's. The on board ECU will now accept either set without ANY reprogramming or resetting (assuming the same tire pressures are run on both sets). The process is pretty simple, but I thought I'd share the path that ended up working for me.

It's important to begin with choosing your installer and asking which brand of cloneable TPMS sensors they are equipped to program. There are several brands of programmable 315 mhz sensors, some of which require proprietary equipment to setup. I ended up with Standard Motor Products TPM82A sensors from Amazon @$30 +/_ from Amazon.

I had the dealer print out the ID#'s of the OEM sensors. I found that many OBD scan tools were unable to penetrate Toyota's menu system to retrieve this information. Fortunately our dealer was happy to retrieve the info for a reasonable $25 charge.

The sensors were programmed by the installer before they were installed on the rims, a process which only took a few minutes. All they needed was the list of sensor ID numbers, there was no need to hook up to the Prius with an OBD tool or to scan the OEM units on the car. Nothing was changed in the car at all.

All that was left was to install the sensors in the new wheels and to mount and balance the tires. The shop that did the work charged $75 for the complete installation, including the cloning of the new sensors. So for $100 plus the cost of the wheels, sensors and tires I now have two interchangeable wheel sets that require nothing more than a jack and a lug wrench to change.

(In the not too distant future Tire Rack expects to offer TPMS cloning on tire and wheel packages if you can provide them with the sensor ID#'s. However, since they do not sell the Nokian tires I was looking for I ended up buying the components from three different sources and bringing them to my local installer.)

 

I replaced the 15" wheels off my Prius Plug In with the 17" Persona wheels. I ordered four Continental DWS 17" tires, along with four Toyota or compatible TPMS sensors. I took the wheels, tires and sensors to a local tire shop I've used in the past. After install, they notified me they were unable to code the TPMS sensors to the car, and suggested I take it to a Toyota dealer. My Prius is due it's 10,000 mile service in a couple of weeks, and hopefully, they will be able to code the new TPMS sensors to my car. I've dealt with The Tire Rack many times in the past, I feel confident the TPMS sensors they sold me are the correct ones.

 

This is a novel idea I guess no one has thought of before. I remember that there are programmable "dummy" sensors but never thought about programming to duplicate! (I guess you could call me a dummy!) Great idea and thanks for sharing!!!!

SCH-R530M ?

 

Since the change from 15" to 17" sounds more like a one time thing, it's probably not worth it to look into the ATEQ Quickset. I wouldn't be worried about any issues either....

SCH-R530M ?

 

TPMS fun facts
---mandated safety feature by congress
---If working correctly tire must lose 28-27% pressure to trigger sensor aka dash light
---tire dealers and car dealers charge extra to fix and or reset the them
---if you change tires or rims sensor will need to be checked or reset
---when outside ambient temp change sharply (u know like fall to winter weather) may trigger sensor due drop tire pressure.

IDK
guess I was okay before TPMS and just lazy and like to check my individual tire/rims/pressure during weekly care maint

After looking on TIS for about twenty minutes, I'm coming up short. I don't see any procedures for "auto learn" type programming. Looks like the Dealership will have to do it. Have them break the tire down and write down all the ID numbers or try the TPMS ID scanner to retrieve the ID's (they should have that SST-00002-TTPWS). As long as the sensors are 8 digits (IIRC) they should program.

 

The dealership can easily print out a report with the ID numbers. My dealership charged me $25 for this service. These ID's may then be programmed into replacement (or duplicate) sensors using the programming tool for the particular replacement sensors. No breaking down of the existing tires is necessary to get the information, it is accessed through the OBD port and dealer software.

 

Why go to the dealer?

You can get the TIS Tecstream mini-vci cable and connect it to you laptop for a mere $25 delivered.

It allows you to read the ID numbers of the original TPMS sensors and have them clone them for the new tires.

This thing gives you access to nearly everything that the dealer has, except "on line" access.

 

Noticed one of the Amazon reviews mentioned that it worked with Vista, but not XP. I have a legacy Windoze machine that has XP and Macs. Could not find any system requirement specs or manufacturers page to see if software might work on newer Intel powered Macs. Anyone tried this with a recent Mac?
