All Dealers did not buy the MB adapter for there OBD III to work on the Crossfire. Chrysler let dealers sell the car even if they could not work on them. Big mistake..

 

Have you tried Walmart or just plain tire sores.

 

NOT a chance in hell..

You have to have the DRBIII with the crossfire application software.

 

What brand?

 

There is much info on Crossfire TPMS in this thread & "TPMS...the Basics" especially by 180 & KDW4Him. Our cars have a unique system requiring a specific type of TPMS sensor & the Chrysler OBD III scanner w/Crossfire adaptor to plug in to car and a Crossfire software card to plug into scanner, & the round magnet tool used at the valve stem of each wheel to complete the process.


It is strange & sad that those dealers don't want your business, they could charge an hour labor for a 15 min. job (but, again, your sensors must be OEM, "Schrader", or compatible.
(here is a thought: maybe Texas Dealers had to "eat" so much in labor charges when they had to "farm out" convertible top replacements, because Corp. didn't pay a fair rate, (Texas being a "covered State of delivery"), that they would rather just turn them away. Or maybe; this German car scares the heck out of their "technicians", LOL.

 

Wow, obviously I didn't know that. I do have the magnet for triggering the wheel sensors, my 2002 town and country was one of the first things with tpms, and I did some work with them. I will have to read more about them.

 

Yeah I got the DRBIII "notebook computer" - Amazon sensors- and magnet. No one had ever said anything about TPMS on that system.. but come to find out the SLK didn't have pressure sensors.. so no "copycat" version to work with on the computer. Can access other modules on the car though. Still need to run through all the other available versions on the computer to see if just maybe another model might have and communicate with it..

 

How much did that set you back? I would love to get a real DRB-III tool, but not for a couple thousand $$.
I guess this sums it up, correct?

With my van (and the Jeep Grand Cherokee) you initiated it via the EVIC in the overhead console. What would be amazing, if you could hook one of those up to the bus, and initiate a reset from it.
Also, while I'm dreaming, the Grand Cherokee EVIC would show individual pressures and tell you which one was low or high, the T&C would say 1 high, or 2 low, but not tell you which, even though you program them to a location in the same process.

 

Your link.. finally an article that has it right.. LOL. A forum member that did a V-8 swap ended up selling his car.. and used this for the conversion to make the modules all happy.. sold it for $600. Which wasn't a bad deal at all when you look at Ebay offers on them..

Those "kits" that have their own screen and show each tire and pressure would be tempting if we had a decent place to integrate them into the consol..

 

Jeep Grand Cherokee WJ - Tire Pressure Monitor Systems Has some good info. My next junkyard trip I will grab one form a van or jeep, you never know. I was always going to try a jeep one in my T&C to see if it would work and show individual tires.
I believe Chrysler started down this road because of the Prowler initially.

 

I don't know of anyone there, but I had a similar problem in Las Cruces, NM. Got the TPMS sensors at Discount Tire but they and my usual mechanic couldn't program them. The Chrysler dealer is the only one in town with the correct programmer. I can't believe all those dealers in your area wouldn't work on it. I'd guess you'll never be buying a car from any of them! Might check with the Mercedes dealer to see if they can handle it. I also have a Sprinter-based motorhome and got very good service at their dealers all across the US (NM, Colorado, Boston, etc), even though my RV has a Freightliner nameplate. Good luck.

 

The SLK320 does not have TPMS but the 350 should. Do both use the same "reader tool"? Donno and could the 350 reader "talk" to the crossfire module? Probably not. My dealer charged 1/2 hour to program the car to the new sensors.

 

can someone explain the #2 wire trick referenced above?

Hi bluecoupe, That's an even better / clearer "How To" than what is on the forum. Nice job finding that . . .

 

I have a multipart question here. Assuming I want to get my TPMS working again instead of disabling.

1) how do I know which monitor is dead? I would plan on replacing all Of them perhaps with the next set of tires as it seems the concensus is 10 year life.

2) Does the monitor need to be installed prior to the programming or can they be programmed then installed?

 

1. You don't. You must replace all 4.
2. They can be programmed after installation, but finding any place, including dealers, that can do it will be very difficult.

3. Where are you in Alabama ?

 

There are tools than can test/detect the transmission from them, so you can find out which one(s) aren't working assuming that the light isn't on because of over/under pressure.

 

Even if you can determine which sensor has gone bad it would only make sense in most cases to replace all 4. The reason is that the sensors generally fail due to the battery getting weak. If one battery has failed the others won't be far behind (especially if they are 8+ years old). If you just replace one at a time you will get the pleasure of paying for TPMS relearning each time. Many dealers are now charging an hour of labor for this < 15 minute job. I think you could relearn the sensors before installation by just triggering each sensor, one at a time with a magnet, within transmission range of the car, when called for by the DRB III. Since the MIL doesn't indicate the specific tire location, it won't matter where those sensors wind up once mounted. All that will matter is that the car's computer knows the discrete IDs transmitted by each sensor. But you might have some difficulty getting the Chrysler dealer to do the relearn without the sensors installed. And, since the Crossfire has to be connected to the DRB III, it would make no sense to relearn sensors and then install them. I'm on a 10 year expected tire replacement cycle, so if I want to keep the TPMS working, I'll just plan to replace them all next time I need tires.

 

TPMS wasn't mandated until 2008, so actual life isn't that well know yet, but on my 2002 Chrysler Town and Country, I had to replace 2, and 1 was for a valve issue, not a TPMS issue. The other 2 still worked 2 months ago. It was on the road about 13½ years and 120,000 miles. And they only transmit when vehicle is active or 1 hour after parked (I think) So the battery is basically unused if vehicle is stored. But I do agree with Rob M, I also may pursue replacing all at next tire change since I will probably have the car long enough to need to replace them anyway, and I will probably NOT need to replace them twice no matter what, so might as well do it all at once.
