Thanks!

 

I'm trying to determine which item I need. The Autel website (maxitpms.com) shows a Sensor M (Press-in) and a Sensor R (Screw-in). The sensor itself is the same, but does anyone have any experience or advice regarding whether the Press-in or Screw-in stem is preferred? Would one be more secure or capable of higher speeds than the other?

Here's the website: https://www.maxitpms.com/tpmscms/product2/798.jhtm...

Also, is there enough space on the valve stems for the color-coded rings?

 

It doesn't matter. I've used both types over the years on all my cars. I've never had a problem with one being less secured than the other. Unfortunately the color coded rings will not transfer over.

 

I used the screw type with no problem. No rings on mine, but I printed this and put it in the glove box.

 

Thanks gents!

 

Hi Friends,

Its old thread but hopefully some you are still around and still have AM.

I have 2009 DB-9 my sensor batteries went out. I did method 2 , all sensors are reading correctly, on smarttyre box 4 tires lights flares and goes off after driving few miles as its suppose to, left most light turns green , meaning all tire pressures are good.

BUT error message on instrument cluster " tire system fault" and error light in amber color TPMS won't go away even after months.

I read somewhere that dealer has to reset it? is that correct?

 

Dealer reset is only needed if you have new sensors with different identification numbers. If you are cloning, there is no need to reset. However, the Smartire system is unforgiving regarding tire sensor placement. Meaning you can have all the right identification numbers, but if they are located in the wrong position, you'll get a fault. When you reinstalled your sensors, did you keep the sensor in the same tire location?

 

If you're correct about placement @VAENG, then I'm the luckiest guy to ever clone his Smartire sensors. I found the sensor ID# tags in the trunk when I bought my 2006 DB9 and used those to create the Autel clones about 5 years ago. The tags were color coded, but the colored rings had long since disappeared from the valve stems after a couple of tire changes. I handed the 4 new (unmarked) sensors to the tire shop and they placed them randomly.

The first couple of drives after swapping, the system was slow to recognize the sensors and put up the warnings on the dash. After about 5-10 minutes driving all the warnings disappeared. The slowness to recognize disappeared soon after and never returned.

 

About 12-15 years ago I was able to purchase a Smartire programmer from a trailer supply store. When you connect it to the back of the Smartire module the system requires an assignment of a specific TPMS sensor ID to each individual tire location. So, if your system recognized the correct ID sensors in incorrect tire locations, that's great news because all the literature concerning the color-coded sensors and tire placement seems very rigid. Aston Martin issued Service Bulletin SB0297 in 2009, which might help Wildcat1212 troubleshoot.

 

Thank you all for the responses
turns out my problem was slightly different


few years ago when I was trying to disconnect smarttire box , the wire male connector on the back had broken in to two I had used crazy glue and it was working but during this time when I was messing around with sensor cloning (which btw was successful ) i must have damaged that connection as it separated again but I was just able to put it back together by just plugging it back but then I realized hmm this must be causing the problem.

I read on this forum that one can by pass TPMs if you just connect 3 of 4 wires together


on the vehicle side of the plug
red/blue mix : 12 v power supply
black is ground
red is TPMS system fault line error
white is low pressure error line

I thought that white must be fine as my 4 tire pressure light goes out after driving a bit and TPMs status light turns green

so fault must be with RED wire : which is TPMS STSYEM FAULT LINE


red and blue STRIP WIRE is power supply leave it untouched.

so what I decided is took a wire about 3 inch which was lying around, I found small connector pins in the garage I soldered them to two ends. Stuck one in black and one in red wire on vehicle side of the plug , wrapped it with electrical tape to secure it and BAM TPMS display error light on dash board went away.

I tested TPMS by partially deflating and inflating each tire and it worked properly.

mine are like this
GREEN : Front DS
Red: Front DS
Blue: Rear PS
Yellow: Rear PS

so sensor is not location specific

 

Your post reminded me about Redpant's Smartire TPMS defeat.

 

Yes it was inspired by those posts

this forum has multiple discussion

only difference here is I still have functioning TPMS BUT got rid of that annoying flat tire solid yellow light on the dash
