Smart Tire problem

[merle&louise]

I had a SmartTire monitoring system installed on my coach in October 2008. It worked great until last week. It would read the driver's side front tire but not the passenger side front tire. I was told to send the receiver to the factory for repair/replacement. It is under warranty so I'm not out any money!

Has anyone else had trouble with their SmartTire monitoring system?

I haven't had any problem with mine. It's reading all 12 tires at last check.

Ray,

Thanks for the response. I guess I just got a faulty receiver!

Thankfully, it is easy to replace it.

Hello Tuga,

I have used the Smartire system for over 3 years. Are you getting any error reading (E1) on the unit. If you are then the sending unit is not being read by the receiver. If you are not then there are probably two possibilities: 1. the receiving unit is no longer recognizing the sending unit, or 2. there is a problem with the receiver. I would try and see if I could "teach" the receiver that there is a sending unit attached to the right front tire. If that fails, then I would send back the receiver to Smartire. Over all it is a good system, and has saved me a couple of times.

Kim,

Glad to hear that you like the system and that it has prevented a costly tire failure. I'm sure that I just have a faulty receiver; I sent it to be repaired yesterday afternoon. The repair facility is in Junction City, OR.

How do you teach the receiver to recognize a sending unit?

Tuga,

It's a great system, but a little spendy and a PIA if you have a sender problem, since the tire has to be broken down. I had it on 2 previous plastic CC's and lost a signal from one tire. It was a battery problem with the sender. Hope yours is the receiver and not the sender.

Truk,

Glad to hear you liked the system. Like so many other diagnosis, it seems prudent to start with the simplest step first; so I sent in the receiver to be repaired/replaced at the suggestion of Newell. When it returns from the repair facility I will hook it up and see what happens!

I have already been warned to be very careful when breaking down the tire to access the sending unit. My tire guy told me that they have done this before, so that is good news. The sending unit is close to the valve stem on the inside of the tire.

SmarTire Systems was recently purchased (12/08) by Bendix Commercial Vehicle Systems - if the sale is approved by the share holders your warranty issues/questions should be probably be directed to Bendix or one of their distributors in the near future.

Tuga,

Your problem apparently has to do with the location of that transmitter on your coach. Of the 14 sending units I've had on my rig since July 2005, only the one on the right front wheel has given me a problem. It takes up to 15 minutes to finally decide to report in, then works fine. Please post any details the company gives you on what failed.

Ron,

The system worked perfectly from October 2008 until December 11, 2008, so I don't think that the location of the antenna is the problem. In fact, the passenger side tire "reported in" first before the driver's side when the system was working properly.

I moved the antenna closer to the passenger side tire yesterday before I mailed off the receiver and it still didn't work (I didn't however, wait 15 minutes for it to find the sensor). So maybe your diagnosis is correct.

Thanks for your help. I'll post the results when I get the receiver back.

Question: If the bus has 8 tires and the toad has 4 tires; why have you had14 sensors? Were the other 2 sensors replacing faulty ones?

Orren,

Thanks for the information on the buy out by Bendix.
