I keep getting a SERV. TIRE MAN. SYS or something like that and it sets the check engine light off as well. What the heck is that?

 

I'm not sure why the SES light is going off but your tire sensor issue could be due to a dead battery in one (some, all) of the tire sensors-it would help to know what year your vette is (I think the guys here say the life of the sensors is about 5-7 years). Three of mine work and one doesn't so I get that error quite often. You can just get new sensors or replace the battery in your current sensors. There is a thread to show you how to do so...just search
Good luck

 

Did This problem just start? Or have you always had this error?

It could be as simple as reprograming your Senosrs. Very easy to do. Of course it could be a failing battery in one or more or your sensors.
Another forum member had posted these instructions.

1) Turn ignition on
2) Press "Reset" button in order to clear any IPC display warning messages
3) Press and release the "Options" button on the DIC to scroll through the display options until the IPC display is blank
4) Press and hold the DIC "Reset" button for 3 seconds
5) Press the "Options" button again until TIRE TRAINING message appears
6) Press "Reset" button until the IPC "Learn L Front Tire" message appears in order to begin the programming
7) Install the J41760 Tire Pressure Monitor (TPM) System Programming Tool (large magnet will do) over the left front valve stem
8) The horn will sound, indicating the left front TPM sensor is programmed (if this takes more than 15 seconds, pull magnet back and try again, it will give you three tries. Then you must start over)
9) When the horn sounds, proceed to program the next TPM sensor in the following order as directed by the IPC messages: -Learn R Front Tire -Learn R Rear Tire -Learn L Rear Tire Programming can be canceled by turning ignition off, waiting 2 minutes with no sensors being learned, finishing all 4 wheels or through the DIC. If the programming is canceled with less than 4 sensors learned, it will only accept the codes programmed up to that point.


good luck

 

Shes a 2000 FRC. And well, for the most part the problem is constant but it does come and go.

 

Sounds like you have a failing battery in one of them..You can try to reprogram.. Its free!!

 

I would imagine that you have a dead battery in a sensor.

 

I can rebuild your sensors if you have the time to get it up on jackstands and keep it there for about a week and send me yours to rebuild

 

I bought a set of new sensors from GM for my 99 because I got tired of pushing reset.

One of them shows 3 PSI too low

 

Yea I have noticed they are all not 100% on the money

 

Don,

When you say rebuild, what else do you do other than replace the battery?

 

How large does the magnet need to be? Refrigerator magnet? Anything specific you bought for this?

 

I just programmed a new set on my car. I used an old speaker magnet.

 

Only the battery, thats what usually goes bad unless the acid in the battery has leaked out and shorted out the sensor (which I have a whole box of those)

 

how much do you charge?????????????

 

Does not have to be to large. Get one from Raido Shack.

 

Please pm me for more info.
