Driving yesterday and on the DIC up comes "service tire monitors". Whats up? (2010 GS A6)

 

Is it still showing today? Do you see any tire pressure readings in the DIC when you scroll? Have you done anything to the car like disconnect the battery?

 

Have tire pressures when I scroll the DIC. Words go away after awhile, but light on the dashboard stays on. Happened 3 days ago, then off, then on again yesterday.

 

No battery disconnects

 

Hmmmm......no definitive answer for you. Could be a spurious communication issue with the computer/sensors, or less likely, a bad computer or sensor. Wait for more input here, especially from BEZ06 since he's the expert.

Did you notice if any of the tire pressures changed while driving? You could test the communication by driving a few minutes while noting the displayed pressures then either add or release 2-3 pounds of pressure from one or more tires to see if they register the change.

Please let us know what happens. I try to watch these threads closely to keep learning. TIA

 

The generic fixes seem to be:

Drive over 20 mph for a few minutes
if that doesn't help:
Disconnect negative cable on battery for 20 minutes, reconnect & re-index windows
if that doesn't help:
Have dealer or tire store re-match sensors and car using proper tool

or just wait for BEZO6 to chime in...

 

Do you still have your OE wheels on the car???:

If you have swapped to a new set of wheels and didn't program the new sensors into your TPMS you'll get a "Service Tire Monitor" message.

Bob:
Put new front tires on 2 days ago at Discount. I'm pretty sure they did the Tpms correctly. No new wheels. I did get the message a few days before all of this and then again yesterday. The original time(few days ago) car was inactive, in garage for 2 days without driving it. ???

take it to the dealer and don't worry about it.

 

I have the same warning, however I purchased my 2005 used with HRE 19" rims. What do I need to do to fix this warning on my display?

Can I program the sensors or do I need to take it to Chevy or tire dealer?

Thanks for your assistance with this matter

 

I guess your wheels actually have sensors in them, is that right?

If so, it sounds like they may not be properly programmed into your TPMS computer in the car. If that's the case, you're going to have to have somebody with a TPMS tool do a relearn procedure to program the tire pressure sensor ID#'s into the TPMS computer memory.

Dealers are very poor at working with something like aftermarket wheels. I would take the car to a good tire shop to get them to help you.



I had a PM from another forum member recently that has HRE's and is having problems. Here's what he asked:



Here's what I wrote back to him:


So.....you probably need to have the sensors programmed, and it may be tricky with your aftermarket wheels.

You've been driving that thing if you're putting new tires on the front already on a 2010 - and that's good!!!

I assume that Discount Tire left your original sensors in the wheels - if so, there was absolutely no need to do any programming because they were already programmed in!!

If they mixed them up and put the sensor that was in the Left Front wheel in the Right Front and vice versa, the sensors would still work fine - just the DIC readout would be wrong (i.e., if it said the Left Front had low pressure it would actually mean the Right Front).

If they did try to reprogram the sensors, if they did it wrong it might knock all of the ID#'s out of TPMS memory.

If you started getting this problem a few days before getting the new tires mounted, then I wouldn't think it had anything at all to do with that anyway.

I don't know why your sensors would be acting up, but I think the first thing I'd do is to reprogram them into the TPMS computer memory.

You're under warranty, so I would hope the dealership would just do it for free, but I've heard of many dealerships wanting to charge from $10 to $100 to do the one minute procedure!!!!

I would take it to your local Discount Tire and I'm sure they'll do it for free.

Actually, you should be able to do it yourself on a 2010. The 2005-2009 require the use of a TPMS tool to trigger the sensors during the relearn procedure, but the sensors on a 2010 and newer can be triggered by changing air pressure. Take a look at the video below and you can see how to put the car into the learn mode, then instead of using a tool at each wheel you'd just let air out of each tire to trigger each sensor, and just like in the video, you'll need to hear a honk of the horn at each wheel (double honk at Left Rear) that confirms that the sensor was triggered and sent out its data and the TPMS computer received it and logged it into memory.

So.....you can do the procedure yourself - all you'll need is an air source to pump your tires back up after you're done.

BTW, although GM changed the sensors in the 2010 and newer C6's so they will trigger with the change in air pressure method, I've read that beginning with cars built in Jan 2011 they have removed the capability to use that method, and any cars built since Jan 2011 will require the TPMS tool.

Bob thanks alot for the info. I know a guy with the TPMS tool so I'll ask him to run around the car with it. And about my tires, 10K on the OE GY Run flats? Horrible. Replaced with Bridgestone Potenza Pole Position RF's.

 

Bob - Thank you very much. This is one of the few problems that I have with my newer ride. However, after 4 weeks I'm still smiling and enjoy driving it everyday.
