Non of the TPMS in the tires are working so I want to stop the DIC from telling me to have the system checked.
Can I pull a fuse or something?
Thanks

 

I'm not 100% sure on his but I think you might have to have it shut off/tuned out of your BCM. I'm sure someone here can confirm

 

Not going to happen like pulling a fuse to shut down a module, since the RCDLR module is tied into too may systems like reading the fobs as well, and it would be the RCDLR module that your trying to bypass in the first place since it receives the TPMS sensors, and conveys that over to the BCM via the GM land bus.

Hence it would be like trying to bypass the ambitant light sensor in the dash by removing a fuse, hence that sensor is tied into the heater/AC controller, which again, reports that information back to the BCM via the gm land bus.

Also to point out, every time you go to start the car, the BCM checks all the modules on the GM land bus, and if even one of the modules does not come back with a good check, the car is going to throw codes.

Really, about the only module in the car you could by-pass, would be the VCIM by jumping the Gm land bus wires through it that the BCM is not going to throw a fit when it does not see it, but if you have On star in the car that needs the VCIM to be in play, then on star is not going to work.



As for trying to change the TPMS data settings in the BCM, it could be done, but would require a ton of code re-writing of the BCM firmware to start with, since the TPMS information is used to too many other systems of the car as part of there checks.

And no, you can't shut down the BCM, since it needed to trigger the ECM to allow the car to start and run in the first place.

So to solve the problem, you just need to pony up the $100 that is going to cost to replace the TPMS sensors in the tires that there battiers have died, with New TPMS senors with fresh batteries isntead.

As for how to tell if the batteries in the TPMS sensor have died, and not just a programming problem that the RCDLR receiver just needs to relearn the TPMS instead. If the RCDLR is giving you 00 readings then it a programming issue and the TMPS just have to be relearned to the car. If you get XX instead, then the batteries are dead in the TPMS's.

 

LG box, or there is a place you can mail off your BCM and get it programmed out, but no easy way to disable it.

 

Wow what a fantastic, informative, and knowledgeable response, thank you so much for all that info. you sound like you know what you’re talking about, so I’m going to accept that answer since I don’t know Anything about any of those systems. The TPMS in the tires are brand new and I and the dealer have tried to program them several times with no luck.
I think I got ripped off by China. Even though they had GM on them.
I guess I’ll have to live with them till I change tires.
Thanks,

Try going to Discount Tire to try resetting the sensors. They have the latest equipment and do it several times daily. They can check serial numbers and battery life too. A possible concern is the scam where dead sensors are being sold as new. Another thing to check is if the sensors are the correct ones for your car. Export C6's and all C7's use sensors that operate on the 433 MHz band while the domestic C6's use 315MHz.
In the future, you can teach the RCDLR the sequence before mounting them and verify the battery life. Both Titan and Orange Electronics have cloneable sensors, which allows you to capture the serial numbers from your current/previous sensors and transfer them to the new ones, effectively giving you two sets to make wheel/tire swaps without the need to relearn.
If you can't get the sensors to work and still want to get rid of the DIC message without installing another set before your next tire change, then buy new sensors (check them and learn them before proceeding) and put them in a sealable container that you can pressurize to 30psi and put it in the car. The RCDLR will report them as 30psi and clear any code history after 100 ignition cycles. When you change tires, you have sensors ready to use.
BTW. you can change sensors without having to take the tire off the wheel or lose the balance. It only requires breaking the bead enough to fit a hand inside.

 

To add to the above, there is two different TPMS for both US cars, and two different TPMS sensors for the Export on the C6 for a possibility of 4 different type TPMS's.

So the 2005 to 2009 uses one type (either us 315MHz or export 433 MHz),

While the 2010 to 2013 uses another type (either US 315MHz or export 433 MHz.

Hence you can't use a tpms for a 2009 (or early) in a 20013 (or later car, and visa versa, as well as the wrong MHz tpms ) since the RCDLR in the car will not register it.

Since you list that you are in the USA, lets bank that you need the 315mhz tpms, but if you list what year vets and the TPMS numbers, we can tell you if you have the correct TPMS's to start with to match your car.


2005-2009 Corvettes use GM Part # 25758220 sensors which are GRAY in color.
2010-2013 Corvettes use GM Part # 15268606 sensors which are GREEN in color.

 

Thanks and great idea about the extra sencors in the car.

Thank you, the ones in the tire are grey, and have the GM on them.
I will have them checked again.
