TPMS question and LCDM
A friend of mine just picked up some new (used) wheels for his vette. They are Z06 style wheels, I have no idea if they are GM or other. They have tires on them and he is going to remove the tires and have his tires put on.
What problems might he have with TPMS? We don't know if there are TPMS on these wheels yet. If there are, will something have to be done to recognize the these different TPMS over the ones on his old wheels? If there are none, can his be transferred to the new wheels? Anything that he may need to know before he does the swap?
I also decided to check my codes the other day. I had a B2284 Battery #2 Fault on LDCM. What is battery #2? What might be the cause? I have not had this error returned after clearing it a few days ago.
Thanks

If the wheels are factory ones, there should be a GM marking somewhere on them. If no GM marking, most likely they are aftermarket (especially if they are chrome plated).
Most likely his TPS can be transferred to the new wheels - he will need a strong magnet and follow the proper training procedure to sync them to the car. If he doesn't know how to do the sync procedure, I can send you the steps. If there are sensors already in the wheels, you'll know it when you take the tires off - they will be readily apparent as they are integrated with the valve stem.

Thanks, I remember seeing something about this for the TPMS. If you can send/post the steps that would be great. I figured that we would be able to see the TPMS modules once the tires are off. We'll try to get this to go down all in one day. I hope the place we get the tires mounted have some patients with us. Thanks again.
Any guesses on the BAttery # 2 fail? This is on the LDCM. I see that I did not spell correctly in the title. What is Battery # 2? Thanks again.

1. Turn the ignition to ON.
2. Press the 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 the TIRE TRAINING message appears.
6. Press the RESET button until the IPC LEARN L FRONT TIRE message appears in order to begin the programming sequence.
7. Install the J 41760 (Magnet) over the left front valve stem.
8. The horn will sound, indicating the left front TPM sensor is programmed.
Important
If the horn does not sound after 15 seconds, remove then reinstall the TPM sensor programming tool. This procedure may have to be attempted up to three times in some instances.
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

The LH Door Control Module (LDCM) has two main power feeds (high and low), and one main ground. The low power feed (battery 1) is used to provide power for the LDCM logic and internal driver operation. The high power feed (battery 2) is used to provide power for systems that draw higher amounts of current (motors, lights etc.). For most functions, the LDCM will operate properly when vehicle system voltage is between 9.0-16.0 volts. The LDCM also monitors the voltage level at battery 1 and battery 2 circuits and can determine if the voltage level received is out of range. If the voltage level is out of range in either circuit , then a malfunction is present and a DTC will set.

Ken Shores,
If your friend's new wheels do have OEM sensors in them, he can use them with his car after doing the retraining procedure. I think, but am not 100% sure, that you could have multiple sets of sensors (i.e., if you had different sets of wheels/tires that you may swap back and forth) that, once trained, will interchangeably function without having to retrain each time.

Also, whether or not you can use sensors that came in the wheels depends on the year car they come from and the year car you are putting them on. Sensors from '97-'00 are compatible and from '01-'04 are compatible. If you put late model sensors on an early model car they will not program. Vice versa as well.
Also, if in the process of changing the sensors from your current wheels to the new wheels you move them too far from the car they will have to be reprogrammed even if you place them in the same location.

MarkC5 and all thanks for the info. I just got a text from my friend and he's on his way to get the old tires off his wheels. I'll share the info with him. What is the J xxxx magnet? Can any old magnet do?

The FOB has absolutely nothing to do with honking the horn during TPMS programming. The only thing the FOB and the TPMS system have in common is they use the same receiver. They function totally independent of each other.
