TPMS Relearn Question
For a bit of background, I've been having issues having new tires installed, and have been going through several rounds of having tires installed and uninstalled repeatedly. After the fourth go-round, my left front TPMS was reading 5 lbs. high. I reprogrammed it, but did not complete the procedure for all tires because the magnet wasn't strong enough and only worked for the first wheel after placing the magnet just right. Now, I am getting the Service Tire Pressure Monitor Sytem message, and all tires read "xxxx". Is this because I did not complete the procedure for all tires?
I could have sworn that many years ago when I had to re-learn a monitor, I only did one wheel, and did not have this problem, but I could be mistaken, and had to do them all then, too.
Oh, and one more question: I previously used a speaker with a neodynium magnet on it, and I saved the speaker for future use, but I now can't find that speaker. If I can somehow go buy a small neodynium magnet somehere, would that be strong enough?
Thanks in advance.

I thought I had a strong enough magnet and was having a tough time getting all sensors initialized. I decided to buy a magnet from Amazon designed just for this procedure.
Got it, tried it, and it worked perfectly.

Did you follow the procedure exactly?
Programming TPM Sensors
Tool Required
Tire Pressure Monitor (TPM) System Programming Tool Tire Pressure Monitor (TPM) System Programmer
(TPM System Programming Tool means "magnet" to ordinary C5 owners!)
Important: Make sure the vehicle has been stationary for at least 2 minutes before attempting to program the TPM sensors.
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.
Notice: If the TIRE TRAINING message cannot be displayed, and the IPC is functioning properly, check if the BCM is configured with the correct RPO codes. Refer to BCM Programming/RPO configuration.
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 Tire Pressure Monitor (TPM) System Programming Tool 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.
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 Cancellation
1. The programming mode will be cancelled if any of the following conditions are met
- The program mode is exited through the DIC.
- The ignition is turned to OFF.
- All four sensors have been programmed.
- The TPM system has been in the program mode for longer than 2 minutes and no sensors have been learned.
2. If the program mode is cancelled with less than four codes stored, the receiver will only accept the codes programmed up to that point.

Thanks, guys. Just now used a stronger magnet and was able to complete the procedure on all 4 wheels. All is good now with the TPMS. 
The saga with the new Continentals, which how I encountered the TPMS issue, is a whole other issue!

To plainly state it for anyone else reading: YES, you need to do all four wheels!
The procedure erases the sensor information and replaces it with the new, 'learned' information.
If you don't complete all four wheels, the system will be confused and show an error until you start over and complete all four.
Also important, the tires must be done in the order listed. Any other order and the system will work but the tires will read out in the wrong order.
My AE had the two front TPMS sensors switched (Right front was done first) which was very confusing. The car told me the LF needed air, I'd check it and it was fine.
It was only when I checked all the tires that I discovered the actual problem.

I could have sworn that way back I only did one wheel, but I guess I was wrong, as indicated by my recent experience. Goes to show you should never rely on your memory and instead document everything.
While we're on the subject, does this mean if in the future I rotate the two front wheels with each other, for some reason, then LF reading on DIC would then be for RF wheel?

I'm just a ordinary C5 owner and a bit slow in understanding technical mnemonics, so if I could ask for your time, I would like to understand what IPC, BCM, RPO, and J41760 are or means.
I have installed ACDelco TPM sensors (#25773946)and can't get them acknowledged with the use of a magnet.

BCM = Body Control Module
RPO = Regular Production Option
J41760 is a magnetic tool used to reset some TPMS (Tire Pressure Monitor Sensors)

Sometimes that’s not all precise placement of the magnet is required! I just went through this ! After Les Shwabs lol had tried their device lost signal 4 times he tried saying somethings off in my tpms absolute bs ! Anyways I brought it back to my tire shop I had the new tires put on at because my tire pressure was reading opposite sides after a blunder mixing up the sensors! However during the relearn process the same thing happened again! We were scratching our heads then it hit me ! I’m using a flow forged wheel ! I recommend taking the magnet and placing inside where the spokes are and sure enough the metal was just block the pull from the outside diameter! Beep , Beep All the way around all reset! Good luck ! You have to the relearn process above 1st off !

I really tried hard to make them work with the magnet but no luck. Finally took them to the local tire shop and they got them recognized. Tire shop says that that happens sometimes and questioned whether my magnet may have not been powerful enough! They have a point and so do you. Well had I known that the tire shop only charges $12 I would have not wasted all the time and gas running around looking for a magnet. Well at leased I save quite a bit of money with the sensors ($46 set of 4) and broke the bead using a 2x4 and a short piece of 1x6 and installed them myself.

I have an old JBL car stereo speaker laying around that works fine for the rare occasion where I've had to do the TPMS reprogramming (maybe 3 or 4 times over the last 20 years - pretty much just whenever I get a new set of tires!)
It doesn't have to be a special magnet - just a strong enough one
