This one should work fine

 

Just bumping the thread - made some updates to the initial post with real world experience of the Schrader 29178/9 sensors (thanks LannyL81!), and clarifications on trigger tool compatibility.

 

Your statement regarding Schraeder TPMS is "patently false" in regard to programming with a magnet. I purchased the Schraefer TPMS from the place that has all the parts for your car for my 1999 C5 and programmed them with a relatively cheap magnet.

 

When was this? Did they look like this?

 

As he hasn't bothered to answer my questions, I'm just dropping back in to rebut rwlc5's accusation. While he may be correct in regards to the OE Schrader sensors of the same part #, the current versions matching the pictures in the previous post absolutely do not respond to a magnet. I verified with the two above. These are currently the only versions being sold most vendors.

Anyone with stock of the OE parts will be selling very, very old sensors, likely at several times the price of the newer design sensors. The early C5 versions have been out of production for around a decade. The typical shelf life for these type of batteries is 13 years.

 

One part number I haven't seen come up in this thread yet (unless I missed it) for the early cars is the Schrader 28006. I just bought 4 of these for my 97 and put them in to replace my original 27 year old sensors. Yes I made the apparent cardinal sin of putting them in before training them. The boxes are dated sometime in 2018 and were sealed so I doubt they are dead.

So far I have had zero luck training them with the Amazon 9 dollar gizmo or a large size common mechanics pen magnet. There is zero response. No honks.

In the event there is something wrong with these I do have my own tire equipment so it's not the end of the world, but certainly annoying for sure.

My next move is to find a stronger magnet? and then start somewhere other than the left front on the off chance that one is bad.

 

Assuming those are the old magnetically triggered OEM style, I was successful triggering my new old stock OEM sensors a couple of years ago with a magnet from a parts tray. The magnet was about 3” in diameter.

 

Ok, I can breathe a sigh of relief lol.

I was able to train them using a triangle welding magnet that I completely forgot that I had that was right in front of me in the garage the whole time!

They are still showing blank even after the honks but I'm sure that is because the car has not driven yet.

 

Sounds like you got it. This always worked best for me with the old type.

I did not want to dick around this summer when I replaced all four corners on my 99. with Schrader 29178. Piece of cake.

 

Another powerful magnet is the "donut" type they use in the 4L60E and some other auto transmissions. They're about 2-1/2" diameter, with maybe a 3/4" hole in them, and maybe 1/4" thick. I have several of these. I just put 2 or 3 of them together, then place them over the valve stem/sensor. Works every time......

 

Thank you so much for the Schrader 29179 info. I stayed late at work trying to reprogram my sensors using the magnet. It didn’t work. I’ll try first thing in the morning using the shops SnapOn TPMS tool to trigger them using the low frequency.

 

So the dic does not go to key fob training so can’t get to type pressure monitor training.

I press options until the DIC goes blank then hold the option key down but it goes to something apart from key fob training immediately. I’ve been told this might be because the receiver module is not working. Would that be correct?
If so does someone have a part number and photos of the 2001 to 2004 receiver?

 

I've read this thread's opening post several times. It differentiates between programming (which sets sensor parameters) and relearning/training (which pairs a sensor with the car). Questions:

• These sensors need to be programmed before training the car, right? I'm pretty sure the answer is "yes" but I'm just making sure I fully understand.

I have a friend with a recently-acquired 1999 FRC. My friend wisely wants four new TPMS sensors with his recently-delivered wheels to ensure proper operation for the foreseeable future. So far...

• Discount Tire (the tire installer) says they are unable to supply sensors that work with the C5, citing a lengthy backorder.
• My friend purchased these Autel TPMS sensors. Discount Tire was unable to wirelessly program them and they apparently don't have a physical cradle.

Has anybody successfully used these sensors in an American C5? If yes, can you provide the steps you followed?

 

I can answer most of your question(s) in exquisite detail. I'm struggling to keep my eyes open at the moment so check back in 24-48 hours. Sorry, have other projects going on at the moment and I don't want to provide info that may not be completely clear.

 

Not necessarily. I've tried to outline ones that are universal and do require programming (let's refer to it as configuration?). There are also several models that can be purchased that work out of the box. The most recent is the latest model from Schrader that supercedes the original 29178 part # that I posted a picture of in post #44 here. Another is the MoreSensor that was mentioned in the first post under the "Technical Compatibility" heading, third paragraph. So I have to want to continue the discussion by asking why you did what you describe next (buying sensors from AutoZone?).

Am I safe to assume that FRC is either a base model or a Z-06 that has had TPMS enabled? Because it (TPMS) wasn't enabled as far as I know in any Z-06 of this era. If it's not showing tire pressures under the 'Gauges' option on the DIC, it may not be enabled, and therefor won't let you train any sensors.

Assuming yes, what I can tell you with certainty is that Autel sensors are junk. Save your money. Though I don't do this for a living, a good friend of mine does and I've never seen an Autel branded sensor (on the dirty floor of their shop) that had contacts for cradle programming. The same friend has also expressed to me that the Autel sensors tend to live about 4 years max before the battery sh#ts the bed.

Additionally, I would remark that likely the only reason the Discount Tire shop was unable to program them wirelessly is because the tool they were using was either incompatible or required an update. This is what you get with retail tire jockeys. The only thing they excel at is mounting and balancing 8 tires an hour on cars that are less than 10 years old. If you're really lucky they won't cross-thread your lug nuts in the process.

One last question - what trigger tool was being used during the training attempts (magnet or RF)?

You can be the first. And maybe also the last.

This isn't rocket science. I've gone out of my way to try and help folks understand the underlying technologies. So forgive me if I seem confused and slightly annoyed when you go buying products that have never been mentioned here, and then ask why they don't work. Our cars are becoming antiques (my 2001 can be registered as an historic vehicle next year). Don't expect the snot-nosed punks jockeying tires to know anything beyond 15 years, because there aren't any gray-haired techs there to show them how to handle cars that were around before they were.

 

Update:

• My friend found a local tire guy who quickly and successfully programmed the sensors with a wireless device and then successfully paired them with the C5.
• When I asked what the tire guy did differently than Discount Tire, my friend replied "Probably, he read the instructions."
• The sensors are presently mounted in new Forgestar F14's and shod in new ECS02's.

I'll answer questions in line below.

It's important to note that I didn't do any of this; a friend did. I'm just helping him sort this issue and learn a few things along the way. I learned quite a lot about TPMS from this thread and my experience with my friend.

He bought the Autel sensors because he was in a hurry. You and I might have waited a few more days for parts to be delivered; he chose differently.

Good question. Since the Z06 wasn't offered until MY 2001, this isn't a Z06. FRC's were Z51-equipped Corvettes with limited interior options.

We noted the availability of TPMS on this car shortly after he acquired it.

I doubt that a four year horizon will be a problem, for two reasons:
1. My friend hasn't kept any car for four years. He likes to wheel and deal.
2. If he actually keeps this car for four years, it's *highly* unlikely that the tires will last that long. He'll have opportunity to replace the Autel sensors if desired, when he has more tires installed.

RF, as far as I know.

I'll let my friend know he's a pioneer!

I am highly appreciative of the work you've done. As noted earlier, I've learned a lot.

Perhaps I can help with the confusion and frustration. For the record, I didn't ask why they don't work. I asked if I understood the process correctly; you affirmed that I do, and I thank you. I also asked if anybody had used these successfully, and if yes, what steps they followed. I wish I had witnessed the shop's actions so I could help others by providing the steps. As Woody Hayes used to say, "Pay it forward."

 

Ah, sense is being made now. Another possibility that I've seen before is what I call "entitled capitalist" syndrome. This is where the service provider gets butt-hurt because you didn't buy the materials from them and so they go out of their way to not make said materials work.

Sorry, I didn't catch the complete story initially. I get it...

As I'm typing this I'm about to go mount 4 new skins on my mom's Nissan. I will be using the SmartSensor programming tool to clone the original (circa 2009) sensors so no relearning is required. The point I'm trying to make is if you know people with C5s (particularly early models), and also have other vehicles with TPMS, the SmartSensor tool will pay for itself. Additionally, maybe you could setup a TPMS "lemonade stand" near Discount Tire stores and possibly produce additional hustle as it will also program most sensors wirelessly.

 

I recently acquired a 2003 C5 and immediately put new tires on it. At the time, I did not think about replacing the TPMS modules and found out about a week later that only 1 of the sensors was working. I ended up purchasing the following from this company that I had purchased other parts from:

https://a-premium.com/product/2001-2...nsor-aptpms312

These sensors are supposedly pre-programed and guaranteed to work with the 2001-2004 C5.

Discount Tire installed the sensors for $10 per wheel (since I had purchased the tire there. $20 if not) and we were able to get them to learn through the DIC procedure with their tool. I had tried the magnet learn procedure and that did not work with these, so not sure if that is not a thing anymore or if just these sensors don't have that functionality. I've only had them in place for a few days, but so far they appear to be working fine and I am no longer getting the TPMS system error on startup.

Just thought I would throw this out there since this thread had helped me out with my purchasing decision.

 

Interesting, if you look up the fcc id on those they appear to be made by Tesla.

Two tire installers could not get more-sensor tpms to sync with my 2001 c5. Magnet method was futile. I took your advice and purchased an inexpensive TPMS Relearn Tool EL-50448. I reset all 4 wheels on the first try. Many thanks for your article.
