I had my two front tire sensors changed with a reconditioned Mazda sensor l purchased myself since l couldn't figure out which one was bad, and l also bought the EL-50448 relearn tool in hopes of relearning the new sensors. How do I get to the relearn mode on the dashboard of my 2010 Mazda 3 A?

Thanks

Hi,

I'm not familiar with the tool you purchased. The TPMS registration can be done with or without a scan tool. Pic 1 explains how to do it without.

The remaining pics are directions using a scan tool.

Take a look through them and let me know if you are comfortable trying them or if you have other questions.

Take care,

Joe

See pics below

Note: I just looked up the tool part number you mentioned. It appears to be specific to GM vehicles. Please understand, I may not even be looking at what you have, but thought I would mention it.

Thank you for replying. I already the first instruction by driving the car. That didn't resolve the light going off. As for the VXDAS EL-50448 Auto TPMS Reset Tool, it was recommended by Mechanic Base. Com. “The reason this makes it at the second place of our list is the simplicity it offers. With just a click of the button, you can begin testing your car pressure. If you are new to TPMS tools then this is the right model, to begin with. Operation is through a simple three-step process. Firstly, you set the device at Learn mode then place it near the sidewall where the valve stem is. Once you press the learn button, the sensors will be reprogrammed. The TPMS tool is compatible with most GM cars, but you can still use it for an Audi, Ford, Honda, BMW, Mazda, Mitsubishi, Subaru, Renault, and Toyota. This is because the device is compatible with all tires having 315 and 433 MHz TPMS. The downside is that the device does not work with trucks”.

Hi,

I read through your post regarding the scan tool. When they indicate you place the scan tool in the learn mode and next to the tire to reprogram the sensor, I'm not following.

My old TPMS tool was used like that, but I had to do what they said to learn the info from the old sensor and then reprogram the new sensor using that info. Am I reading that correctly or could what I'm suggesting being what is meant? I ask because you have to have the old sensor info to reprogram or program a new one.

Let me know.

Thank you for replying. I do have the old sensor, but l didn't for your instruction. I just placed the tool by the new sensor. Can you please elaborate more on the way you used your tool so l can try that option? Also, do you know if there are sensors already programmed that l could buy to avoid relearning?
Thanks

Hi,

In most cases, a new sensor won't be programmed. With my tool, I have two ways to do it.

The easiest thing I found was to remove the old sensor. The tool had a slot to place the old sensor. Then, I would copy the info from the old sensor. Next, I would install a new sensor in the same place and press program. The tool would then program the new sensor to the exact settings as the old one.

Also, if the old sensor was damaged and nonfunctional, I was able to gather the information by identifying the part number on the old sensor.

If I understand, you have the new sensors installed and are placing the tool near the valve stem and pressing program. There is nothing to program if the tool doesn't have the info saved. On the other hand, I may be totally wrong with how you are doing it.

The third and last technique was if there was a nonfunctional sensor and no part number. If that was the case, I was able to select a general frequency for sensor programming, connect to the data link connector, and then program the TPMS module to recognize the new sensor. I always made that my last-ditch effort.

I tried to find a pic of the old tool I had and can't find it. I have updated and the new one works differently. I attached a pic below of a different tool that in general appears the same. The slot that I circled is where I would first place the old sensor to copy it, remove it, and install and program the new sensor.

I hope in some way this helps. Let me know.

Joe

You are correct in the statement in the 4th paragraph of your response. Yes, I saw the Relearn tool you attached, but l can't afford that so l went with the lessor tool after reading the reviews and instructions. I am not sure where to go from here. I will keep you posted.
Thanks again.

Hi,

What do the directions indicate as far as programming? There has to be a way it's done. Also, is there a customer assistance number you could call? I found their website, but where it says contact us, they want an email. See pic below

Let me know what you find or if I can help in any way

Take care,

Joe

Hi Joe,

Here is the instructions:
When using the device ensure that the sensor re-learn procedure is carried out after remote control door replacement, tire rotations, and tire pressure sensor replacement. Relearning is done by first placing the car at parking then through dashboard settings choose the TMPS to relearn mode when using cruise. The TPMS will flash twice after you hear the car horn. This is the indication that the learning mode has being entered.

Hi,

From a person that has been using multiple scanners over several years, which makes no sense to me. Are you able to set a TPMS to the relearn mod on the dash? Also, the horn indicator of successful relearn is a GM thing. I'm not sure that Mazda does it.

Are there any phone numbers for customer assistance on the directions or any of the paperwork that was received with the tool?

I am not able to set the TMPS Relearn mode on my dash, and the company is located in China with an email address only. I haven't gotten a response yet.

Hi,

Okay. I suspect we need to wait for a reply. The directions they provided are nearly useless, but that isn't uncommon. Was it shipped from China? Is it something you can return?

Let me know.

Joe

Turn on the ignition. If you have a keyless start Mazda, press the Start/Stop button but don't press the brake pedal. All the instrument cluster lights, including the TPMS warning light (tire with exclamation symbol), will turn on press the TPMS switch on the left side of the dash next to the steering wheel. Continue to hold the TPMS switch pressed until you see the TPMS flashes twice.
Soon after the TPMS light flashes, you will hear a beep. This is confirmation that the TPMS light on your Mazda has been reset.

Hi,

I noticed we haven't heard from you for a few days. Have you been able to make any progress? I'm interested in knowing if you were able to get the issue resolved.

Hi Joe,
No, I haven't. I am researching whether l can buy a preprogrammed remanufactured tire sensor on eBay. Some sellers state that you can install them to drive for about 10+ minutes to reset the code. I emailed a seller, and I am waiting for a response. Have you heard of preprogrammed sensors?
Thanks,
Hannah

Hi,

A TPM sensor can be programmed. Also, as long as someone knows the frequency each works on, yes it can be done.

Let me know how things turn out. Also, let me know if I can help in any way.

Take care,

Joe
