Here's why I think Discount Tire was unable to register your new sensors. I own the same TPMS tool that Discount Tire was probably using on your car...a Bartec Tech400. I have been struggling with this problem on my own Mirage for a couple of months!
Based on my own testing...I have come to this conclusion...
You can't perform a TPMS re-learn in a Mirage with any tool if you have a flashing TPMS light.
There's only 1 set of circumstances that will make the TPMS light stop flashing on its own without having to go to the dealership...
- The TPMS computer is functioning properly
- The computer doesn't "see" the 4 sensor IDs it has registered because 1 or more sensors are inoperable/missing
- You replace the inoperable/missing sensors with functioning sensors with the same sensor IDs already in the computer
For example... Guys who have winter wheels/tires with no sensors run all winter with the TPMS light flashing. Then in the spring, they re-install their summer wheels (with the original TPMS sensors in them) and the light suddenly stops flashing the first time they drive the car.
In your case, you have 4 new sensor IDs you need to register in the TPMS computer. But here's the catch with Mitsubishi that we have not known before. If the TPMS light is flashing for any reason, the TPMS computer sees a problem and one or more TPMS troble codes have been set in the computer. The only way to get that light to stop flashing is to have a dealer clear your TPMS codes and then do a TPMS relearn. Even though you have 4 brand new sensors that work properly, the TPMS tool can't perform the process because of the error codes in the car's computer. A $2000 Bartec TPMS tool cannot erase TPMS codes in a Mitsubishi Mirage.
I have been in this situation twice with my car in the last 4 years. Every time someone (other than the dealer) has tried to do a relearn in my Mirage (and my TPMS light was flashing at the time), it never worked. Discount Tire was able to do a successful relearn in my car once...but when I went in that time, my TPMS light was not flashing.
I currently have a flashing TPMS light in my Mirage, but all of my sensors are registered and functioning properly. I am unable to do a TPMS relearn in my car. I even had Discount Tire try their tool...and theirs also failed. My expensive TPMS tool is a worthless brick because the Mitsubishi computer won't allow me to do anything until the TPMS codes are cleared.
I just figured all of this out recently. I can't say it's 100% certain...but I'm pretty confident that this is what's going on. My car will have to go back to the dealer one more time. I hope to be able to talk to the tech about it when I go.
