Maestro question

TPMS sensors were working fine for me. Had new TPMS sensors installed because one went bad. Replaced all 4. Now they are all showing up as N/A. The gauges have always and still do work. Running a Pioneer head unit. I’ve validated the PID’s multiple times, doesn’t really confirm that it’s done but instead the screen just changes. I’ve also done multiple hard resets for the Maestro module. Not sure how to get my new TPMS sensors to connect? They are Schrader EZ sensors and I had them installed by Discount Tire and I’m getting no error from the truck. I find it hard to believe that the new sensors would work for the truck but aren’t being picked up by the stereo but here we are. Could the resistor really be the issue just based on new sensors, especially when it worked 2 days ago with the old sensors?

 

Have you contacted idatalink to see what they say?

 

Yep, just got off the phone with them. He was surprised that the master reset didn’t work. I’ll have to dig out the harness to provide a version number. Asked about the resistor swap I read above and he said it’s a possible solution. I’ll have to get to it and get a solution. I’ll circle back.

 

Any update?

i have a backward issue on my setup. I have tpms reading but nothing else. Even after i set obd2 communication to Always Enable in the maestro menu.
Not sure what’s going on here.

 

Update:

i figured it out. Got everything working now.
Had to run 2 extra wires from the 28pins of the TO2 harness to the factory obd2 port.
on the 28pins of the TO2 harness, there is a Solid Red with brown and Solid Yellow with Brown. These are the CAN High and CAN low data. On the factory obd2 plug it is Pin 6 and Pin 14.
The Red/brown from TO2 harness will need to tap into Pin 6 of the obd2 plug.
The Yellow/brow from TO2 harness to Pin 14.
You should have Pin 7 occupied with the Grey/Red wire from TO2 harness and obd2 plugged in.


This is Pin 7
Pin 6 is the next one to the right and Pin 14 is directly above pin 6.

 

My TPMS, which worked for a year stopped yesterday. Gauges are fine. Weird stuff, I was going to call IDATALINK but thought, let's see if there is a new firmware.



Immediately after the update (so glad I bought the Bluetooth version)

 

I always check for update anytime i buy a radio or electronic that have firmware. It makes thing easier.

 

A year ago when I installed it I updated it to the latest firmware. Why would that fully functioning firmware stop working? Makes no sense.

Since it stopped working, I looked for new firmware, & installed it. It's weird that it stopped working.

 

I’d imagine over time it gets buggy.
