    Hello all, not sure how to explain this.

    My TPMS is acting up since i had an aftermarket stereo installed. I am using a PAC rp4-ch11 module with the stereo to use my stereo controls.

    Everything works great except for the TPMS randomly stops working.


    When I started driving after the stereo install, only the drive tire showed on my tpms screen. Then after 15 min, the driver rear and front passenger came back on. So i'm like cool, its just syncing up. The next morning, All tires were back on!

    But yesterday, when I drove, the rear passenger stopped working. But i left the car off for a few hours and when i came backup they were all up and running. Last night, the front passenger turned off, and this morning, it's still off.

    So could it be electronic magnetic interference?

    Or do i need to update the PAC module?

    Or my stereo is just a piece of crap and the canbus does not like it?

    Any ideas or assistance?

    I've been researching and it looks like it's happened to others but i dont see a resolution yet?

    Thank you in advanced.
