2016 GMC Savana Service Tire Pressure Monitor System problem
 

I am having an issue with my 2016 GMC Savana. Every day 20 minutes into my drive I get the flashing TPMS warning light for 60 seconds it then goes solid. The dash warning display reads Service Tire Pressure Monitor System. When I query the tire pressures the right rear wheel always reads - -. Sometimes it is both rear wheels, sometimes one of the front ones join the party but always the right rear is included.

I have been to the local dealer multiple times and for hundreds of dollars all they ever do is relearn the sensors and send me on my way. 20 minutes down the road the light is back on

This past weekend I went to the tire shop and had all 4 sensors replaced and relearned. Once again 20 minutes down the road, right rear wheel trips the warning light back on, the left wheel joined in a couple minutes later. I am not finding any good descriptions of what or where the device that receives these signals is located. Perhaps a body control module?

Dealer doesn’t think it is a BCM because there are no other electrical gremlins going on.

I am at a complete loss has anyone else experienced this and if so, please share solution or suggestions.

Cheers

Weird.

Okay, if one wheel consistently alerts first, rotate tires front to back, relearn, and see if the issue follows the wheel move or keeps alerting the same corner.

Re read.

Ok. Yeah try what Cathedral Club suggests.
