Hey guys I put my summer tires back on my Prius and register the tmps and came up with a code c2126 when I use the laptop it show all tire sensor are not reading any help would be great. My winter tire had tmps that I register to the car and worked fine I took them off and put summer tires on register the print out I had and now the system does read any of the wheels
I put in new tpms sensors and got the same code so I replaced the tpms module and cleared the codes and programmed in the four sensors again. I still get this code. Any ideas what it could be?
