I got a code from the OBD2 the was C2126. I can read my sensor id via the car OEM but I can't activate them. All 4 tires are showing a red X. Any ideas?

 

Did you register the sensor ID's into the ECU?

 

it is the original sensors. I tried to scan them with my Autel TPMS TS601 scanner. Every tire shows a red x. When I run the diagnostic it gives me the code C2126. I can erase the code but it comes back. I'm thinking the control module. Any advice would be great. Also where is the module located? Google is no help.

 

Control module, receiver, sensors not registered, bad sensors, bad wiring.

Try resetting the system. See video below:

Thanks! For the life of me I can't find the TMPS button. Not in the glove box, under the glove box, or to the left or right of the steering wheel down low.
