check engine light and tpms

[dickeyphoto]

Check engine light as well as low tire pressure indicator came on, on the way home from the dealer, bought used as is. The message says Service Tire Pressure Maintenance System. I checked the tires and put them all to 40 as specified inside door panel and two tires do not read at all and the others read 42 and 38.

Any thoughts?

As well, can someone tell me how to read codes as well as reset them without taking it in or buying an expensive diagnostics tool? Will the codes generally come through the messages log?

On a good note, this truck is amazing!

Welcome, depending on the package you can read in the dash.. but, auto parts stores will read the codes for free!
