When you run a PCM or TCM update on a truck, does this have to be performed with the vehicle exhibiting no existing error messages on evic ? For example if your perform a PCM or TCM update on a truck that does not have TPMS sensors would it effect anything?
I ask this question since I had my truck taken in for routine work, they did a pcm and tcm update and for about a day and half my truck registered PSI on the evic for each wheel even though no tpms sensors were present.
Roll on 4 weeks later and I have tpms sensors fitted now but nothing still shows.
