Welcome to the forum. I've not experienced this particular code, but there are numerous previous postings on this issue. A search of the forum finds this one:

Seach is your friend.

Doesn't look to serious, it may just be the first time the grid heaters have cycled this year or you may have a battery issue.

Couple of notes of better assistance on the forum.

1) You have a 4th generation truck, so you may get better responses in there (although this issue does seem common across years).

2) Punctuation and capitalization will make your post easier to read.

 

thnaks for the info did not know it was 4th gen. will try there and will check the batterys

 

A loose or poor Battery Ground Cable connection may cause this code to set. Clean and tighten battery connections first. Check the air heater circuit for loose connections also, connections at battery and relay are clean and tight.

 

thanks for info will do right now
