Default Help with codes

Ok guys, on startup, I get the following messages:

"Service Traction System"
"Service ABS"
"Service Active Handling"

A check of the codes reveals this:

28-TCS C1214 H C - "Sol Valve relay contact or coil ckt open"

99-HVAC B0338 H C - "Inside Air temp sensor open"

For the love of GOD, what's it all mean???!!!

Yes, I reset them, and they both came back. The other post is what prompted this one, since it doesn't cover that particular code for the TCS... I'm getting the same messages, just a different code...

Do you know if "open" means the circuit is open, i.e. not functioning?

Thanks!
Vaughn

I went and looked in my service manual...it describes the problem as an "open or short to ground" possible corrosion etc...loose connection with the module...

Thanks, I'll see if I can find a loose connection... Maybe when I put the aluminum gauge trim rings in, I didn't fully seat the button, and it took a little while to work loose...

Cheers,
Vaughn

can't speek to the codes but in electrical talk OPEN means that there is no electrial connection to the device that the computer can find. Or in other words there is a short to ground preventing the conneciton or the wire that it wants to use is not connected " open " hope this helps.
