ok guys here it is,my 97 f150 4x4supercab has 3 main probs.airbag code reads (52)back up power supply,voltage boost fault. prob. 2, abs light 15 flashes and i have no idea what it stands for. prob 3,the temp gage instantly pins when power is on.
all fuses have been checked and read good.
anyone have any ideas to help me?
i also replaced the temp sending unit and checked to see if it has a good ground and it does

 

I have the airbag, Tire symbol and the brake light on at the same time right from startup. go figure, I was going to pull the bulbs but ya have to dismantle the whole truck just to get to the bulbs.. lol
BTW .. I get no codes..
