Hi. I need to resurrect this thread because, after a month, the Stab Sys Traction Failed Service message re-appeared. If letting you know of these codes will help determine why the message re-appears, here they are: P0327, P0128, C0276, C0327. Can someone help in identifying what these codes mean and if any of these are directly related to the Stab Sys... message?

Many thanks for your kind response. This Stab Sys... message is really an annoyance.

 

I had an issue with crazy Stab Sys codes and it turned out to be my lines had air in them after I had brakes done. I don't know why...... Had it done at a shop, but once I bled the lines myself, codes went away.

It's a shot in the dark here....but that was my issue. I would say it's tied to the ABS system.

 

Once a mechanic said my torsion bar bushings need replacing, i told him to show me and it turned out he was talking about the lower control arm bushing (where the torsion bar ends)

Is your steering out of alignment btw? I read somewhere that if your steering angle is off by alot the truck will give a code.

 

p0327 Knock sensor (KS) 1, bank 1 -low input
p0128 etc or T-stat

Have your replaced the battery, bat connectors, checked bat pos/neg for solid connections?

I posted back awhile ago a p0128 was your t-stat/etc. did you not replace them?
