I don't believe that your chassis ground is not securely attached...the problem is that the startermotor will pull "WELD" amperages to get the start goin'...this unfortunately is the ONLY place where the chassis ground gets to see the negative side of your battery...as time goes on...with every start this blue welding corrodes by re-welding again and again with each start....SO you've got to find a coarse wirebrush and undo the bolt wirebrush the ground to metal and remove the corrosion from the lug...in the process will reset the ECU and give reliable ground to the Brain of your system...delicate electronics that consume about 750 mA in the same current stream as the big hunkin' 300 or more WELD Amperage...providing a reliable ground? not likely....get that crap out of the main connection for a reliable ground to your ECU and not only will the codes vanish but will NOT be reappearing soon...best of luck on this....wear safety goggles~

unreliable ground puts "sand in the stew"...of course 99.9 percent of these gurus here are going to say "you're out of your mind"...but it's science...ain't nothin' else~
