Hey guys currently have a k1b1l18U in the shop for error meter communication problem 558 code on the dash. My tech has check all resistance from meter and is ok. We have swapped dash screens over from a known good unit and put the bad screen onto known good unit. Problem still persists on bad unit even with a good screen but does not transfer to good unit from "bad screen" that is displaying the error code.
Ive seen people ask this question but nobody has actually offered a decent answer.
Just wondering if anyone has figured it out yet. Cheers.
