In addition running a system check with the scanner I am getting 5 "not ok" messages like:
Mid: $03 TId:$d4
02 bank 1 sensor3
Min 32.768 max 40
Do those help at all, worth posting?
When you're getting multiple codes, the first thing you need to do is reset themdrive the vehicle and right after you get the dash warning(s) pull over and run the scan again. Then, compare the second readout with the first. If some codes have dropped off, that is an indicator that the dropped codes were generated after the code you get the second time. It is common for multiple codes to trigger after the initial trouble codethe first time.
Then, if you post that code, we can do a look up. Some on here are pretty good with finding MB trouble codes. Good luck.
