Hello guys, long time lurker first time posting here. I have a 2005 Freightliner Classic w/14L Detroit 60 Series, 10 spd Ultrashift. I get a "No Data Link" alert after the truck is washed even when the hood is kept closed. When I get the alert the Tach, speedo, oil press, coolant temp, and voltage gages all are dead. After sitting 20 minutes or so it all goes back to normal. Fortunately when this happens it still starts and shifts. I have glanced over the connectors and harness and sure don't see anything that would indicate an issue.
I had the dealer look at it and they say they can't find anything wrong, they claim the weather packing on the harness and connectors look good and there are no fault codes stored in memory. I know sooner or later I will run into a rain and not sure what will happen... If any of you Freightliner owners have experienced this or have any good ideas on where to concentrate I would appreciate it.
Thanks,
DMK
