Service Engine Soon Light
On our way home from Moab last week the “service engine soon” light came on and the van started to shut off occasionally, but it always restarted.
I just purchased a Scanguage II but it indicates there are no codes stored and no codes pending and the Scanguage will not reset the light. Has anyone else had this experience? I set up the Scanguage per the owner’s manual, is there something else I need to set up to be able to read the codes?
I don’t think its bad diesel fuel because we have gone through more than one tank since it started. I drained the water off the fuel with no improvement. I cleaned the battery terminals and checked that they were fully charged. Before we left Moab I purchased a spare cam shaft position switch but I have not installed it yet. Any other suggestions would be greatly appreciated.
