Help Request Posted
2005 Saab 9-3 Arc 2.0L MIL Lamp on VIN: YS3FD79Y35
P1682: plausibility fault between voltage feed from 15 and main relay. Not sure what the description is saying. Do we have a problem with power from ignition ( 15) to the main relay? Or loss of power from the main relay. Cannot find much info on this code, has anyone else had any experience with this code? Thanks for any help...
