08 Cascadia 60 series. Randomly all 3 check engine lights and the ABS light will come on for a couple seconds. The engine fan comes on, cruise turns off and the throttle is dead. I have to push the cruise button twice and then bump the brake and clutch pedal to get the cruise back. It does this while driving and at idle. When I start the truck when it's cold outside it will do it over and over in rapid succession until I can use the heater to warm up the truck so it seems to be temperature related. Some days while driving it won't do it at all and then suddenly it will do it over and over. Any ideas?
If your crankshaft sensor is two wire pull it out and clean it. Also clean the hole with a magnet and leave shim out if sensor doesn't hit reluctor wheel.
Did you ever get this issue sorted out? I had similar issues with my truck, also a 2008 Cascadia with a Series 60 and changing the engine wiring harness and all the sensors fixed it.
