Good afternoon ladies and gents, hope all are having a great Easter weekend.
Wondering if anybody can give me a clue as to what the most common cause of the "wrench light" illuminating is?
Here's some back ground:
I've been traveling out of town the past few months, 500 miles round trip about every other week. Having had the truck completely gone through a few years ago by Domestic Diesel, them addressing all the minor and major issues plaguing the 6.0 platform this truck has been a beast to say the least, not an issue in nearly 30,000 miles since the repairs with total mileage on the truck being 88,000. Let me be clear, I am not relating this current wrench light issue with the work done at Domestic Diesel, I could not be happier with everything they have done for me and my truck, if it weren't for John and his guy's I'd have sold this truck long ago. I could not recommend them more nor could I put into words eloquently enough to do them justice, Johns shop is clean, the knowledge and professionalism oozes from the walls and although I haven't once been in his shop that it wasn't crazy busy John and his guys make you feel like you're their only customer.
For about 6 months now I've been noticing a nice blast of coked up black exhaust smoke each time I get on the accelerator hard to blow out the turbo but am thinking that is a normal thing, could be wrong, IDK? Yesterday afternoon on my way back from Fresno about half way into the 240 mile trip I noticed the wrench light had illuminated, it was just as I was approaching the California Grape Vine, a relatively steep ascent over about a 7-10 mile stretch of highway. I was running light having left the majority of my equipment on the job, the truck was running completely normal as I traversed the Grape Vine at 75mph without as much as a hiccup, all temps normal, nothing out of the ordinary besides the wrench light being illuminated, the truck ran perfect all the way home. Upon pulling into the driveway and idling the truck for about 5 minutes to cool down I shut down the engine, restarted it and the wrench light was off so not sure if it was just a fluke or if I have something to be concerned about? I hooked up my programmer this morning and there are no DTC's, the wrench light is off and the truck starts perfectly.
If Domestic Diesel was open weekends it would have been up there first thing this morning unfortunately they are closed on weekends so I have came to the second best place for information regarding Power Strokes, it's amazing the knowledge here and the help others are more than willing to provide when things go wrong!
This truck is needing to be used to head back to Fresno on Monday morning, I am not comfortable in doing so without addressing this issue, if it in fact is an issue and not just some fluke in the electronics.
Thanks for reading and any help I will no doubt receive!
