Hi
My red warning light is on. It goes off intermittently but most on. I'm getting a fault code 91. FM=2
Any ideas what the code means. I can't find it online.
Thanks
Rick

I went to cummins today and said I had codes from earlier in the week on my throttle control.
What happened was everything g was fine. My warning light started to go on and off and I got that code. As time went on the warning light stayed on longer. I got the same code.
On Friday my exhaust pipe after the exhaust brake fell off. I had it repaired Monday and no more warning lights or codes. Looks like my exhaust was heating up the engine compartment causing me to get codes. Now that it's fixed everything is fine. Cummins couldn't find anything wrong. So I'm back on the road on my 8 month trip.
