I do have a service manual for this vehicle. I will put the offer up for you on the cost of it.

How are you pulling the codes on the unit?

191 is output shaft speed sensor code

524 is there is a J1939 information missing. That is becuase there is a sensor not sending the right sognal. It can be any of them or related to the codes you have.

2900 is Accelerator Pedal sensor Signal out of range

3719 Regen needed. Soot level high

3351 DPF filter worn and needs replaced.

I am using Detroit diesel diag 8. I feel the the service I already paying the site for should cover the info, and I should not have to pay more for it. can you please send more info on the faults I listed.
Expert:  Jeremy replied 1 year ago.

I'm going to opt out. I have to pay for the manual to get you the manual.

You can go to the dealer and pay 4 times the amount for the same manual.

i don;t work for the site. I pay for this out of my pocket to provide to you and at the cost, I will be in the hole.

Good luck to you and your repair.
