Re: Breakdown Information
Freightliner XC Chassis, Cummins 350 ISC Problems: Exhaust brake not working, coach surging at 66 - 70 mph. Diagnosis: Exhaust brake not recieving power signal from the instrument panel. Surging was caused by fuel distributor in fuel pump. The exhaust brake was diagnosed and fixed on the 2nd day. Fuel pump problem was suspected as the cause of the surging, but the Freightliner dealer was told to first diagnose the problem using Freighliner or Cummins software. It took 2 days to load the diagnostic software onto their laptop. Then Cummins took 2 more days to authorize the Freightliner dealer to work on the Cummins engine. Cummins would not ship the part until the authorization was complete (day 4). This was all due to a Cummins shop down the street. Cummins protects the turf of Cummins dealers. Freightliner could not expedite the process. Due to my Freightliner warranty, I could not go to Cummins first unless I was willing to cover the diagnostic costs in the event the surging problem was not a cummins problem. I was not told about the Cummins issue until day 4. My engine brake repair was a freightliner issue, not cummins. I got my coach back at 5:00 pm on day 5. Just in time to drive back home.422Views0likes0CommentsRe: Breakdown Information
RV particulars: 2003 Fleetwood Revolution 40C Driveline (Engine, Transmission): Cummins 350, Freightliner Chassis Miles:10500 Year:2003 Break Down Description:chassis suspension would not air up when jacks are retracted and engine on. Effect: chassis too low to drive, can cause damage to drive shaft. Cause: air dump valve would not reset Outcome:under the MH (front axle area) is an override button that will reset the system and allow the air suspension to fill up. Freightliner and Fleetwood still trying to isolate the problem. It could be related to the jack system or the dump switch on my control panel.574Views0likes0Comments
