Fault Codes For Fleetwood Discovery With 06 Cat7

[jimbo@2006]

Hey Gang,

Anyone know how to get the fault codes on my 06 cat7 engine?

Tried the cruise control trick - key in on position engine off, cruise in off position, press set button until codes come on and nothing happened.

Reason I ask is I had check engine light come on while pulling a grade.

Thanks

Contact your chassis maker with your VIN. They can walk you through it.

If Freightliner: 800 385-4357 .

Assume you have checked the fuel filter(s), as this is where a clogged fuel filter will first exhibit symptoms. Also, check the air filter minder reading to make sure you don't have an intake restriction.
