Computer codes

[Ckbarger2]

My coach is setting codes that state the particulate filter needs to be cleaned. Took it to Cummings repair and they said the filter is fine. They think it is in the chassis harness and it is causing the computer to set bad codes. The coach is in a line mode and will only excel in Econ mode but very slowly. They stated the harness needs to be changed. Trouble with that they don,t make them anymore. Seems to me that there should be someone out there that can ring out the harness and troubleshoot the problem. When we purchased the coach the transfer switch burned up. The seller had someone replace it. Do not know if that could have caused the problem.

transfer switch is involved in switching shore power and generator

unless some DC chassis wiring is run thru the same compartment and was damaged by fire/heat

then NO.. the TS has nothing to do with your bad engine codes

It should be repairable but with what they get per hour a delete kit my be more cost effective.
Give us some more info.
