Hello,
I have searched this forum with not much luck. I have a 2004.5 Cummins that wont pass smog due to an incomplete module when hooked up to the OBD. No check engine lights and truck runs perfect as always. A while ago the wipers went goofy and replace the multi function switch and windshield wipe motor. Seems like everyone is saying keep driving it which could take a thousand mils or more? Anyone experience this or know of a fix.

TIA.

Which module is not ready for the smog test? I had an issue with O2 sensor and the CAT monitor test.

 

That's one of the problems is "they" can't tell me which module it is and I guess my truck doesn't have many of them?. I guess I'll have to pull a code if there is one and figure it out.
Thanks for the reply.

 

I didn't have any codes at all... Received the same advice which was to drive and wait for it to be ready. Never happened. How many 02 sensors does yours have?

 

I'll have to search to see how many o2 sensors there are and where they're located. UGH.

 

This happened to me with my BSN '15 3500. Was told to drive it more, I did. Very long story short, the shop I took it to found the O2 heater wasn't 'ready', when I took it back an older gent said my truck doesn't have an O2 heater. Passed smog.

Try another shop.
Back to morning brew . . .

 

Yeah, not sure what to do. I've searched for an 02 sensor for my truck and it only pulls up gas engines.
