Free training on Permanent DTC's , IUMPR , "fault isolation", running of monitors

Steve Instructor Irvine, California Posted   Latest  

I was asked at the last minute to put a class together. 

On Monday July 2nd at 6 pm I will be presenting a train the trainer on: OBD; IUMPR and how to use it to verify the OBD state of health; Permanent DTC's -- how to clear them using "fault isolation" data; how to run monitors faster, more accurately with high level of consistency. Some of the vehicles that we will be covering: Ford, GM, Chrysler,VW, Audi, Porsche, Jaguar, Land Rover, BMW, and Honda to name a few brands. 

We will be meeting at Gustafson Brother's Automotive training center in Huntington Beach.

Hi Steve yes if it wasn't that I am in Australia I would have loved to be there as well. I am probably about to show how diagnostically dumb I am by asking the question what is IUMPR?

You are correct

Isn’t that Mode$08? I would be interested in knowing how you go about clearing permanent DTC’s. I think you might mean running monitors to force a completion of a permanent code?

It is under Mode $09 for IUMPR. Yes you have to run the monitors and get a pass before the permanent code is erased.

James, the PDTC is not always associated with a monitor. Running monitors needlessly is something that we will be talking about. This is where "fault Isolation" comes in.

I have asked around within my little network of techs and this is the reply from one of them Hi Rod / Maurice I believe that the permanent DTC's are available in Mode $0A (10) ? Under EOBD (Euro 5+) I have read some info on the Euro IUPR (In-Use Performance Ratio), which is based on the US OBD IUMPR. Both are in essence are used to track how frequently monitors really run on the road. Data

Scott, You are spot-on in regards the material, yet it can be used for so much more. The so much more is what we will be covering. Mode $0A is the tenth mode, not mode $10. permanent DTC's are read in this service mode. Fault Isolation will help you clear the PDTC.

Hi Gil, This a very brief overview of the material. The level of intensity that we can go into will take 8+ hours. I am doing this class for a friend and have found when there are a number of techs attending the material flows better. Lets see how this one goes first.

Steve is this class similar to the smog update class?

Yes, for the base. But we will be getting into fault isolation and how to use the information to verify that fault is no longer present. The IUMPR will be covered in a little more details.

Shoot, I missed the cut off, the class is filled. I wanted to ask about IUMPR. I don't know what the numbers my generic scanner captured mean.

It means that the OBD system is in a good state of health. You are missing some data in your screen capture.

Danny, I read your chart as follows. Of the detected 14590 Key cycles, the system judged the driving profile conducive to fully testing the OBD system 7286 times. Of those 7286 times there was an opportunity to test the Catalyst Monitor 7281 times. The Catalyst monitor actually completed 8424 times. This is not unexpected as many catalyst monitors will actually run more than once per cycle if

Jim, Its a good overview. But there is much more than fun and we should care (if you are in a state that does emission testing) There are governing agencies that use the numbers for the vehicle's state of health. In the emission programs this information is golden. In California this will be used in part to judge repair longevity as well as state of health of the OBD system. This information
