This Car Wont Run The Ccm Monitor. Flagging The Evap System On Mode 6 Data With Autoingenuaty. No Codes With Any Other Scanners. We've Tested Evap Sytem And Found No Leaks Checke All The Evap Components And Fuel Tank Pressure Sensor

This car wont run the CCM monitor. We can get it to run all other monitors including the EVAP system. It has flagged the EVAP system in mode 6 data. We've tested every component on the EVAP system and also have replaced the purge solenoid. The fuel pressure sensor is working, and the smoke machine will drop to 0 in of h20.

Hi Gene. I"m not sure about your EVAP problem. We have a customer with a similar Jaguar that also will not set the CCM to complete. The BAR OIS system does not check CCM so you can perform an emissions test without the CCM complete. Check out page 6 of the Smog Check OBD Reference guide (footnote 2 at the bottom of the…

Agree with ya. I’ve seen them go through not ran. Hopefully that’s what you're trying to accomplish.

Yes this particular car was here for a smog and it would not pass with the CCM not complete.

Hi Mike: That's an interesting document. When did someone change the definition of "Continuous Monitor"? I'm very surprised that CARB and the EPA don't have an issue with this. It's not like Chrysler running the Cat monitor before the O2 monitor. Continuous means continuous. Or, at least, it should! Guido

Actually, the definition of CM has not changed per regulation. CARB does have an issue with this. That's why this document has been posted at the OBD Clearinghouse -obdclearinghouse​.​com OEMs are (encouraged/required) to post any anomalous behaviors that may affect I/M at the clearinghouse. I hope this helps. -Bob

Hi Bob: You're right, of course. I didn't think to look there. I took a quick look at CARB's Smog Check OBD Reference (testing anomaly list). Funny thing, they don't list any issues with Jaguar (or Land Rover for that matter). Granted, the list hasn't been updated since 2016 but one would suspect it should be in there. Guido

You peeked my interest.:) What exactly do you mean by all that? - Bob addressed the CCM for this model and I strongly advise people to use the clearinghouse web site for OBD issues but you said "Continuous means continuous". Care to explain what you mean? - Continuous does not mean all the CCMs run all the time. - Non-continuous does not mean the monitor runs once per cycle. - Cat before…

Hi Randy: Peeked, peaked, picked or piqued? I'll be happy to explain them to you while you're gracing the mahogany. ;) 1-1: My understanding is that after the Diagnostic Executive authorizes the monitor to run, a Continuous Monitor runs from Key On to Key Off unless suspended (e.g. Misfire Monitor suspended for low fuel level, etc. or blocked due to a code in another system which is required…

Haha, good catch! I will choose picked for $200. :) You picked my interest. I will assume everyone here knows the difference between a monitor and a readiness flag. If you don't, this won't make much sense. 1) Continuous v. non-continuous. Simply put, the difference is that a continuous monitor can run again, during the same drive cycle, after a decision has been made. A non-continuous…

I'm not sure that Randy's first sentence is a given. It was actually difficult for me to discern from the OP whether or not they are trying to set readiness, or to get a particular CCM to run, since many folks do get these confused. If it is getting a particular CCM to run, then all of the advice here is spot on. If it is just to set readiness, we have a different story. It has always been an…

Yes the dealer had performed this recall and has a sticker for it under the hood.

Well after endless hours we continued to drive the drive cycles for evap and after the second time the ccm monitor completed after 30 minutes of idle. All of this started to happened after we reprogrammed the PCM with the latest calibration. We found that the CCM monitor would only complete after it passed the .020 evap leak. Originally the car had come to us with the 02 monitor not running and…
