OBD1/OBDll
 

How many people here have an X that is OBDl or OBDll compliant. Just wondering as I scanned my wifes car for a problem this past weekend, and for the hell of it decided to scan my X, it shows up as OBDl using the Torque app. Also the emissions sticker under the hood does not say that it's OBDll compliant

I have a obd2 compliant model.
All California models and Canadian models are OBD2 from what I have read.
Main differences are they have EGR and an oxygen sensor after the CAT.
There is also better monitoring of misfires for each cylinder.
I am sure there is more.
I also use Torque pro

Mine doesn't have a EGR or after cat 02.

It monitors misfires good had a coil go out, and within a city block the CEL came on, plugged it in, gave me the cylinder # that was bad.

Were you using the Torque app or a scanner, if a scanner what type?

All vehicles built after 1996 with the exception of a few 1995 models are OBDII. Federal requirement.

Scanner. Just a cheap one from Walmart.

wrong.

The gvwr excluded the Excursion.

But, u must remember, they use the same plug under the dash as the OBDII vehicles.. So, alot of times they are called OBDII

Depends on what engine is in the Ex.

There's no California model for the PSD's.

I used to think the same thing, until my esteemed colleague Crazy Tom explained that isn't true, as the above post has shown you.

IIRC, the V10 forum has a lot of info regarding this topic.

They use OBD II hardware and communications, but they're "brain-damaged" back to only OBD I calibrations in software.

Look at the emissions sticker under the hood. If' it specifically states "Califonia" and/or "OBD II", then that is what it is. It it states neither of the above, it's a "Federal" with OBD I software.

Would you mind going and checking the label? If it's OBD I, it takes an extremely severe misfire to set a fault code. Mild misfires seem to go unreported by the misfire monitor.

OBDII was mandated by the federal govt for all 1996 model year cars and trucks. No vehicle was exempt. This standardized the ALDL connection so all were the same and it also mandated the connection was to be placed inside the vehicle in or around the dash. However, some like VW, like to hide it behind the ashtray. OBDII standardized the codes. All vehicles use the same numbers for the same general things. Misfires and the like. However, most manufactures have vehicle specific codes for their systems because of special functions. That is why 1 tool will diagnose every vehicle with a CEL on. Cheaper tools will give a code but it may not tell you the part or system that is causing the CEL. All vehicles will give a data stream for ease of diagnosing a CEL. Not every scan tool will give all information regarding a data stream because of the software. A $100 scan tool can't do the same as a $1000 scan tool. They will both tell you why the light is on but the $1000 tool will tell you more information and do more for you. It's all in the software. Why do you think OBDI in the Ford line was a pain through the 1980's into the 90's. Hard to diagnose problems. Very little information was given. Data stream was terrible. GM did a fantastic job. A lot of information was given. Data streams gave a lot real time sensor readings. That is the difference between the 2. Nobody has OBDI after 1996.

I guess you ignored what was said above.
The excursion sold in the US (except Cali models) are not obdII compliant.

That is not correct.

I was under the same impression, and when the guys here let me know I was wrong, I looked at the info they posted for my benefit, then corroborated the facts with my own research.

Please don't stubbornly stand by your statement when several of us have informed you of the exception to the OBD II requirement. Please do some research and you will find the same info.

Like I said earlier, the V10 forum covers this topic extensively:
