I have an appointment at Pep Boys tomorrow to try and get more info on the problem, plan on speaking with the Jag service advisor Thursday, and if out of options I begin figuring it out myself.

Previously I had a cooling problem on my Ford pickup and a no-start condition with the Jag the professionals couldn't figure out and I had to do it. I'm a 30-year radio shop aircraft mechanic, have an associate degree in electronics, etc. No experience with these car communication protocols though.

 

Get hands on - DIY - with an elm327 as well.

 

I'm using the Torque Pro app with my ELM327 and Android phone. Is there now an affordable app for iPhone that will work with an ELM327?

 

Don I am sure this is a dumb question however do you have to have an active service on an Android phone to use Torque Pro?

These are the printouts the smog referee gave me, I don't understand them yet...

 

XJpurr,
I concur to reckon that the rejection of your car is very frustrating.
If I understand correctly, your car is correctly communicating with the proprietary Jag system at the dealership and not with the Calif smog referee testing machine, right?
If so, the problem should be sorted out between Jaguar and the Calif authorities who established the testing protocol. How could it be acceptable that such a protocol would be used that is not compatible with a car already licensed and on the market?

 

Yep that's where we are at right now.



That might be correct but we don't yet have enough data. The smog referee says there is something wrong with this particular car. The Jag service advisor says their machines show there is nothing wrong with the car. I am scheduled to have a check at Pep Boys tonight and may get the ELM device that has been recommended.


At this moment I know very little about a ELM device. Might need it if I ever get my wish of installing a proper V-12 in the XJ.

 

John,

I think the Bluetooth functionality of a mobile phone is independent of its telecommunications functionality, so I suspect it would work. You would have to be able to download and install the Torque or Torque Pro app, but I think that would be possible via the USB port since you wouldn't be able to do it via the Internet on an inactive phone.

If you try it, please let us know if it works.

Cheers,

Don

 

In about one minute the Pep Boys technician with his cheap pocket scanner on the "I/M" (Inspection/Maintenance) page found the readiness monitors reading "n/a" which happens when no car-to-scanner communication.

That exactly duplicates what the California smog referee found the readiness monitors reading "unsupported" due to no car-to-scanner communication.

The Jag technician with all his training and expensive equipment couldn't find this simple problem I will have to show Jaguar how to do it!!!

 

I think you've got the wrong end of the stick. Go back to Jag and ask which of the following two codes they found:

P1000

or

P1111


all Jags have one or the other, not both, not neither.

 

The readiness monitors are not reading on a pocket scanner or California state smog referee's machine. This seems pretty clear to be a car side problem and embarrassing for Jaguar their technicians with factory equipment can't find a problem that a Pep Boys employee can find with his cheap pocket scanner.

Mikey codes P1000 or P1111 where are they read, and do they relate to the readiness monitors reading blank?

 

Even the cheapest code reader will display P1000 and P1111.

P1000 means one or more monitors not ready.

P1111 means all monitors ready.

 

Starting to look like a very basic fault specific to the OP's car, like bad bit of wiring or blown fuse.

To DIY you basically need to check each signal at the "DLC" (OBD socket). Workshop manual says how but any auto elec guy ought to be competent. Ought...

 

I have an Innova 3130b scanner, a medium-priced unit when I bought it, and I have found that it does not always display the readiness monitors. Often it will simply report "No DTCs Present." I don't know why, but the same may be true of other generic OBDII scanners.

 

Maybe your reader is not cheap enough?

 

 

p1000 had my s type r checked a couple of mo. ago, no check engine light
would not clear p1000 used a new matco scanner turned out to be a transmission fault that the scanner could not clear (Jag dealer only) if p1000 show up it will not pass ca. dmv knows of the problems with these cars and will exempt them if you go to the referee, when I was checking a couple of mo. ago on my problem, yours came up on the internet. the thing is Ca. dmv now doing the blame game ( the old software vs. hardware issue) have them exempt your car until they can fix their problem. ( software or hardware/ Ca. DMV or Jag ) your just the end user!

 

P1000 is NOT a fault code. It does NOT relate to the trans. Please do not confuse this thread with such data.

 

Hi maywho,

I think you misunderstood the information you received. P1000 is a readiness monitor code that indicates an insufficient number of OBD diagnostic monitor drive cycles have been completed since the memory and any stored Diagnostic Trouble Codes (DTCs) were cleared. The drive cycle requirements vary from manufacturer to manufacturer and from model to model, but they generally involve getting the engine up to full operating temperature, driving at certain speeds, allowing the engine to fully cool, then repeating at least once.

As JagV8 stated, P1000 has no direct relation to transmission issues.

The other readiness monitor code is P1111, which indicates a sufficient number of OBD diagnostic monitor drive cycles have been completed since the memory/stored DTCs were last cleared.

Neither code indicates a fault, but P1000 tells an emissions tester that the system was cleared recently and it is possible that one or more previously-stored DTCs may recur. That is why P1000 is a fail in most places where emissions testing is mandatory. In order to pass, P1111 must be present so the tester knows that no recently-cleared DTCs have recurred.

Cheers,

Don

 

I found a California document listing many cars and trucks some with problems same as mine no communication with all readiness monitors. Most had a fix such as repair a ground wire or reflash computer, only a few had an actual exemption. I didn't see any Jags in the document, and it could be mine is a recent find and the document hasn't been updated yet.

Expected the smog referee to be an engineer or other very knowledgeable professional. But it looked like he had the same tools as a regular smog check station and little more knowledge than they did.

Spoke with Jag service advisor and after seeing pictures I e-mailed him of all readiness monitors reading "n/a" or "unsupported" he agreed there is a problem with the car and will take it back Monday. I recommended his tech contact a Jag engineer or whoever is the expert on this system for assistance. He said emissions warranty is 7 years 70k miles (California) so I'm way outside of that.
