I believe this link will provides codes for a OBD reader ref the TPMS problems.

Perhaps someone can verify.

Looks like my problem relates to a "CAN signal missing". I am not sure what this might mean.

Perhaps someone can advise.

jaghelp.com: Jaguar XK TPMS DTCs

What exact code # are you reading?

The Jaguar Shop Manual which I have states the following:

CAN signals missing ......On vehicles from 2007.25MY - Warning indicator flashes for 72 seconds and is then permanently illuminated. 'TYRE PRESSURE SYSTEM FAULT' message displayed.

My problem relates to the text above highlighted in bold.

I have no way to determine codeing. I am trying to find a DIY fix to eliminate the problem.

I have the same manual.

That message can have many causes, such as "No transmission from more than one tyre pressure sensor or more than one tyre pressure sensor fault" or just a generalized "TPMS fault" also according to that manual.

You really need the Jag diagnostic equipment to narrow it down without just throwing parts at it.

The 'CAN signal missing', if that was the cause, would just mean that the TPMS module behind the fusebox between the rear seats cannot communicate over the internal data link (the CAN bus), which is unlikely especially if everything else in the car is working.

I think it is far more likely there are problems with the wireless part of the system, such as the sensors in the tires, the antennas or the receiver.

Been here, done that. Take out your right headlight and see if the wire is improperly routed. This drove me crazy. Hope it helps.

My intermittent TPMS problem occured only after I had a new set installed with a new set of custom made wheels.

Richard,
Have you put the Selena wheels back on yet, as I suggested in the other thread? If you did and, after driving at least 10 miles, you didn't get the TPMS warning, you know there's a bad sensor in one or more of the Braelin wheels.
Stuart

There are no tires on the Selena wheels so it would be hard to do. I have to take the Jag to Discount Tires to see which one if any TPMS is not sending the signal to the TPMS reader device.

I think you could be correct. I do know I have the correct frequency TPMS installed on the Braelins.

Richard,

Tires are so yesterday!

It didn't make me laugh, but it made me smile.
