Dear forum,
My car (2010 XJL) shows 'TYRE PRESSURE SYSTEM FAULT' on dashboard. All pressure-sensor checked separately - all work. All initiator ( antenna ) checked - all work. Receiver has checked - works. Wiring checked - everything OK (no cut or short). All connector/contact checked (receiver, initiators, CentralJunctionBox - where the "brain" , CPU is).
I have DDS so computer check shows C1D21 : "General failure information - system programming failure"
I would appreciate any suggestion.
Unfortunately there is no dealership in my area so taking the car into one is not an option now.
Thanks and waiting for your replays...

 

How old are the sensors, and when you checked them was their battery charge also indicated? Their
lifetime is 5 to 10 years, thus if they are original your problem could come from low batteries.

Hi Thierry, Sensors are 3 y-old. TPMS service guy checked with handheld device: prompt respond and correct Jag code received from all 4. He told this immediate answer shows battery is OK.

 

Well, that was an usual suspect worth checking... Are they original Jaguar TPMS sensors or third party? if non original there can be issues.

 

Dear Thierry, Thx for your update. 3 sensors are original FoMoCo Jaguar/LandRover sensors. One is a T-Pro Hybrid HTS-3000.
From the 3 FoMoCo sensors 2 are TG1B (as the originals with all X351 from 2010), but the 3rd one is a V5 type TG1C (? newer one for newer Jags? ) - and I think this V5 is the problem.
In the new year I will replace all with TG1B - so all will be in the same series...

 

Well, all X351, from 10/2009 got from factory TG1C... https://www.vdo.fr/media/746526/2019...ation-list.pdf
as there is absolutely no international norm for TPMS, and thus no obligation nor even info on compatibility, I'd go for these, not for TG1B...

 

Hi, I have no idea why VDO's table shows TG1C but I still have the original 4 sensors come with the car and had been replaced 3 years ago. Are TG1B for sure.
I will check it up at the tyre shop with the mechanic (who checked transmission of the sensors last time... )

 

Hi, Finally problem solved:
I mailed several friends and partners with my problem and from a wheel-exporter I have received a box of sensors.
Now in my XJ all 4 are original JLR / FoMoCo and system runs correctly ( auto-recognition works... as it should )

As I have more sensors than I need I can sell the rest... If there is interest...
New sensors, never used in vehicle.
Removed from new JLR wheels because wheels were exported to Europe (the frequency is 433MHz in Europe).
Both TGB1B and TGB1C sets are for sale: US standard 315MHz. AH521A159CA, 6G921A159AB, 4H231A159CB and BH521A159CA
Mail me if you are interested in...

 

Hi,
I still have some sets of original Jag TPMS sensors (315MHz).
