Good on both fronts @JohnGarziglia (see below):I would start with asking does your VMS display tire pressures, and does your OVMS likewise display tire pressures.

However, I haven't tested for continuity as I don't own a multimeter. Guess it's time to get a new toy for the toolbox Any recommendations? I've been looking at Fluke but there are so many!
Here is the order I found had to do it in, not following completely the above but maybe misunderstanding it somewhat.The new TPMS subsystem in OVMS works off the concept of 'tyre sets'. You can read into a set with:
tpms read summer
(for a set called 'summer'). If you don't specify the set name, 'tpms read' will simply show you the IDs (and not save them in a set).
You can also manually define sets with
tpms write winter 11111111 22222222 33333333 44444444
You'll need to drop by a garage with a TPMS tool to get the values for those IDs.
The order of IDs is vehicle dependent. For Tesla Roadster 2.x it is FL, FR, RL, RR.
You can write back IDs with:
tpms write winter
(for a set called 'winter').
The 'tpms list' command will show you what sets you have defined.

You have an OVMS v3.2 module (or v3.1 module labelled on board as July 2018 or later), or have made the jump-wire modification. 2018.03.05 build and jump-wire done. However, I haven't tested for continuity as I don't own a multimeter. Guess it's time to get a new toy for the toolbox Any recommendations? I've been looking at Fluke but there are so many!
@markwj FastTech says "Discontinued" is that just how they say "Out of Stock / Backordered" or is it being modified?
Picked up a multimeter (a Fluke 101) and tested across the correct pins and got continuity then checked adjacent pins on both sides and confirmed no continuity so it seems the jumper is fine.Important, do not only check for continuity on the two noted pins, but also check to confirm that there is NO continuity on any of the adjacent pins. It is just as easy to have solder overflow on small pins like this wire needed to be connected to, as it is to have a bad solder joint.
@markwj / @JohnGarziglia / @Nvbob would love your thoughts on this thx ^^So what else is left to check? Could it be that my TPMS was upgraded from the Baolong system? Is there a way to check without dismounting the tire?

I disassembled everything, reassembled it and restarted the module. Ran the commands shown below and you can see the results: "tpms read" still throwing the same error msg
I can't believe that I've been away from this forum for so long. Fortunately, I heard about this TPMS upgrade on the OVMS mailing list. I'm looking at the "Discontinued" status on FastTech and have registered my email address for an update when they're available again.
I'm been looking forward to a summer+winter TPMS system like this for ages, and almost started on a solution myself. I'm much happier that Mark got it working!
I'm still curious about this as well. Thoughts?Out of curiosity, does "tpms status" read from the new TPMS module or is that simply a straight read from the CAN bus?
