I see that the latest update of the SZ viewer app now has a TPMS tab. I must plug it in and see what it does.

Looking at the Circuit diagrams, for the UK it appears to be

Pin 1 - (Grey) - +12Volts
Pin 3 - (White) - CAN
Pin 11 - (Blue) - CAN
Pin 12 - (Black) - Ground
Pin 13 - (Black) - Ground

Now those of you familiar with OBD2 wiring will be intrigued by the numbers as they should be

Pin 16 - 12v
Pin 6 - CAN
Pin 14 - CAN
Pin 4 - Ground
Pin 5 - Ground.

However if you count the pins backwards then the numbers match so I think either Suzuki or the OBD2 specification looks at the reverse of the connector.

This is the OBD2 connector on my Gen3 from 2011, no CAN bus on this variant.

The dongles/obd reader I have has the pin numbers marked on treating face, but they don’t seem to be on the socket (attached to the car) so PIN numbers must be from the plug end.

Did you ever figure this out?
I'm interested in the Autool or similar.
