Has anyone found a cost affective OBD reader for the Jimny Fourth Generation, JB74, 2019 ?
If so which one is it.

I have tried using the ELM327 without any success. Some background information.
Looking at the connector
Pin 1 – Blank
Pin 2 – Blank
Pin 3 – Blank
Pin 4 – Black Wire - Chassis GND
Pin 5 – Black Wire - Signal GND
Pin 6 – Blue Wire – CAN High J-2284
Pin 7 – Blank
Pin 8 – Blank
Pin 9 – Blank
Pin 10 – Blank
Pin 11 – Blank
Pin 12 – Blank
Pin 13 – Blank
Pin 14 – White – CAN Low J-2284
Pin 15 – Blue – ISO 9141-2 L-Line (ISO 9141-2 and ISO/DIS 14230-4)
Pin 16 - +12 v – Battery Power

The above descriptions are based on
pinoutguide.com/CarElectronics/suzuki_ob...gnostic_pinout.shtml

It appears the Jimny uses the J-2284 Protocol
However, from my attempts the ELM327 Blue Tooth adaptor does not support the J-2284 Protocol.

I use a cheap ELM327 Bluetooth reader from ebay together with this app on playstore - malykh.blogspot.com/2014/02/sz-viewer.html?m=1

Works for me, but then I don't really know what I'm looking at.

Thank you for your reply. I tried the same application you used “SZ Viewer a1” but it does not like my ELM327. I have the one in the following link. What ELM327 did you use?

I miss remembered, it was actually from amazon
ELM327 Wifi OBDII Scanner,Gemwon... www.amazon.co.uk/dp/B0721DC46Y?ref=ppx_pop_mob_ap_share

I did have a problem with one update of the app but the developer fixed it when I reported it so make sure you have the latest version. I haven't tried it for a few months though.
