Re:JB74 OBD2 connection

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.

By coincidence I was playing with code reading today

Did you ever figure this out?
I'm interested in the Autool or similar.
HK version Jimny here!

Unfortunatly not, I'm still very interested in finding a solution though!

OK so I did some work on this.
I started with Martin's pin-out:
Pin 16 - 12v
Pin 6 - CAN
Pin 14 - CAN
Pin 4 - Ground
Pin 5 - Ground.

Which led to me this site , where it looks like that pin-out is used by ISO 15765-4/SAE J2480 (CAN) protocol.    
That may or may not be accurate, but I decided to set off and look for an OBD2 unit that is capable of that protocol.

I couldn't find anything on the Autool X60 that indicated it was compatible with the ISO 15765-4 protocol.  But I did find this unit , at twice the price of the Autool which specifies that protocol.

I ordered, plugged in and it worked straight off the bat.  Note:  I have a JB74W in Hong Kong.

I do like having a digital speedo for my aging eyes!  No idea why Suzuki missed that out of the dashboard display.

Excellent work Twisticles!!  I'll be ordering one of those.

I wonder if the Torque Pro app is not compatible with ISO 15765-4 either?

Sorry no idea about the Torque Pro, I dont have a reader.

Also, I bought one of these too , which is just a digital display reflected up to the windscreen.  I didnt use the included plastic that you're supposed to stick where it reflects, so I get a bit of ghosting where it reflects on both the inside and outside surfaces of the windscreen.  But I can live with that to have the speed so clearly in my peripheral vision.
Great little gadget for $12! 

Do you have a photo of the other unit in place?

I run torque pro on a Android tablet.
Australian Jimny so no idea if they are different.

crash486 JB74W

TorquePro with a Veepeak b/tooth connected fine on JB74W, looking for a battery voltage meter PID as it is not indicating?
