This is the cable test from mine. Shows only one data line, which I think means that this is not obd2, and not can-bus. Just Mr. T's m-obd. Still works tho', can read data and set options.
Thanks for sharing uHu. Re-reading my FSM for the 1998 vehicle, mine is definitely Mr. T's M-OBD connector. I have read a bunch more about M-OBD, but still can't find a pinout for it for any market/year, let alone Australia/1998.
Mine has pins 4, 7, and 16 in common with you, just missing pin 5, which is probably the Signal Ground. Hopefully the Mini VCI can just use the Chassis Ground, probably pin 4, in place of the Signal Ground, and either use "K line of ISO 9141-2" or "ISO 14230-4" to communicate with the LX470.
Wilsil, as yours doesn't have pins 6, 7, 14, or 15, but has pins 2 and 10, it looks like yours may be set up to use " SAE-J1850 PWM", which the cable supports.
Strange that Toyota/Lexus should use so many different protocols, although it was before proper standarisation in OBD.
Also, maybe my 1998 LX is based on an EU spec vehicle (almost consistent with uHu), and your 2002 is based on a US spec vehicle, or maybe they are both hybrids.
Anyway . . . waiting for a cable to arrive.
