I hope this help:
OBDII Wifi + Bluetooth (Torque, Android, Apple, etc) won't work with 1996 - 2000 Australian Prados.
1990 - 1996 Toyota (like the other manufactures) came up with their own ECM digital data stream called TDCL (Toyota Diagnostic Comm Link).
This transmits a few basic engine parameters at a snail's pace (taking 1 sec!).
1996 USA forced Toyota to be OBDII compliant. Toyota did, but only for USA models. The rest of the world Toyota continued with it's TDCL snails pace serial data protocol.
OBDI (TDCL) = 100baud = 1.25secs data refresh
OBDII = 10,400baud = 0.2secs data refresh
2006 Australia force Toyota to be OBDII compliant
M-OBD
BE WARNED! Toyota, if not forced into OBDII by the country will have used TDCL1 ... or for modern cars ... M-OBD.
WORSE ... Toyota wire up their MOBD to a OBDII socket. So it looks very hopeful to a the normal owner.
M-OBD = Multiplex OBD.
M-OBD can only be read by Toyota's Techstream or a handful of scantools.
Techstream can be DIY'd by $30 ebay/amazon "J2534" usb adapter
The giveaway is a metallic connector on Pin 7 of the "OBDII" socket, or the mention of "ISO 9141-2 protocol"
So an American 1996 4Runner / Tacoma / T100 / Colarado with a 5VZ-FE engine is OBDII.
It has a OBDII port (TDCL3) in the driver's footwell area, and the ECM Pin19 = "SDL"
So an Australian 1996 Prado with a 5VZ-FE engine is not OBDII.
It has a OBDI (TDCL1) "Diagnostic" port in it's engine bay and requires counting the CEL.
The ECM Pin19 = "VF1" serial data stream if TE2 is shorted = SNAIL's PACE LIMITED DATA
5VZ - Australia (OBDI) Pin19=VF
5VZ - USA (OBDII) Pin19 = SDL
To Manually read OBDI (TDCL1) Fault Codes see this excellent post:

It is possible to digitally read
- OBDI (TDCL1) fault codes.
- OBDI (TDCL1) Serial Data.
You can
- buy a v expensive 3rd party scantool (OBDI compliant)
for $360aud DTDauto's ScanTool http://dtdauto.com/Product/Product_d...I%20Scan_E.htm
like this PradoPoint member did: http://www.pradopoint.com/showthread...or-1998-5VZ-FE
- use Toyota's Techstream
a) get a "22pin to 16pin" adapter ($15 ebay/amazon)
b) connect that to a "J2534" or "Techstream USB" adapter ($30 ebay/amazon)
c) connect into a computer or grounded laptop running Toyota's Techstream
- DIY your own OBDI cable + use free software
for $8 see here: http://www.mr2oc.com/showthread.php?t=520850

As you can tell ... I have a 1996 Prado 5VZ-FE. I recently changed the head gaskets and now wish to accurately monitor Coolant Temp (+ other parameters).
I may
- ebay USB techstream cables
- DIY the $8 OBDI USB reader
- DIY custom OBDI reader using Arduino and transmit via bluetooth to an arduino in the cabin with a LCD to output.
- DIY custom ECM wire splice reader in the cabin read via an ardunio and display on an LCD.
But I now know I can't just hook up to ECM Pin 19 and get a nice OBDII stream = (
Hope this helps
