I have a Toyota Harrier (98) but unfortunately my local Lexus dealer cannot read the fault codes on his OBD II reader as only set up for UK vehicles,also tried an independent garage with same outcome.I am intending to buy a universal reader on ebay and just wondering if anyone has bought one or know where to get one that will work.I have the fault codes list just need to find a reader to tell me what the they are on my vehicle as have an intermittent transmission fault.Any help much appreciated.

I bought one of the ELM327's for my Aristo and that never worked on my JDM Aristo, so not sure you'd have much look as that uses something else which isn't compatible, even though it had the OBD-II port it uses a different protocol.

What engine is in that Harrier? Is it the 2JZ-GE? Just wondering as there's a trick you can do on mine with a paperclip shorting two pins in the diagnostic port in the engine bay that causes the fault codes to get flashed up onto the dash so you can see them.

If it is the 2JZ probably worth giving this a go if there's the port in the engine bay:

No JDM models use OBDII until at least '02 onwards. Instead they have a diagnostics port in the engine bay, you bridge a couple of terminals together & it flashes codes via the engine check light in the instrument cluster. A google search will give you all the relevant info you need to do this.
