Whats Best Diagnostic Tool For 2003 Lexus ?

[Jock666]

2003 Lexus GS300 - what is the best (factory standard) diagnostic tool or software for the older model cars? The old Mastertech machines are thin on the ground and no updates avail since 2007 so not an option. Is it then onlt TIS thats avail??? We have numerous other high cost machines (£3000+) here that are generic OBD but need something Toyota specific for the older model.

The official software is always Techstream...

Autel do nice units. I have two. Doesn't do the 95 LS400 but should do the later ones no bother. Includes live data and should support all the Lexus specific systems.
