You don't really need any fancy equipment to read codes on pre OBD Toyotas!. It can be done using a system of blink codes. First of all find the diagnostic socket in the engine bay - it's a small rectangular box with a hinged lid. Use a piece of wire to bridge across terminals TE1 and E. With the ignition switched on - you'll see a flashing lamp in the instrument display - it's signalling fault codes in terms of blinks. Code 42 for example will be four blinks - short delay - two blinks. Then there will be a longer delay and then any other fault codes will blink. When all blink codes have been displayed the system will cycle back to the beginning. Remove the wire bridge before starting the engine.

Mine is a 2002 model but my reader says Linking Error. Does this advice work?
