I know some people often ask where they can get the fault codes from so here they are for 3CT and 3CTE models respectively.
If we are really lucky some nice Administrator will pin this post for you!

With the Ignition off bridge the E1 and TE1 with a piece of wire on the diagnostic socket under passenger seat. Turn Ignition to on position but, do not start engine.

Count the flash codes from the lamp on the dash i.e. 1 flash pause 4 flashes would be code 14

Excellent stuff, will definitely come in handy. Took us a bit of scouring the internet when we were hunting for codes to diagnose Nick's bus

The fault codes can be cleared by diconnecting the battery for 5 mins or so, I left mine disconnected for 20 mins and it did the job. Thanks to yamp for the info. Archi-K

Motor And Diagnosis has a pic of where to jam the paperclip to read the codes, might take a bit of hunting around but it's in there somewhere.
Doesn't seem to be working just now, my IE is broken and it won't behave for me in firefox:doh:

Hello everyone, This is my first post on this forum, I bought my first of these amazing cars of a popular auction website for £560 last week - it is the Lucida X Luxury 2.4 petrol - 2TZ-FE engine and I was wondering if anyone knew the fault codes for this engine? Thanks in advance.

Hi i have just done this test and found that i have turbo trouble pressure to high or to low :emot-giggle: ... This is on the engine management lamp. Whilst i was doing this i noticed the oil lamp was also giving code as well anyone know where to find the meaning of these codes?

Yeah, oil codes would be useful, i got rid of the fault with the speedo, but the oil light code was still flashing away
