Bugger! SWMBO's new Yaris has the MIL lamp lit up. She says it came on on 
the way home from the dealer, but she ignored it, thinking it would go 
away! I'm not going to repeat what I said to that!

Anyway, does any kind soul know a method of reading the fault codes without 
a FCR, before we have to go traipsing back to Derby? I haven't driven it 
yet (apparently it drives OK), but the idle speed seems a little low. 
Sticky IAC valve, perhaps?

Follow up: I tried reading the fault code memory (you short pins 4 & 13 for 
anyone interested) but I got six different numbers and some of these could 
have been caused by me disconnecting sensors etc. So I disconnected the 
battery to clear the memory and took it for a quick thrash. No fault has 
flagged so far, so I hope it was just one of those things. If it happens 
again, I'll read the code before I start messing, then hopefully I'll be 
able to make sense of it.

Good plan. Its good practice to note any codes present on a car with the MIL
showing but no drivability problems, then clear them and re-drive it for
abit, and see which ones return (if at all)
