Hello all,
I have gone and bought a Yaris - came recommended by a work friend.
Filled it up with petrol and drove home, about 50miles, but as we got on the motorway the dreaded engine malfunction indicator light (MIL) came on.
I have had a search of the internet to find possible solutions but appear to be useless without a reader of some kind. One thing I did find was the fuel cap had not been tightened - tightened it but am unsure whether the fault should clear on its own.
Could anybody advise on how to reset this, thought of disconnecting battery but thought there could be an easier way like holding left ear whilst humming the dambusters tune.
Apart from taking the vehicle to dealers could anybody also recommend a fault code reader for my vehicle and so I could find the actual fault causing the MIL to come on. A further question is where the socket is that any possible fault code reading device would be plugged.
Thank-you in advance

Car Mechanics did an article on Yaris Engine Electronics. Have a look at their website to see if you can buy the article (or email them).
I'll look for it .. but not just now (insomnia)

The MIL would certainly illuminate if the filler cap was loose as the system sees the fuel tank not sealed and therefore allowing fumes to escape uncontrolled into the atmosphere rather than controlled venting into the inlet manifold. Depending on the software if this was the case then after a set number of driving cycles the light may go off but the fault will be left in the memory as an historical fault. The diagnostic system is EOBD11 and its possible to buy a basic reader to read and extinguish codes for not much money but that is all it will do. The diagnostic socket will be within reach of the drivers seat (by law) so look aroung the underside of the dash and in the cubby holes for a sixteen pin trapezoid male connector (sometimes purple). I will check on my laptop for a specific location later and post its position.

A friend has a 2000 Yaris, they have had various engine management problems including visits to m/way hardshoulder twice, this resulting in numerous trips to the dealer, falling out with the dealer, numerous trips to the indy specialist and - I am sorry to say - recently nearly £500 in ECU components.
If you find another fix post it here and I will pass it on in case parts have just been thrown at it.

If only they'd bought a Ford instead... ;-)

Perhaps however a relevant comparison would be our Clio which is exemplary relative to the Yaris.

I have found the socket, its white and is positioned in the drivers side footwell just past the bonnet release lever.
You mentioned a basic reader that can be bought. Is there any specific reader I need for the EOBD11 system or do all readers read all codes. Are there any you could recommend, basic ones as well as the more advanced that allow you to see/change a little more information from the engine.
Thank-you

Hi
I'd be inclined to reset the ECU (disconnect the battery for 5 minutes or more) and see if the light comes on again when you drive the car before investing in any kit. As other have said, the warning is probably because you left the petrol cap loose.
If you want to have a look at readers, www.gendan.co.uk seem to have a range of reasonably priced kit and their site will give you an idea of what is available regardless of where you shop. As ever, there are all sorts of options on eBay but you'll have to research before buying.

Scan tool GS400 (under various brand names) on Ebay is a good one to go for. It has CAN and therefore covers pretty-much anything you can show it, including the very latest cars. CheckEngine is a decent package for a laptop, if that's what you want. You then have the choice of various ELM interface cables.
Scangauge II is an interesting little device which can be used as a code reader, but also can sit on the dash and give you engine data, fuel consumption etc etc. 'Blend mount' is a little ally bracket arrangement which allows you to fix it to your interior mirror - can look quite neat. Some of the Jap sports car lads fit these and they seem to work welll - never actually tried one myself though. Order from the US via Ebay.
