Hello and Welcome..
My name isXXXXX happy to help you..
I see you say you disconnected the battery to try to reset it - if the light is still on / came back on, then the Ecu / command computer has detected and logged a fault - and hence your light is on. You cannot therefore just reset the light / ecu.. the "fault" whatever has been detected, has to be found first and fixed - then the light will go out.
So yes, a fault code reader is at least required to do as above.
Most small type garages can run the test for you - you dont have to use a dealer and that will be your cheapest way forward - unless you want to buy / use your machine of course..
Hello there - I see you joined me..
I typed your answer to your question out above - can I help you anymore with this at all while we are in Live Chat?
i have machine but canot find where to plug in as fault has been repared
right ok - they put them in different places - usually the Corsa is in the fuse box - give me your reg number and I'll double check for you on your exact car...
In your question you wrote - "a 94 Corsa" - thenn in the vehilce details you say "03".. so I need to be sure what you have..
Ok - give me a min..
Ok - the diag socket on your particular car is behind the panel ( some have an ash tray or bucket) forward of the gear stick.. bottom of the dash there.
Prise whatever you have out - and its there - you will see it clearly.
Is that ok for you or do you need anything more ? I can send you a drawing of its location if you need -
FOUND IT THANKS MIKE
