how to read error codes

[dan666]

hi,
alright so I've tried several times to check my vt for errors, ive read on here that its possible; i use a paper clip and i bridge pins 5 n 6 under the dash then turn car to on and i'm suppose to count the light flashes.

but this dosnt work, all that happens when i do this is i blow my ecu fuse and/or get serv. error so the car pretty much wont function at all. btw replacing the 10a fuse under the bonnet stops the serv. error and the car will funtion again (if anyone else is having the problem)..

but can any body help me?, would rather not have holden charge to do this, if it is possible to do at home

Not sure why you are blowing fuse unless you have the wrong plugs

thanks mate! worked that time. maybe i had the wrong pins..
i seem to be getting the following codes, so pretty sure i'm reading it right

12,31,43,92,12

then repeats
