ok, this is from memory.
Locate the diagnostic port.
It is below the steering column, on the drivers side.
It is a small panel you open and it will drop down with a grey plug.
Have a look at the back of the plug.
You will see 2 wires next to each other on their own.
That's the two wires you need to connect via the paper clip to get it working.
Turn the car to accessory mode.
Short the 2 wires on the diagnostic port.
You will see the lights on the dash flash (I think it's the check engine light)
long flash is the first number
short flash is the second number
example
21.
flaaaaaaaaaash

I think the end of codes code is 55.
This is ALL from memory, so I might be wrong on some parts.
Let us know how it goes.
