Has anyone got the s/w & wiring diagram for the astra ECU connection?

I've got an intermittent fault with my ABS / Traction control. Want to know what the computer says before i take it to a garage.

If not, anyone any idea where i can get a cheap but decent fault code reader?

if you have pin 6 on dlc you can read the flash code on the mil lamp

damn, my problem is ABS / Traction and the only fault code is "failed unit". Was hoping for failed sensor on wheel X as it also affects the speedo when it fails, then it turns off traction / abs and speedo goes back to normal.

Worthwhile checking the wiring at the sensors, their connector which is probably on the shock body and blasting the sensor with water to clean them up.

had a quick look under the car in case i could see some wires hanging loose. Couldn't didn't really wnat to get too involved. I have very little space to play with the real car & almost less motivation. Just wanted an idea of what to expect. Should look as its very irratic, usually comes on after a period of driving, but hasn't done it for a few days.
