i would like to know where i can get the test codes on the dash test. i am unsure what the numbers and things are if any body can give us a clue has to the letters and numbers that come up i will be most greatfull

Most of what comes up on the dash test is just the raw data that the dash has received from the ECU and means very little.
If you want to read codes properly you need to plug a module into the OBD port.

It's a waste of time as any fault codes it gives u will only relate to the clocks themselves
