Jump into the drivers seat and turn the key twice (so lights are up on the instrument cluster).

If you bridged out the correct wires 'Check Engine Lamp' will be flashing (the engine fan will also run - this is normal).

The flashes are divided into 2 groups with roughly a second between each. You can read the flashes as follows:

The first series of flashes is tens, so for example lets say the first flash simply flashes once, this means the code is 10. After the pause (~1 second) a second series of flashes will appear, if this number is 2, the code it is spitting out is 12 which means everything is fine.

Another example:

The first series of flashes you count is 4 meaning 40, the second series of flashes is 3. Adding the 40 and the 3 will give you a code of 43 which means the Knock sensor circuit is experiencing problems.

Each code the computer picks up is repeated three times with ~3 second pause between, so its wise to sit there to make sure there isn't any problems it has picked up.

Once you are finished turn off your ignition and remove the paper clip. It is important to note not to drive the car around while have wires are bridged as this will prevent new codes from being logged.

Everyone will get a 12 first. If you get a 12, 3 times, then it repeats the 12 again 3 times that is indicating that there have been no logged faults. If you only checked the 12 and didnt wait 2 seconds after the 3rd 12 flash than there may possibly be more fault codes. But if 12 is the only log than there are no recorded problems. This does not mean there are no faults, just none that have been read by the computer.

To clear the error log remove the engine fuse, 20A, under the bonnet near the battery for a few seconds.
