I used this is my EF/EL's quite a bit, was a nice little novelty

Diagnostics for more models coming soon

this is pretty breezy, but its not my genius that did all this, came of another forum, so anyhoo:
this works 100% for VR-VS should be the same for VN-VP

Locate the diagnostic connector under the the steering column on the drivers side.



---------------------------------------------------------------

Grab a paper clip and bend it like this:



---------------------------------------------------------------

Bridge pins number 5 & 6 which are located on the top row counting from the left.




It should now look like this:



---------------------------------------------------------------

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 just so you're sure

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.

Any questions or queries please feel to contact me at anytime.

Checking the computer for codes is used in conjunction with the computer Fault Codes located here

Go for it buddy

Its slightly different on a VN-VP the ALDL connector is located under the passenger side kick panel.
