To reset codes:
1. Turn on the ignition to the KPII position so the warning lamps on the dash are illuminated. Do not start the car.

2. Open the bonnet of the car and locate Diagnostic test port (A) behind the driver side headlamp.

3. Remove the cover and pull the jumper wire out of the holder in the cover.

4. Insert the jumper into terminal #7, then press button 4 times, wait approximately 5 seconds and the red lamp should glow continuously. You are now in the data reset mode.

5. Press the button 1 time and wait approximately 5 seconds for the lamp to glow again then press the button 5 times. After about 5 seconds the lamp will illuminate again, press the button 1 time and you will see the lamp flash repeatedly for a couple of seconds indicating that the service lamp has been properly reset.

6. If a mistake is made, simply switch the ignition off and back on to reset and start over.


If you put sensor in #7 and push the button once you will get a set of blinks. Count them...they are in a series of 3 with a pause between...ie: blink, blink, pause, blink, blink, blink, pause, blink= 2-3-1 code, etc.
