Hi, I have just obtained a 1997 el gli falcon and it had a few blown bulbs in the dash. Once I got them going it came up with a spanner next to the mileage. How can I get rid of this, what does it mean?. Is there a way to reset the ecu. The car seems to go fine and is not using any oil etc.

"Turn the ignition to 'ON' (engine not running) then press and hold the tripmeter reset button for approx 10 seconds or until the cluster 'beeps'."

thank you it worked instantly
