1. Push and hold the trip/reset button
2. Turn the lighting switch on
3. Turn the ignition to ON(II)
4. Within 5 seconds, turn the lighting switch OFF, then ON and OFF again
5. Within 5 seconds, release the trip/reset button, then push and release the button 4 times

The beeper sounds 5 times. Then all the indicators blink. Then the odo/trip segment blinks 5 times. Then all the needles sweep from min to max back to min. Then it will run a communications check and display either all 8's or the word error. 8's are good, error means the connection between the cluster and ECM/PCM is bad. If anything doesn't work properly in test mode replace the cluster.
