Simple, as you know there are some simple tricks and you will not go the service center to pay and save the money for you to spend on anything else:
-the basic disconnection of the battery terminals for 5 minutes or a personal diagnostic tool, but you may already know this so:
a. turn ignition key on 3/4 (just before the actual start, but does not start only lights the dashboard) and within 5 seconds press 3 times the gas pedal to a stop. Turn off and remove the key, that is it!
b. hold the trip odometer button 5-10 seconds then turn on the ignition 3/4, but do not start, hold it there another 10 seconds. Now turn on and off and it is reset.
NOTE: not applicable for all makes and models.
