Re: Trip Mileage Resets On Start-up ?
Yes, it's most likely that the battery is on its last legs.........have had a similar experience in the past.
It's worth checking the condition of the clamps to the battery terminal posts first. Disconnect the clamps and clean them and the posts with wire wool. Apply a liberal coat of copaslip to each (vaseline will also work) and then reconnect the clamps. If the problem still persists, take a trip to the local autofactors and ask them to test the battery for you. They'll be able to confirm its condition.
You may need to enter the security code after reconnect if you have a coded head unit.
