Im using a Lancer 1997 GLXi. About 3 years ago, the speedometer and odometer ceased functioning. I discovered that they would work again once I disconnect the battery and reconnect it (parang "reset"). Even the odometer reading seems to have catched up with the lost mileage. However, about a day after the reset is made, the problem will go back with the speedometer reading staying at 20kph regardless of actual speed.
This year, I decided to fix the problem. I bought a new speedometer and odometer. They worked fine for the first few hours until the exact same symptoms came back.
I heard that many other people suffered with speedometer/odometer problems on their mistubishi lancers, stradas, etc.
What could be the cause of this? Does anyone have any idea how to fix this? Where can I have it fixed?
