Imam sljedeći problem sa Kymcom 300i. Odvezao se na posao 10-ak km. Sve uredno radilo. Na semaforu malo dizao spuštao okretaje. Stanem, podignem ga na centralnu nogaru. Okretaji skaču gore dole. Probam dodati gas, ne prima gas, trokira. Ugasim ga, probam ponovno upaliti a on mrtav. Okrenem kontakt opet ništa, ko bez akumulatora. Akumulator pokazuje 12,7-12,8 v, svi osigurači uredu.

Ovaj problem ti je vezan za dvije stvari. Senzor brzine ili loš akumulator. Ako je kazaljka na 0 km/h na graničniku najvjerojatnije je senzor, ako se kazaljka odletila ispod graničnika onda trebaš resetirati km/h. To se radi sljedećom procedurom. 1. With ignition turned off, disconnect the battery completely.2. Make sure your battery is fully charged. I charged mine overnight on my Optimate charger/conditioner.3. Reconnect the positive terminal fully.4. Switch ignition normal 'on' position.5. Press and hold negative connector to battery terminal, watching the dials as you do that. The dials will sweep, my speedo needle was the wrong side of the stop, so it swept anti-clockwise and came to rest on the correct side of the stop.6. Still holding the negative connector to the terminal, insert and tighten the bolt so that it is fully reconnected to the battery.7. Switch ignition off.8. If the dials have done a sweep as mine did, that is the reset completed.9. Test ride - my speedo is now operating normally. Performance is exactly as it was prior to doing the reset so it seems to have had no effect on the ECU at all
