1. Battery Drainage:
- Check the battery terminals for corrosion or loose connections. Clean and tighten them if necessary.
- Have your battery tested at an auto parts store or a mechanic's shop to determine if it needs to be replaced.
- Check for parasitic drains by turning off all electrical components and accessories and then measuring the current draw with a multimeter. If the draw is higher than normal, there may be a faulty component or circuit that needs to be addressed.
2. Engine Idling:
- Check the air filter and replace it if it's dirty or clogged.
- Clean the throttle body with a throttle body cleaner following the manufacturer's instructions.
- Check the spark plugs and replace them if they're worn or damaged.
- Check the ignition coils and replace them if they're faulty.
3. Radio Code:
- Check your owner's manual or the glove box for the radio code.
- If you can't find the code, you can contact your local Mitsubishi dealership and provide them with your vehicle's VIN (Vehicle Identification Number) to obtain the code.
- Once you have the code, enter it into the radio by pressing the appropriate buttons. The exact steps may vary depending on the specific model of your radio.
If you're unable to resolve the issues yourself, it's best to take your vehicle to a qualified mechanic or an authorized Mitsubishi service center for diagnosis and repair.
