Mitsubishi Repair Problems? Ask a Mechanic for Answers ASAP
Was it the engine battery or key battery that was replaced?
The chip in the key should not be affected by the engine battery being changed normally.
When you try to start the engine, it cracks but does not start, or does it not crank either?
If it cranks but doesn't start, does it sound abnormal (faster or slower than normal)?
When you turn the key on does the service engine soon light still do it's bulb test?
Are there any other electrical malfunctions you can see?
Thanks.The vehicle has two factory security systems.... the immobilizer in the key which causes the fuel to cut if it does not match (and is RFID based, completely independent of the battery) and the wireless system that simply sounds the horn and lights when tripped. Neither should be impacted by the battery being disconnected unless there is an add-on module.That said... to disarm it you would only either use the button on the key or use the key to unlock the drivers door twice. Those are the over ride measures for the factory system.Do you have a second key you could try for comparison? Do you have a test light or meter?
No problem, and no second key then I take it?How about a meter or test light?
I understand.Lets take a visual inspection of your larger fusible links... these are the bigger fuses under the hood in the fuse box and specifically the one hanging off the positive battery post. Lets look to see if any of these are visibly broken (you can look through the window on the top of each). Also lets double check if you disassembled the positive battery terminal that all cables got reattached.
