If the 2001 Mitsubishi Mirage won't start and has the service engine light on, you probably have an issue with a sensor. This could be a problem with an electrical or oxygen sensor.
How do I get the code
supplemental restraint system
DISCONNECT THE NEGATIVE BATTERY CABLE
In order to fix a Mitsubishi mirage signal light that doesn't turn off, you would need to understand the wiring system. This is a problem with the wiring and the circuit that connects the power from the battery to the signal light.
The proper course of action is to have the car serviced by an authorized garage, who will reset the service light when they're done.
If not installed properly check engine light will illuminate
service engine soon you have a problem with your car that your ECM has detected
I HAVE A 2004 MITSUBISHI ENDEAVOR, AND THE ONLY TIME MY CHECK ENGINE LIGHT CAME ON IS WHEN I FAILED TO CLOSE MY GAS CAP TIGHTLY. THE LONGEST THE LIGHT STAYED ON WAS FOR 3 DAYS AND THEN IT WENT OFF.
The owners guide for my '04 Endeavor says do not disconnect the battery I think, or the on board diagnostic record will be lost. maybe this would also clear the service engine light?
Right under the hood release button to the left
the fuse box is located in the engine bay, its a black box with a diagram on it on the drivers side ( japan model ) the dashboard fuse is a 20amp yellow fuse.
The service engine light is the same thing as a check engine light.
