The EFI should come on for about 5 seconds. If it stays on, you are about to lose the rectifier, battery and halogen headlight. When the EFI light stays on, it's telling you that the rectifier is failing. If you continue to oiperate the bike, it WILL quit. It will cook the battery and leave you stranded.

If this is a 500 then it's using the Piaggio x9500 engine, it's fuel injected, efi is 'electronic fuel injection'

that light must be a warning that one of the sensors is playing up, aire temp, air flow, throttle postion etc. take it to an Aprilia dealer, they have a test box they plug in to the wiring and it tells you what is at fault. Piaagio dealer might be able to check it as well, they use a device called a texa navigator, could save you a load of grief. biggest problem with the x9500's was under the footboard, the main control box (ecu) has one big block connector for the wiring, this got full of water spray and corroded badly. if the dealer's test box comes up with multiple faults, it's probably that connector which makes false reading, says everything is knackered.

Have you pulled the error codes?

1- Turn Ignition switch to OFF & Run/Stop switch is to Run.
2- Push odometer reset button in & hold.
3- Turn ignition switch to Ignition and release odometer reset button. Background lighting sould illuminate, speedometer needle should sweep its full range and indicator lamps (battery, security, low fuel, check engine and cruise) should illuminate. The word "diag" should then appear.
4 - Push the odometer reset button once and you will see the selection menu "PSSPt" with the first P flashing.
5 - Each letter represents an area of the diagnostics module. The module that is flashing is the one you are going to check. To move from one letter (module) to the next, you push the odometer reset button one time. (from P to S to SP to t and back to P, etc.)
P = ECM/ICM (Electronic Control Module [EFI] / Ignition Control Module [Carbureted])
S = TSM/TSSM (Turn Signal/ Turn Signal Security Module)
SP = speedometer
T = tachometer
6 - To get the DTC within an area of diagnostics, push and hold the odometer reset button in for 5 seconds and release. If there are any DTC's the code will be displayed or the word "none" will appear if there are no DTC's. Push the odometer reset button again to view additional codes if they exist.
7 - Record the codes.
8 - If DTC's are not to be cleared, Press and release the odometer reset button. Part number of module will be displayed.
NOTE: To determine if a code is current or historic, clear the displayed code by pushing in and holding the odometer reset button ( longer than 5 seconds) until 'clear' comes up. Release the odometer reset button. Turn OFF the ignition switch. Run your bike and shut it down then recheck the DTC's again by repeating steps 1 to 9. If the code is current it will reappear.
9 - Press and release the odometer reset button to continue to the next module.
10 - Turn Ignition switch to OFF.

How to UEFI mode? Based on Computers

  1. Use Device Manager's Firmware option and select Boot from EFI Internal Shell.
  2. Use the EFI internal shell, as follows:
    1. Start the EFI internal shell from the EFI boot menu and select the drive with the Windows product DVD or Windows PE. The following example assumes that the drive is Fs0:

      Shell> Fs0:
    2. Start the EFI boot application. For example, on an x64 system, run the following command:

      fs0:> \EFI\BOOT\BOOTX64.EFI For an Intel Itanium system, run the following command:

    3. After the application starts, you may be immediately prompted to press a key to boot from the drive to continue. Press a key to continue booting from the installation media.

    4. After the installation is complete, you can check whether Windows used the EFI boot environment by running DiskPart and verifying that the drive is formatted using the GPT file structure and that the ESP and MSR partitions are present.

I have a 1991 Toyota MR2 that will not start.

The EFI fuse is for fuel components, and for powering up the ecu. There is a lot on that circuitry. The 15 amp fuse, is also the power for the EFI relay. If this relay is without the power from that fuse, you probably won't have the fuel pump working, and the ecu won't be fully powered up.
Check the fuse again to see if it blew out again. If it did, you will have to trace the circuits for a short. Also, the EFI fuse gets power from the 40 amp AM2 fuse, so if the EFI fuse has power to it, the AM2 fuse is okay.
If I were you, I would test and check all fuses in all fuse/relay boxes under the hood. checking fuses is easy with a cheap test light. With the key in ON, every fuse on the car has power to it. So you clip tester light to ground (use neg. batt'y post), and then use test light probe into the little slot on the top end of a fuse. You do not have to take fuse out to visually inspect.
On the top end of all fuses are 2 little slots (one at each end of fuse) that is open to the metal strip inside. So you turn key to ON, then probe one end of the fuse. The test light should light up. Even a blown fuse will light up tester on one end of the fuse. Now to test the fuse itself, use the probe and touch into both ends of the fuse. A good fuse will light the tester on both ends of the fuse. A blown fuse will only light up one end of the fuse-the metal strip has blown so no power on both ends of the fuse, SEE?
And by using the test light, you also verify that power is getting to
the fuse. It is easy, and you are on the way to becoming an automotive electrician. Next, you need to buy and use a multi-meter, for automotive uses buy a digital volt-ohm meter (DVOM), which is what most multi-meters really are. And you don't have to buy an expensive one. I have a Sears Craftsman DVOM, about 20 years old, and it only cost like $30.
