Resetting the check engine light
Here is how to reset your ECU without disconnecting your battery. This is a solution for those who install new parts and do not want to risk losing their trip meter mileages, radio presents, and so on.
- Make sure the car is off and that the key is not in the ignition.
- Open the hood and locate the "Engine Room Relay Box." This is the fuse/relay box in the engine bay. On the xA/xB, it is the black top box to the right of the engine bay.
- Take the black cover off and flip it over to read the embossed diagram. You want to look for the EFI fuse (not RELAY). On the xA/xB, the EFI fuse is 15 Amps. On the tC, the EFI fuse is 20 Amps.
On the xA, the EFI fuse is #4: - Using the fuse-puller (white piece of plastic in the box), pull the EFI fuse out and let it sit for 10-30 seconds.
- Pop the fuse back in the EFI fuse socket. Make sure it is properly seated and is uniform with the other fuses.
- Put the black cover back on.
- Cross your fingers, start up the car, and hope you don't pull another CEL (Check Engine Light).
- If you are successful in not pulling a CEL, I recommend you let the car for 5-10 minutes for good measure.
