What is the motorcycle ECU power-off reset method?

Ensure the engine kill switch is in the ON position. Turn the ignition key ON and immediately OFF, then wait for 20 seconds. Cycle the ignition key ON and OFF five times at a rate of one cycle per second. Wait for 20 seconds, then turn the ignition key ON. If the yellow malfunction indicator light on the instrument panel does not illuminate and the fuel pump operates normally, the reset is successful.

I've found that ECU power-off decoding is simply a method of resetting the ECU by disconnecting the motorcycle battery. I often use this technique when repairing my own bike. When the engine throws an error or shows unstable performance after modifications, disconnecting the negative terminal for a few minutes and reconnecting it allows the ECU to forget temporary errors and readjust, just like rebooting a computer. The whole process is simple and safe - just park the bike on level ground and turn off the engine before performing the operation. However, remember this doesn't fix hardware issues, and you might lose clock settings, so note them down beforehand.
