F1 light

Could a bad 4-way flasher switch affect the F1 light?

No ... the FI light (fault indicator) monitors PGM-FI (programmed fuel injection system). Basically the system includes sensors that send a signal to ECM (engine control module) to change air/fuel mixture and ignition timing. It has nothing to do with the turn signal circuit.

What year is your Wing and what are your symptom.

thx for responding.
2003 GW Trike. At speed on inter-state 78-80 mph F1 light came on, bike ran normally, got home, shut down, started 4X F1 light went out normally. Does the light re-set each time the bike is shut off? If so, I'll have to take it for a ride & get some miles on it. Replaced w/new ECM 2 years ago.

The fault only clears by following a procedure. To do that requires removal of the seat and shorting 2 wires together with the use of a special connector, and following a list of instructions.

The FI light only comes after or while the fault occurs. In most cases, once it come on, it will stay on until the ignition switch is cycled off. However, just because it is on, does not mean that the fault continues to occur. It means that it did occur or still is occurring. It is normal for the FI to come on during startup for about 5 seconds. During that time the PGM-FI is going through a self check. Once the self check is complete, the FI light should go out until a fault occurs.

While riding, do this the next time it comes on. Pull over, put it in "N", and lower the side stand. Do not turn it off. That should trigger the FI light to begin to flash. A long flash has a value of 10. A short flash has a value of 1. There can be more than one code stored. Between each code is a long pause. If you miss count, don't worry, the flashes will continue until you turn the key off ... so take your time and get your count correct and report back.

example: long long short short short short short = 25

Check the codes. I had a similar problem on my ST1300 indicating a knock sensor problem, Turned out I had to replace the ECM to correct the problem.
