I have an ongoing problem with my 22GT. I have taken it to two different dealerships and they have not been able to diagnose the issue. Relays are good, continuity is good and the fan motors are good. When I get into traffic I know to switch over to the temp reading because if it goes a half bar above about 50% it will throw a check engine code. If I look at the fans they are usually stopped. They will sometimes kick on for a few weak revolutions and then stop again. I shut the bike down, wait a minute or so and restart. Sometimes the fans kick on, sometimes they don’t. Rinse & repeat.
They never seem to kick into high mode. When the traffic clears, the temp goes back to normal, so I think the thermostat is fine. After a few cycles of no traffic the check engine fault goes off. Until next time…. Grrr…
So, after looking at the downloadable repair manual/coolant system I found that it has a
PWM Controller. This regulates fan speed. Hmm… Computers use them and you may have heard your fan when it kicks into high mode. So, I ordered one this afternoon. Maybe that’s the issue or maybe not but I think I am on the right track. Thoughts? My issue now, don’t even go there
is that I can’t find how the replace the PWM Controller in the searchable database. Remove the cowling? Remove the radiator? Help! Please.
