Post Need help with FI indicator...

Hi All,

Could please somebody help with FI problem?

My dad has a GL1800 (got it from USA last year) and when out riding the FI light is coming on after a while. He can also notice a wee lack of power. After switching off ignition and restarting engine light is out but after some time it turns on again. He noticed that it's taking shorter for light to turn on when temperature outside is higher.

I spent last few days on internet and reading Manual and spoke with him about reading error codes but the thing is that when he put on neutal and put side stand down bike just cut out. I sked him to doubble check but Bike was not in a gear.

I can't find any information what to do in this case...

All help will be most apprieciated!!!

Thank you,

Lasaria

Hello and welcome to the forum.
The IAT or Intake Air Temperature Sensor may be bad or out of spec.
Check the gear position sensor.

you must have motorcycle scanner to pull codes from computer

What year is the Wing in question?
If you have the service manual, pull the IAT and test it to see if it is within spec as per the manual.

AS 2003 says, you need the Honda digital diagnostics to identify the code(s) stored in the bike's computer. Not sure if you can check th IAT as trike lady suggests without the link-up. What year is the 1800? It should still be under factory warranty if it's an '08 or newer; got a VIN#? I can see if I can access it through my system.

If it's an 01-03 you can use a jumper wire.
If you isolate the component from the system you can test it. I've tested O2 sensors off the bikes and found out if they are with in spec.
04 and newer I have an SCS and an H685.
In the service manual you can check the resistance of the IAT off line (2001-2005 p5-23) may possibly be checked the same way for resistance on newer models.

The codes for the PGM-FI

If the FI light (Programmed Fuel Injection (PGM-FI) Malfunction Indicator Light (MIL)) comes on pull over but DO NOT shut bike off. Put in neutral and put side stand down, RPM’s below 1500. This signals the ECM to send the error code to the MIL. Count the number of long and short flashes. This will give you the error code.

If you shut the bike off the error code is lost - sort of. It will be retained in the ECM but it is harder to get out. If the bike stops and then will not restart you can get the FI light to flash the error code by cranking the engine for 10 seconds. The FI light will then flash the error code.

Long Blink = 10 Short Blink = 1
i.e. long long long short short short = 33 check error code 33

Number of MIL blinks. Symptoms and cause

Thank you all very much for advices!!! It's most apprieciated!!!

Wing is from 2008 (VIN 1HFSC47LX8A704080) but I'm affraid servicing it will be a wee bit tricky as it was in an accident in America, still broken shipped to Poland, repaired and then bought by my Dad.

He told me that Air Filter cover on right side is not original (it was adapted from left side cover) so IAT idea seems right. This would explain why when outside is worm FI lights up sooner than in colder weather.

I'll work with my Dad and manual in this same time and we will check this IAT :0)

He will really have to start completing original parts and have general check as he plans trip around a Europe in September!

Thank you very much for your help one more time!
