PGM-FI light on

[abtx]

Hello. Today after riding for about 30 minutes I got the PGM-FI light on. Pulled over, switched it off and on again after couple minutes. The light was gone. Another 30 minutes to get back home, the light was off all the way.

Should I check the battery first, or take it straight to the garage?

Or is there anything else I can do to test what this could be?

Cheers!

PS: just started the bike to get it parked back for the night, seems fine, no lights. I watched a video on reading fuel injection codes and none of those are relevant. My light went on solid and was on till I switched the bike off, and then just gone on the next start. Weird.

Update

Checked the battery with multimeter and it's charged up.

No need to involve a garage, the joys of owning a CBF1000 is the ease in which it can be serviced and maintained at home by the home mechanic without the need of any special tools or diagnostic equipment. If you’re allowed spanners and you haven't already, you may want to download the Honda Workshop and Owners Manuals here.

If the PGM-FI light comes on this indicates a PGM-FI malfunction, the proper term for the PGM-FI light being Malfunction Indicator Lamp (MIL). The Engine Control Module (ECM) will store a record of the fault as a current Diagnostic Trouble Code (DTC) which can be easily retrieved.

If the PGM-FI light comes on and later goes off this indicates an intermittent fault, that is the fault only exists when the light is on, when the light is off the fault is no longer present but may be of some concern. Again the Engine Control Module (ECM) will store a record of the fault as a stored Diagnostic Trouble Code (DTC) which can be easily retrieved.

Current DTC's are indicated by the presence of the MIL, stored DTC's should be checked for at each service.

While you're there you may as well check the ABS system for any stored DTC's, another earlier post 'How to read ABS Diagnostic Trouble Codes here'

Hi Art

Brilliant advice, thanks a lot for sharing. Will check these guides out and see what I can read from my CB.

Appreciate it 🙏.

So I’m looking for Data Link Connector so I can read stored codes but I can’t find it. Do I need to remove the battery?

no need to remove the battery, the thread I linked too explains where the DLC is on the original SC58 model (Remove the seats...)

I've now added the location for the DLC on the face lift SC64 model, or you can refer to the Honda Workshop Manual section 5 page 15 (Lift and support the fuel tank...)

I guess mine might be SC64. Thanks again for the pointers!

Yes, if that's a photo of your battery yours is the later (2010 to 2013) SC64 face lift model. You'll find the DLC on the right hand side under the petrol tank as above.

Hi Art

I've not gotten round to reading the codes just yet, took the bike out and it rides as normal, no faults.

It got me thinking that time the light came on I kept the bike in low rives for that 30 minutes ride, doing ~20-60.

I'm probably going a bit on the tangent here, but I got the bike recently, and this is the first bike I own that sounds like this (

) when idling. Is this idle sound normal for a CBF?

It can be quite a task to locate that DLC connector on SC64 without lifting the tank. Mine was wrapped in insulation tape and it took me a while to figure out its location and how to pluck it open :)
To make it futureproof I bought a plug with a switch on a cable lead: https://www.ebay.co.uk/itm/283741177977 and run that cable up so the switch is accessible from under the rider's seat - this made future diagnostics much easier.
