Hi Friends,

I’ve been dealing with a flashing F1 code for some time and have tried to clear many times. There’s nothing wrong with the bike. Is there anything I’m missing? I’m using the reset procedure from the manual.

Thanks,
Lefin

 

Hi and welcome to the forum. What is the FI code you're getting?

 

I’m getting lose or open circuit bad sensor for ECT. 7 flashes. I replaced the ECT with factory part and installed another ECM from another F4I I have and no new codes appear .

I’ve tried to clear the code way more then I should have.

Thx for checking

 

@lefin Can you describe exactly in detail step by step the process you follow?

 

IDoDirt,

I follow the procedure in the manual to the T. Jump connector, turn on ignition, unplug the jumper within 5 seconds of the light blinking and reconnect.

I think I might have figured it out. The original ECU up to 2004 is A12. After 2005 they added an O2 sensor and the ECU is L11. I have an L11 in use and think because the O2 sensor wiring to the ECU is missing not allowing the code to clear.

Is that a Smoking Joe F3 I see??

Thanks for your help!
Lefin

 

No, sadly it's not. The Smoking Joe was in 1996 and 1998. This is a 1997 F3.

You didn't indicate what year your model was. It doesn't make sense that one code would prevent the ability to clear another. Are you able to measure the Ohms from Pin 1 of connector B of the ECU (Green/Orange) wire to Pin 17 (Pink/Green) wire of the same connector? It should be 2.3 - 2.6k Ohms at 68 degrees F. A little higher or lower depending on the actual temperature.

 

I have 2 2004 F4I’s. the 06’ definitely has O2 sensor and came with the L11 ECU. Not sure about the 05’. I’ll check the resistance when I get back from some PTO. The 04’ came with A12 ECU.

 

IDoDirt,

I replaced the ECT sensor with a new factory part and the code still wouldn’t clear on the bike with the L11 ECU. I swapped the A12 ECU with L11 and no codes appeared on the A12. The L11 is for CA bikes I’m sure of so I’m going to try and short out the O2 sensor wires at the plug when I get time and try to clear the code again.

I’ll let you know how I make out.

Thx, Lefin
