FI error codes, motorcycle Honda cbr 600 F4i

Owners of cbr 600 F4i, if you have to face such a problem as a flashing FI (MIL) light.

These short and long blinks are the same error codes. Each blink carries a certain number, which in turn will tell you about your malfunction. Long flashes (1.3 seconds) - the number 10, short (0.5 seconds) - the number 1.

For example: the light flashes twice at 1.3 and once faster (0.5 seconds). This tells us that error code 21 is a bad O2 sensor (California only). If twice quickly (0.5 seconds) - code 2, the MAP sensor vacuum hose is loose or disconnected, the MAP sensor is faulty.

Error codes and their interpretation

Code (MIL)	Cause	Symptoms
Lights up constantly	There is a jumper in the service connector ; the control unit (ECM) is not working; a short circuit in the service connector	Engine running fine
Does not glow	ECM Power Break Faulty Tilt Sensor Faulty Tilt Sensor Circuit Faulty Engine Stop Relay Faulty Engine Stop Relay Circuit Faulty Engine Run Switch Faulty Open Engine Stop Switch Circuit Faulty Ignition Switch Faulty ECM Faulty PGM-FI (20A) Fuse Blown ignition (10A)	Engine won't start
Does not glow	open in the MIL indicator circuit Faulty ECM	Engine running fine
one	Loose or missing MAP sensor contact MAP sensor circuit open MAP sensor defective	Engine running fine
2	MAP sensor vacuum hose loose or disconnected MAP sensor defective	Engine running fine
7	Loose or missing FCT sensor contact Open or short in ECT sensor circuit Faulty ECT sensor	Difficulty starting the engine at low temperatures
eight	Loose or no TP sensor contact Open or short in TP sensor circuit Faulty TP sensor	Poor engine response to throttle opening
9	Loose or no IAT sensor contact Open or short in IAT sensor circuit Faulty IAT sensor	Engine running fine
eleven	The speedometer sensor contact is loose or not Open or shorted in the speedometer sensor circuit The speedometer sensor is faulty	Engine running fine
12	Loose or no injector connector contact #1 Open or shorted in injector #1 connector circuit Faulty injector #1	Engine won't start
13	Loose or no injector connector contact #2 Open or shorted in injector #2 connector circuit Faulty injector #2	Engine won't start
14	Loose or no injector connector contact No. 3 Open or short circuit in the injector connector circuit No. 3 Injector No. 3 is faulty	Engine won't start
15	Loose or no contact of the injector connector No. 4 Open or short in the circuit of the injector connector No. 4 Injector No. 4 is not working	Engine won't start
18	Loose or no contact of the pulse generator sensor connector Open or short circuit in the circuit of the pulse generator sensor connector Faulty pulse generator sensor	Engine won't start
19	The contact of the impulse sensor of ignition departs or there is no open circuit or short circuit in the circuit of the impulse sensor of ignition The impulse sensor of ignition is not working properly	Engine won't start
21	Faulty O2 sensor (California only)	Engine running fine
23	Faulty O2 heating sensor (California only)	Engine running fine
33	Damaged E2-PROM in ECM	Engine runs normally Self-diagnosis not stored

I also want to add - PGM-FI memory. System errors are stored in this memory, which can be viewed as follows:

- Turn off the ignition "OFF"

- Put a jumper in the service connector, which is located near the battery and has two wires.

- Turn the ignition "ON" and switch the "stop" switch to the "run" position

After that, if there are errors in the memory, they will blink off again. If there are no errors in the memory, then the FI indicator will simply glow.

And one more nuance and you can complete the article) If the error is not one, but several at the same time, then first FI will blink from the lowest digit of the code to the highest with a pause.

Reset errors, how to do it?

Turn the start-stop button to the run position, the ignition switch is off. Next, short the diagnostic connector with a jumper. Turn on the ignition switch. After turning on the ignition, remove the jumper. The indicator should light up for 5 seconds. While it is lit you must insert the jumper back. (All this must be done within 5 seconds). A sign that the memory has been erased is the error indicator goes out and then starts flashing. Please note that the memory will not be erased if the ignition switch is turned off before the indicator starts flashing. And lastly, if the Indicator blinks 20 times, then the memory has not been erased and you need to repeat it all over again.
