Pulling an ECU Code on 2008 ZX-10R?

I got a warning light and flashing FI symbol on my LCD last night. It went out but I need to pull the code and find out what's up. Anyone know the procedure on the Gen III's?

If I remember correctly these are the steps

1. Turn on key
2. Hit mode til the mileage of your bike is showing
3. Hold reset button til code is shown.

If that doesn't work post up and I'll look in the service manual.

My Gen3 did that today. I came to a stop, did a quick u-turn, and the FI light started flashing. It will stay on unless I pull over, turn the bike off for a second or two, and restart it - bingo the light goes off every time. Very strange but it's a computer that needs reset at times. This only happens on rare occasions so it's not going to the dealer.

Notes:
○The ECU may be involved in these problems. If all the parts and circuits checked out good, be sure
to check the ECU for ground and power supply. If the ground and power supply are checked good,
replace the ECU.
○When no service code is displayed, the electrical parts of the DFI system has no fault, and the
mechanical parts of the DFI system and the engine are suspect.

○The ECU takes the following measures to prevent engine damage when the DFI, ignition or immobilizer
system parts have troubles.
Service
Codes Parts Output Signal Usable
Range or Criteria Backups by ECU
11 Main Throttle
Sensor
Output Voltage
0.2 ∼ 4.8 V
If the main throttle sensor system fails (the
output voltage is out of the usable range,
wiring short or open), the ECU locks ignition
timing into the ignition timing at closed throttle
position and sets the DFI in the D-J method.
12
Inlet Air
Pressure
Sensor
Inlet Air Pressure
(Absolute)
Pv = 50 ∼ 910 mmHg
If the inlet air pressure sensor system fails
(the signal is out of the usable range, wiring
short or open), the ECU sets the DFI in the
α-N method (1).
13
Inlet Air
Temperature
Sensor
Inlet Air Temperature
Ta = – 30 ∼ + 100C
If the inlet air temperature sensor system fails
(the signal is out of the usable range, wiring
short or open), the ECU sets Ta at 30C.
14
Water
Temperature
Sensor
Water Temperature
Tw = – 30 ∼ + 120C
If the water temperature sensor system fails
(the signal is out of the usable range, wiring
short or open), the ECU sets Tw at 80C and
the radiator fan operates.
15
Atmospheric
Pressure
Sensor
Atmospheric Pressure
(Absolute)
Pa = 50 ∼ 910 mmHg
If the atmospheric pressure sensor system
fails (the signal is out of the usable range,
wiring short or open), the ECU sets Pa at 760
mmHg (the standard atmospheric pressure).
21 Crankshaft
Sensor
Crankshaft sensor must
send 22 signals to the ECU
at the 1 cranking.
If the crankshaft sensor fails, the engine stops
by itself.
23
Camshaft
Position
Sensor
Camshaft position sensor
must send 1 signal to the
ECU at the 2 crankings.
If the camshaft position sensor system fails
(the signal is missing, wiring short or open),
the ECU continues to ignite cylinders in the
same sequence following the last good signal.
However, it can not be restarted after the
engine was stopped once.
24 Speed
Sensor
Speed sensor must send
30 signals to the ECU at
the 1 rotation of the output
shaft.
If the speed sensor system fails (no signal,
wiring short or open), the speedometer shows
0.
25
Gear
Position
Switch
Output Voltage
0.2 ∼ 4.8 V
If the gear position switch system fails (no
signal, wiring short or open), the ECU set the
top (6th) gear position.
31
Vehicle
-down
Sensor
Output Voltage
0.2 ∼ 4.8 V
If the vehicle-down sensor system has failures
(the output voltage is out of the usable range,
wiring short or open), the ECU shuts off the
fuel pump relay, the fuel injectors (primary and
secondary) and the ignition system.
32 Subthrottle
Sensor
Output Voltage
0.2 ∼ 4.8 V
If the subthrottle sensor system fails (the
output voltage is out of the usable range, wiring
short or open), the ECU drive the subthrottle
valve to the full closed position, and it stops
the current to the subthrottle valve actuator.

must use register key.
If the blank key or broken key is used, the
vehicle is no start and run.
39 ECU
The ECU send the data
(for gear position, service
code and key registration)
to the meter unit.

46 Fuel Pump
Relay
When the relay ON
condition, battery monitor
voltage 5 V or more

51 Stick Coil #1*
The stick coil primary
winding must send
signals 32 or more times
continuously to the ECU.
If the stick coil #1 primary winding has failures
(no signal, wiring short or open), the ECU
shuts off the injector #1 to stop fuel to the
cylinder #1, though the engine keeps running.
52 Stick Coil #2*
The stick coil primary
winding must send
signals 32 or more times
continuously to the ECU.
If the stick coil #2 primary winding has failures
(no signal, wiring short or open), the ECU
shuts off the injector #2 to stop fuel to the
cylinder #2, though the engine keeps running.
53 Stick Coil #3*
The stick coil primary
winding must send
signals 32 or more times
continuously to the ECU.
If the stick coil #3 primary winding has failures
(no signal, wiring short or open), the ECU
shuts off the injector #3 to stop fuel to the
cylinder #3, though the engine keeps running.
54 Stick Coil #4*
The stick coil primary
winding must send
signals 32 or more times

actuator.
64 Air Switching
Valve
The air switching valve
controls the flow of the
secondary air by opening
and shutting the solenoid
valve.

67
Oxygen
Sensor
Heater #1
and/or #2
(Equipped
Models)
The oxygen sensor
heater #1 and/or #2 raise
temperature of the sensor
for its earlier activation.
If the oxygen sensor heater #1 and/or #2 fails
(wiring short or open), the ECU stops the
current to the heater, and it stops the feedback
mode of the oxygen sensor #1 and #2 .
83
Oxygen
Sensor #2
(Equipped
Models)
The oxygen sensor #2 is
active and sensor must
send signals (output
voltage) continuously to
the ECU.
If the oxygen sensor #2 is not activated, the
ECU stops feedback mode of the oxygen
sensor #1 and #2.
Note:
(1) α-N Method: the DFI control method from medium to heavy engine load. When the engine load
is light like at idling or low speed, the ECU determines the injection quantity by calculating from the
throttle vacuum (inlet air pressure sensor output voltage) and engine speed (crankshaft sensor output
voltage). This method is called D-J method. As the engine speed increases, and the engine load turns
middle to heavy, the ECU determines the injection quantity by calculating from the throttle opening
(main throttle sensor output voltage) and the engine speed. This method is called α-N method.
*: This depends on the number of stopped cylinders

Does the warning have to be active to pull the code i.e. currently flashing or does the ECU store the fault for later retrieval even if no warning display is currently being displayed?

Sturner - thanks for all the good information, can you confirm from your service manual that the above is the correct method to extract the code?

I am getting the FI warning every ride now but only when starting up after the engine has been sitting for about 30 minutes. Cold starts are fine with no FI warning. It is virtually inmpossible to know what's up without the code. I am under warranty until December but I don't want to drop it off at the dealer just yet until I've taken a shot at it. It could be realated to the PCIII and TRE installation. Never had a problem with those before on any other bike though.

Thanks Guys, your help is greatly appreciated!
