How to get error codes from a Kawasaki motorcycle?
Here are instructions on how to retrieve error codes from your 2001 or newer Kawasaki street bike.
Remove the seat and next to the negative battery terminal there will be a self-test output from the connector. The wire is yellow. It looks like it.
Step 2 Take the wire, I use one with alligator clips on both sides. Makes things a little easier.
Attach the crocodile clip to the yellow wire.
Step 3 Turn the ignition key to the "ON" position and wait a few seconds for the start procedure to complete.
Step 4 Connect the wire to the negative battery terminal (ground).
Step 5 Watch your FI light. It will start flashing with long and short flashes.
Step 6 You will now interpret the flashes into a numerical value using the following table.
Interpretation of error codes The FI indicator will flash long and short flashes.
Long flashes correspond to values from 10 to 90.
Short flashes represent 1-9
If you get three long flashes followed by 4 short ones, the error code is 34 and you can check the table.
When there is a problem with the ignition system and DFI
system, check engine light [A] (LED) flashes.
Use a fully charged battery when carrying out
self-diagnosis. Otherwise, light (LED) and symbol
blinking very slowly or not blinking.
• Turn the ignition key to the ON position. • Press the left button  to display the odometer.
3-34 FUEL SYSTEM (DFI)
• Press the left button  for more than two seconds. • service code [B ] is displayed on the LCD for a number
from two numbers.
• Any of the following procedures ends with self-diagnosis.
○ When the service code is displayed on the LCD, press
Left button for more than two seconds.
○ When the ignition key is in the OFF position.

Reading service codes
○The service code(s) is displayed on the LCD as a two-digit number.
○ When there are a number of problems, all service codes can be saved and the display will start
starting from the lowest service code is ok .
○ Then after all codes are completed, the display is repeated until the ignition key is turned off or
The left button will be pressed for more than two seconds.
○ For example, if three problems occurred in the following order: 56 , 13 , 31 , service codes
displayed ( every two seconds ) from the lowest number in the specified order , as shown below .
(13 → 31 → 56) → (13 → 31 → 56) → (repeated)
○ If there are no problems or when an overhaul has been done, the engine warning light (LED) goes out, and
service tag is not displayed.
Service Code Erase
○ When an overhaul has been done, the check engine light will not show service codes anymore.
But the service codes stored in the ECU's memory are not erased to keep the problem history.
In this model, the history problem cannot be erased.

○ECU may be involved in these problems. If all parts and circuits are checked well, be
Be sure to check the ECU for ground and power. If ground and power are checked
ok, replace the ECU.
○ If no service password is displayed, the electrical parts of the DFI system has no faults, and
the mechanical part of the DFI system and the suspect's engine.
