Most countries have their own regulations, so each ECU
has different characteristic. So, do not confuse ECU with
each other and use only the ECU for your model. Other-
wise, the motorcycle cannot clear the regulation.

Never drop the ECU especially on a hard surface.
Such a shock to the ECU can damage it.
When replace the ECU with a new one or reused one
from another motorcycle, you must register the accel-
erator position and throttle position data of the throttle
body to the ECU.
For immobilizer equipped models, register the ignition
key correctly before doing the following procedure (see
Key Registration in the Electrical System chapter).
1. In the new ECU, wait the 10 seconds at the idle speed
and the coolant temperature 40°C (104°F) or more to
register the sensor position to the ECU.
2. In the reused ECU, erase the stored service code mem-
ory using Kawasaki Diagnostic System (KDS Ver.3), and
wait the 10 seconds at the idle speed and the coolant
temperature 40°C (104°F) or more to register the sen-
sor position to the ECU.
