If the reading is in specification, check the ECU for its ground and power supply (see ECU Power Supply Inspection).
If the ground and power supply are good, replace the ECU (see ECU Removal/Installation).
If the reading is out of the specification, remove the ECU and check the wiring for continuity between main harness connectors.

Break-in
The first 1 600 km (1 000 mi) that the motorcycle is ridden is designated
as the
break-in period. If the motorcycle is not used carefully during this period, you
may
very well end up with a “broken down” instead of a “broken in” motorcycle after
a
few thousand kilometers.
The fol ...
Immobilizer System (Equipped Models)
This motorcycle is equipped with an immobilizer system to protect the
motorcycle from theft. This
system provides a theft proof device by means of matching a code between the
inbuilt key transponder
and ECU. If the code does notmatch, ignition system, injectors, subthrottle
valve actuator an ...
