FUEL INJECTION SYSTEM
In addition to identifying any current malfunction, the software
stores past malfunctions that have been resolved: store malfunc-
tions can be deleted following the instructions provided in the
Operation Manual.
The ECU stores the number of service hours of the engine (toler-
ance range: + / - 1 hour). The first equipment ECU also stores the
vehicle identification number (VIN) and engine number (engine no.)
of the motorcycle. If ECU is replaced, the new ECU will only report
engine service hours.
For fuel pump and relay inspections, see relevant paragraphs.
