FUEL INJECTION SYSTEM
SUBSTITUTE CHARACTERISTICS OPERATION CONTROL (FAIL-SAFE ACTION)
If the ECU detects an abnormal signal from a sensor while the motorcycle is being driven, the ECU
illuminates the engine trouble warning light and provides the engine with substitute characteristic
operation instructions that are appropriate for the type of the malfunction.
When an abnormal signal is received from a sensor, the ECU processes the specified values that
are programmed for every sensor, in order to provide the engine with substitute characteristics
operation instructions that enable the engine to continue to operate (or to stop its operation,
depending on circumstances).
The ECU takes fail-safe actions in two ways: one in which the sensor output is set to a prescribed
value, and the other in which the ECU directly operates an actuator. Details on the fail-safe actions
are given in the table below.
