Self-Diagnosis Functions
The ECU is equipped with a self-diagnostic
function in order to ensure that the fuel
injection system is operating normally. If this
function detects a malfunction in the system,
it immediately operates the engine under
substitute characteristics and illuminates the
engine trouble warning light to alert the rider
that a malfunction has occurred in the system.
Once a malfunction has been detected, a fault
code is stored in the memory of the ECU.
(* For information about the deletion method,
see 2CR STD Service Manual.)
•
To inform the rider that the fuel injection
system is not functioning, the engine
trouble warning light flashes when the
start switch is being pushed to start the
engine.
•
If the self-diagnosis function detects
a malfunction in the system, the ECU
p er fo r ms an ap p ro p r iate subst itute
operation and illuminates the engine
trouble warning light (diagram "1"), and
the fault code number (diagram "2") is
displayed.
