Servicing the Electronic Fuel
Injection System
This machine contains an electronic fuel injection
system. It controls the fuel flow under different
operating conditions.
The electronic control unit (ECU) continuously
monitors the operation of the EFI system.
If a problem or fault within the system is detected, the
malfunction indicator light (MIL) is illuminated. The
MIL is the red light located in the console panel.
Once the MIL illuminates, initial trouble shooting
checks should be made. Refer to the MIL section under
Toubleshooting.
If these checks do not correct the problem, further
diagnosis and servicing by an Authorized Service Dealer
is necessary.
