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.
If these checks do not correct the problem, further diagnosis
and servicing by an Authorized Service Dealer is necessary.
