Following are the instructions for checking for error codes and clearing them from memory:


FUEL SYSTEM (Programmed Fuel Injection)
7-9
PGM-FI (Programmed Fuel Injection)
SYSTEM
SELF-DIAGNOSTIC PROCEDURE
Fit the safety lanyard clip to the base of the engine
stop switch.

If the warning light and PGM-FI malfunction indicator
lamp (MIL) do not blink, the PGM-FI system has
no problem.

If the MIL and warning light blink, and the warning
buzzer sounds, the PGM-FI system has a problem.
Push the SET, MODE, ID SET or ID NO. switch for
more than 2 seconds to stop the warning buzzer.
Push the SET and MODE switches simultaneously
for more than 5 seconds to blink the failure code.

Read and record how many times the MIL and
warning light blinks and determine the cause of the
problem (page 7-12).

To read the ECM memory of problem data, perform
the following:

Pull the safety lanyard clip off of the engine stop
switch.

Remove the seats (page 2-4).
Remove the dummy connector from the service
check connector.

Connect the service check connector terminals with
a jumper wire.
Fit the safety lanyard clip to the base of the engine
stop switch.

Push the SET and MODE switches simultaneously
for more than 5 seconds to blink the failure code.
If the ECM has no problem data in its memory, the
MIL and warning light will come on and stay on.
If the ECM has problem data in its memory, the MIL
and warning light will start blinking.

Read and record how many times the MIL and
warning light blink and determine the cause of the
problem (page 7-12).

PROCEDURE
1. Remove the seats (page 2-4).
2. Connect the service check connector terminals
using a jumper wire.
3. Fit the safety lanyard clip to the base of the
engine stop switch
4. Remove the jumper wire from the service check
connector.
5. The MIL and warning light lights about 5 seconds.
While the MIL and warning light lights, connect
the service check connector terminal again with
the jumper wire
The self-diagnostic memory is erased, if the MIL
and warning light goes off and starts blinking.

The service check connector must be jumped
while the MIL and warning light lights. If not, the
MIL and warning light will not start blinking.

Note that the self-diagnostic memory cannot be
erased if you turn off the engine stop switch
before the MIL and warning light starts blinking.
If the MIL and warning light blinks 33 times, the
diagnostic memory has not been erased.
