SERVICE ICON
The Service Icon is controlled by the CCU/ECU and may
illuminate for a number of reasons. The icon should illu-
minate each time the engine is started, and it should go
out after a few seconds. If the icon stays illuminated
while the engine is running, the CCU/ECU is receiving
input that is outside of its established parameters.

FZ003B

NOTE: If the icon illuminates while the engine is
running, the CCU is receiving input that is outside of
its established parameters.
Accessing CCU Codes
1. Connect the appropriate harness from CCU Diagnos-
tic Test Kit to the diagnostic port.
2. Start the engine.
3. After approximately 5 seconds, the service icon on
the gauge will begin flashing.
4. The readout screen will display an error code as
CCU followed by a number. When all error codes
have been output, the service icon flashes twice
quickly.

NOTE: Refer to the CCU Diagnostic Codes chart for
descriptions.
Clearing Fault Codes
1. Connect the appropriate harness from CCU Diagnos-
tic Test Kit to the diagnostic port.
2. Start the engine.
3. Press and hold the shift button for 5 seconds.

NOTE: Two quick flashes of the service icon indi-
cate the codes have been cleared.
VOLTAGE TEST

NOTE: The following test should be made using
MaxiClips and the Fluke Model 77 Multimeter set to
the DC Volt scale.

NOTE: The CCU tests were made with the connec-
tors plugged in, spark plugs removed and grounded,
and by pulling the recoil starter rope briskly.
LOW POWER
1. Connect the red maxiclip and meter lead to the red/
blue lead of the connector; then connect the black
maxiclip and meter lead to the black lead of the con-
nector.
2. Pull the recoil starter rope briskly.
3. Meter reading must be within specification.

NOTE: Repeat test three times to confirm results.

! WARNING
Most voltages generated by the ignition system are
sufficient to interrupt pacemakers! All technicians,
especially those using pacemakers, must avoid con-
tact with all electrical connections after the engine has
been started.
