USAGE
See Figure 4-8. The diagnostic menu is the primary system
menu (main menu) through which all other secondary menus
and displays are accessed. Since the screen may not be
large enough to display all line items at any given time, use
the up and down arrow keys to scroll through the list.
Checking Codes
1. See Figure 4-9. From the diagnostic menu, press num-
ber "2" to access the trouble codes menu. At this point,
the unit allows the operator to:
a. Press number "1" to display current trouble codes.
b. Press number "2" to display historic trouble codes.
c. Press number "3" to clear trouble codes. See
ing Codes below.
2. When examining trouble codes, write down all codes on
a piece of paper. If a current trouble code exists, place it
at the top of the list.
a. If trouble codes are present, see
the applicable flow charts for each code.
b. If trouble codes are NOT present, but starting or
driveability problems are evident, see symptoms
charts under 4.9 INITIAL DIAGNOSTIC
c. After reading current/historic trouble codes, simply
press the mode key to return to the trouble codes
menu.
3. Press the mode key again to return to the diagnostic
menu. In this manner, regardless of where the operator
is in the program, the mode key need only be pressed
once or twice to return to the main menu.
4. After correcting system problems, clear trouble codes
using the trouble codes menu of the scanalyzer.
Clearing Codes
Unlike the check engine lamp diagnostics, note that the
Scanalyzer does allow the operator to clear trouble codes
from memory as well as differentiate between current and
historic codes.
Trouble codes cannot be cleared while the engine is running.
Turn the engine off by setting handlebar stop switch to the
OFF position, but leaving the ignition/light key switch ON.
Return the handlebar engine stop switch to the RUN position
and restart motorcycle.
NOTE
For more detailed instructions, refer to the literature provided
with the Scanalyzer.
REMOVAL
1. Turn ignition/light key switch OFF. Set engine stop switch
to the OFF position.
2. Unplug Scanalyzer from data link connector. Install pro-
tective plug connector.
3. Attach data link connector to frame.
4. Road test vehicle and observe check engine lamp. Con-
firm proper operation without the reoccurrence of trouble
codes. See 4.4 CHECKING FOR TROUBLE
