2007 Buell Lightning: Fuel System 4-9
HOME
NOTE
If the lamp flashes at a rate faster than normal, then you are
observing the “Intermission” only, which means that no trou-
ble codes are present.
7. When examining trouble codes, write down all codes on
a piece of paper.
a. If trouble codes are present, see Table 4-7. Follow
the applicable flow charts for each code.
b. If trouble codes are NOT present, but starting or
driveability problems are evident, see charts under
4.8 INITIAL DIAGNOSTIC CHECK.
8. Turn the ignition/light key switch OFF.
9. Remove diagnostic test wire and install protective cover
over data link connector. Return data link to original posi-
tion.
NOTE
The engine may be started and run when the trouble codes
are received using a jumper wire on Pins 1 and 2 of the data
link connector. However, if the jumper wire is removed with
the engine running, the check engine lamp will continue to
flash trouble codes. To stop check engine lamp from flashing
codes, turn engine stop switch OFF.
CLEARING CODES
After correcting system problems, clear trouble codes. If the
Digital Technician (Part No. HD-44750) is not available, per-
form 50 start and run cycles. To execute one run cycle:
1. Start the vehicle.
2. Let it run for at least 30 seconds.
3. Turn the engine off.
