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.
IMPORTANT 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.

form 50 start and run cycles. To execute one run cycle:
