- Clear the diagnostic trouble code.
- Implementation of driving cycle:

hed off and temperature sensor unplugged
from the EDU so that the radiator fan runs

( 140° F) or for at least 1 minute if this tempera-
ture is reached earlier.

and then let the engine run at idling speed for
30 seconds. Do this twice again.
