For resistance measuring unplug connection with wiring harness but recon-
nect straight after completion of check and verify tight fit and engagement of
catch.
■ ATTENTION: If the throttle position potentiometer was removed from
carburetor for checking, then verification of the throttle posi-
tion by the communication program will be necessary. See
chapter 13.6.
If this aid is not available, a trial run has to be conducted.
See chapter 12.3.22. Engine operation is only allowed
for transfer to the nearest service place, where this check
has to be performed afterwards.
◆ NOTE:
Removal of the intermediate flange W is not necessary, it
would only increase fitting tolerances.
