ELECTRONIC THROTTLE CONTROL – ETC
– continued
The Select Test screen is displayed on the DDT. The ETC test can
be performed with the engine running or not. This test allows the
technician to instruct the ECM to open or close the throttle valve
(blade). If no engine rpm is selected the DDT is allowed to move the
throttle valve (blade) from closed to a full open postion. Testing with
engine rpm the valve (blade) will not move the full range.
Select Test:
1-ENGINE RPM
2-NO ENGINE RPM
NOTE: If the electronic throttle control on the engine does respond
to this test, then diagnose the wiring or sensors between the ECM, the
throttle control box at the helm or the ETC itself. Refer to the electrical
wiring diagram in the service manual if needed.
