Control system
TIP:
The actual APS output voltage may vary ac-
cording to environmental conditions.
3. Squeeze the throttle lever “1” to the fully
open position, and then check the voltage
difference between APS 1 and APS 2.
Measure the APS input voltage if out of
specification.
4. Squeeze the throttle lever “1” slowly and
check that the “APS full close switch” dis-
play changes from the “ON” to “OFF.”
5. Disconnect the APS coupler “a”.
6. Supply power to the ECM, and then mea-
sure the input voltage at the APS coupler
terminals (wire harness end). Check the
APS circuit for continuity if out of specifica-
tion.
7. Connect the APS coupler.

1. Disconnect the APS coupler “a” and ECM
couplers “b” and “c”.
