Test Step 1. Inspect Electrical Connectors
and Wiring
A. Turn the keyswitch to the OFF position.
B. Thoroughly inspect ECM connector J1/P1,
machine interface connector J20/P20, and the
battery connections. Refer to Troubleshooting,
“Electrical Connectors - Inspect” for details.
C. Check the harness and wiring for corrosion,
abrasion, and pinch points from the throttle switch
to the ECM.
Expected Result:
All connectors, pins, and sockets should be
completely inserted and coupled. The harness and
wiring should be free of corrosion, abrasion, and
pinch points.
