The Power Train Electric Drive System and the Accessory Power System will contain hazardous voltage levels during machine operation and for a period of time after machine shutdown.Do not remove any covers that will expose energized electrical components while the engine is operating. Do not remove any covers that will expose the energized electrical components while the components remain energized following an engine shutdown.Do not perform any type of electrical maintenance on the orange hazardous voltage conductors, the power train components or the accessory power system components while the engine is operating.Do not perform any type of electrical maintenance on the orange hazardous voltage conductors, the power train components or the accessory power system components while the components remain energized following an engine shutdown.Always perform the safe shutdown and de-energizing procedure before performing electrical service on the Power Train Electric Drive System or the Accessory Power System.Failure to follow these instructions could result in personal injury or death.
In order to avoid the build up of hazardous live voltages on the exposed surfaces, all grounding wires must be properly connected at all times during engine operation.Any disconnected grounding wires (including the grounding bond wires, the conductor shield wires, the power inverter grounding straps and the component housing grounding straps) must be properly reconnected before the engine is started.Failure to follow these instructions could result in personal injury or death.
Note: Always perform the procedure for shutdown and de-energizing before performing electrical service on the "Power Train Electric Drive System" or the "Accessory Power System". The procedure will verify that the voltage in the power train electrical system has been discharged to less than 50.0 VDC. Refer to the Specifications, Systems Operation, Troubleshooting, Testing and Adjusting, "Electrical Maintenance Guidelines" for the proper procedure.Note: A multimeter must be used to verify that there is little or no voltage present at the exposed conductors before any other action is taken. Manually measure the voltage in order to confirm the voltage to be at a low level (50.0 VDC or less).

Troubleshooting Test Steps Values Results
1. Inspect Electrical Connectors And Wiring
A. Perform a visual inspection of the wiring between the engine P1 connector and the EWPC. Look for these problems:
Harness damage that is caused by chafing
Harness damage that is caused by excessive heat
B. Inspect the P1 connector:
1. Look for moisture on the wiring and on the connector.
2. Pull on the wires that are associated with the data links. Verify that the wire is properly crimped to the terminal and that the terminal is properly inserted into the connector.
C. Inspect the EWPC connector.
1. Look for moisture on the wiring and on the connector.
Electrical Connectors And Wiring
Results: All connectors, pins, and sockets are coupled and/or inserted and the harness and wiring are free of corrosion, of abrasion or of pinch points. Proceed to Test Step 2.
Results: There is a problem with the wiring or with a connector.
Repair: Repair the connectors or wiring and/or replace the connectors or wiring. Ensure that all of the seals are properly in place and ensure that the connectors are coupled. Verify that the problem is resolved.
STOP
2. Check the CAN A Data Link Between the Engine ECM and the EWPC
Note: Always perform the procedure for shutdown
