one of the circuits that measures the high resistance.Repair: A resistance measurement that is between 5 ohms and 5000 ohms could indicate that a circuit is not open but could contain a poor connection. A resistance measurement that is greater than 5000 ohms could indicate that a wire is either not connected or is open.Check each circuit individually in order to isolate the circuit that has the problem.Check the connectors in the circuit in order to determine if there is a connection problem. Verify that there is continuity of the sensor circuits between the ECM and the Inverter Cabinet connector CN1 / CX-C3 and then between this connector and the connector in the rear axle housing.The motor winding temperature sensor connection diagram at the beginning of this procedure shows all of the circuit connections that are in the Inverter Cabinet. For complete machine harness and connector information in the circuits between the cabinet connectors and the temperature sensor in the rear axle housing, refer to the complete machine electrical system schematic. If any type of damage to the wiring or connectors is found, repair or replace the wiring harness or the connector.STOPTest Step 5. CHECK THE TEMPERATURE SENSOR CIRCUITS FOR A SHORTThe key start switch and the battery disconnect switch remain in the OFF position.The harness connector for the motor 1 temperature sensor terminal block enclosure remains disconnected.The J1 harness connector for the Motor 1 remains disconnected.
At the connector in the rear axle housing, remove the jumper wire that was used in the last test step.
At the Motor 2 ECM, disconnect the J1 harness wiring connector from the ECM.
At the Motor 1 ECM harness connector J1, measure the resistance between the sensor positive (+) contact J1-10 (wire RTDM1-2P-BK) and all of the other circuit contacts that
