New Holland CX720 Repair Manual page 2417

A. If no continuity is found the short to ground is in the harness between connector X023 pin 3 and connector
X094 pin B wire 715 grey. Locate the short and repair.
B. If continuity is found, the short to ground is in the harness between connector X023 pin 3 and connector
X017 pins J3-19 and 20 on one of the following wires :
Wire 715 grey, connector X023 pin 3 to harness splice
Wire 526 grey, harness splice to connector X017 pin J3-19
Wire 527 grey, harness splice to connector X017 pin J3-20
Visually inspect the harnesses for damage, bent or dislocated pins, corroded terminals or broken wires.
Locate the short to ground and repair.
6. Use a multimeter to check for continuity between connector X094 pin A and chassis ground.
A. If continuity is found, continue with step 7.
B. If no continuity is found, recheck the motor for continuity to ground at step 3.
7. Disconnect connector X023. Use a multimeter to check for continuity between connector X023 pin 4 and chassis
ground.
A. If no continuity is found, the short to ground is in the harness between connector X094 pin A and X023
pin 4 wire 716 white. Locate the short and repair.
B. If continuity is found, the short to ground is in the harness between connector X023 pin 4 and connector
X017 pins J3-39 and 40 on one of the following wires :
Wire 716 white, connector X023 pin 4 to harness splice
Wire 528 white, harness splice to connector X017 pin J3-39
Wire 529 white, harness splice to connector X017 pin J3-40
Visually inspect the harnesses for damage, bent or dislocated pins, corroded terminals or broken wires.
Locate the short to ground and repair.
8. Fault codes indicate circuit fault due to open circuit condition. Disconnect transmission shift motor connector
X094. Measure the resistance of the motor between terminals A and B. The correct resistance is 3 - 5 ohms .
A. The resistance is infinite, indicating an open condition in the motor. Replace the transmission shift motor.
B. The resistance is in specification. Continue with step 9.
9. Ensure that the batteries are connected using the battery key, and that fuse F25 is good. Use the multimeter to
check for continuity between connector X094 pin B and chassis ground.
A. If continuity is found, continue with step 11.
B. If no continuity is found, continue with step 10.
NOTE: The CCM module connects both sides of the circuit to ground when in neutral to "lock" the motor in
position, irregardless of key switch position, as long as it receives power through fuse F25. This ground path
may be used to test for an open circuit condition.
10. Disconnect inline connector X023. Use a multimeter to check for continuity between connector X023 pin 3 and
chassis ground.
A. If continuity is found the open circuit is in the harness between connector X023 pin 3 and connector X094
pin B . Locate the open and repair.
B. If no continuity is found, the open circuit is in the harness between connector X023 pin 3 and connector
X017 pins J3-19 and 20 on one of the following wires :
Wire 715 grey, connector X023 pin 3 to harness splice
Wire 526 grey, harness splice to connector X017 pin J3-19
Wire 527 grey, harness splice to connector X017 pin J3-20
Visually inspect the harnesses for damage, bent or dislocated pins, corroded terminals or broken wires.
Locate the open circuit and repair.
11. Use a multimeter to check for continuity between connector X094 pin A and chassis ground.
A. If no continuity is found, continue with step 12.
