New Holland CX720 Repair Manual page 3907

A. If no voltage is found, continue with step 8.
B. If high (>5.2 V) voltage is found, continue with step 7.
7. Disconnect connector X023, and use a multimeter to test for voltage on the front frame (FF) harness end of
connector X023 pin 15. There should not be any voltage present.
A. If high (>5.2 V) voltage is found, there is a short to high voltage in the front frame (FF) harness between
connector X023 pin 15 and connector X020 pin J3-32 wire 721 yellow. Locate the short and repair.
B. If no voltage is found, there is a short to high voltage in the lower frame (LF) harness between connector
X088 pin C and connector X023 pin 15 wire 721 yellow. Locate the short and repair.
8. Disconnect connector X088, and use a multimeter to test for voltage on connector X088 pin A. There should
be 5 volts present.
A. If 5 volts is found, continue with step 11.
B. If high (>5.2 V) voltage is found, continue with step 9.
NOTE: This supply circuit is also used to supply power to the lateral float sensor, so a short to 12 volts anywhere
on the supply circuit will activate this error code.
9. Disconnect connector X023, and use a multimeter to test for voltage on connector X023 pin 17. There should
be 5 volts present.
A. If 5 volts is found, there is a short to high voltage in the lower frame (LF) harness between connector X088
pin A and connector X023 pin 17 wire 727 pink. Locate the short and repair.
B. If high (>5.2 V) voltage is found, continue with step 10.
10. Disconnect connector X007, and use a multimeter to test for voltage on the front frame (FF) harness end of
connector X007 pin 22.
A. If 5 volts is found, there is a short to high voltage in the feeder (FE) harness between connector X081 pin
A on the lateral float sensor R02 and connector X007 pin 22 wire 757 pink. Locate the short and repair.
B. If high (>5 V) voltage is found, there is a short to high voltage in the front frame (FF) harness between
connector X023 pin 17, connector X007 pin 22 and connector X020 pin J3-26 on one of the following
wires:
Wire 757 pink, connector X007 pin 22 to FF harness splice
Wire 727 pink, connector X023 pin 17 to FE harness splice
Wire 726 pink, FE harness splice to connector X020 pin J3-26
Locate the short and repair.
11. Operate the machine while monitoring InfoView monitor. If no high out of range readings are indicated, erase
the fault code and continue operation.
A. If the fault code immediately resets, determine which 12 volt circuit (such as the shoe leveling actuator)
was activated to cause the short.
