B.
If continuity is found, the short to ground is in the front frame (FF) harness between connector X023 pin 1
and connector X020 pins J3-19 and 20 on one of the following wires :
Wire 707 gray, connector X023 pin 1 to harness splice
Wire 705 gray, harness splice to connector X020 pin J3-19
Wire 706 gray, harness splice to connector X020 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 X088 pin D 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 2 and chassis
ground.
A.
If no continuity is found, the short to ground is in the lower frame (LF) harness between connector X088
pin D and X023 pin 2 wire 710 white. Locate the short and repair.
B.
If continuity is found, the short to ground is in the front frame (FF) harness between connector X023 pin 2
and connector X020 pins J3-39 and 40 on one of the following wires :
Wire 710 white, connector X023 pin 2 to harness splice
Wire 708 white, harness splice to connector X020 pin J3-39
Wire 709 white, harness splice to connector X020 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 shoe leveling motor connector X088.
Measure the resistance of the motor between terminals D and E. The correct resistance is 1 - 5 ohms.
A.
The resistance is infinite, indicating an open condition in the motor. Replace the shoe leveling 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 F22 is good. Use the multimeter to
check for continuity between connector X088 pin E 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 F22. 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 1 and
chassis ground.
A.
If continuity is found, the open circuit is in the lower frame (LF) harness between connector X023 pin 1
and connector X088 pin E wire 707 white. Locate the open and repair.
B.
If no continuity is found, the open circuit is in the front frame (FF) harness between connector X023 pin 1
and connector X020 pins J3-19 and 20 on one of the following wires :
Wire 707 gray, connector X023 pin 1 to harness splice
Wire 705 gray, harness splice to connector X020 pin J3-19
Wire 706 gray, harness splice to connector X020 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 X088 pin D and chassis ground.
A.
If no continuity is found, continue with step 12.
B.
If continuity is found, recheck the motor for continuity at step 8.
