Case IH AFX8010 Repair Manual page 1955

A. If continuity is found, continue with Step 14.
B. If no continuity is found, continue with Step 12.
NOTE: The CCM module connects both sides of the circuit to ground when in neutral to "lock" the circuit in
position, irregardless of key switch position, as long as it receives power through fuse F23. This ground path
may be used to test for an open circuit condition.
12. Disconnect connector X032. Use a multimeter to check for continuity between connector X032 pin 26 and
chassis ground.
A. If continuity is found, the open circuit is in the header (HH) harness between connector X032 pin 26 and
connector X440 pin 2. Locate the open and repair.
B. If no continuity is found, continue with Step 13.
13. Disconnect connector X007. Use a multimeter to check for continuity between connector X007 pin 19 and
chassis ground.
A. If continuity is found, the open circuit is in the feeder (FE) harness between connector X032 pin 26and
connector X007 pin 19 wire 711 gray. Locate the open and repair.
B. If no continuity is found, the open circuit is in the front frame (FF) harness between connector X007 pin
19 and connector X017 pin J3-6 wire 711 gray. Locate the open and repair.
14. Use a multimeter to check for continuity between connector X440 pin 1 and chassis ground.
A.
If no continuity is found, continue with Step 15.
B. If continuity is found, recheck the motor for continuity at Step 10.
15. Disconnect connector X032. Use a multimeter to check for continuity between connector X032 pin 20 and
chassis ground.
A. If continuity is found, the open circuit is in the header (HH) harness between connector X440 pin 1
and X032 pin 20. Locate the open and repair.
B. If no continuity is found, continue with Step 16.
16. Disconnect connector X007. Use a multimeter to check for continuity between connector X007 pin 3 and
chassis ground.
A. If continuity is found, the open circuit is in the front frame (FF) harness between connector X007 pin 3
and connector X017 pin J3-8 wire 712 white. Locate the open and repair.
B.
If no continuity is found, the open circuit is in the feeder (FE) harness between connector X032 pin 20
and connector X007 pin 3 wire 712 white. Locate the open and repair.
17. If the circuit does not operate in either direction, and there are no error codes indicated, the supply power for
the circuit may not be present. Remove fuse F23 and inspect.
A. Fuse has failed. Go to Step 18.
B. Fuse is okay. Go to Step 19.
18.
If fuse has failed, replace the fuse.
A. If the fuse immediately fails, a short to ground exists on one of the two following wires:
- wire 025 red, from the fuse panel through connector X005 pin 1 to connector X016 pin J2-11 on
CCM2 module
- wire 028 red, from the fuse panel through connector X031 pin 4 to connector X017 pin J3-7 on CCM2
module. Visually inspect the harnesses for damage, bent or dislocated pins, corroded terminals or
broken wires. Locate the short to ground and repair.
B.
Fuse is okay. Go to Step 19.
19.
Test for 12V power at connector X017 pin J3-7 on the CCM2 module under the cab.
