B. If continuity is found, continue with step 6.
6. Disconnect connector X007. Use a multimeter to check for continuity between connector X007 pin 19 and
chassis ground.
A. If no continuity is found, the short to ground is in the harness between connector X032 pin 26 and con-
nector X007 pin 19 wire 711 gray. Locate the short and repair.
B. If continuity is found, the short to ground is in the harness between connector X007 pin 19 and connector
X017 pin J3-6 wire 711 gray. Locate the short and repair.
7. Use a multimeter to check for continuity between connector X308 pin A and chassis ground.
A. If continuity is found, continue with step 8.
B. If no continuity is found, recheck the motor for continuity to ground at step 3.
8. Disconnect connector X032. Use a multimeter to check for continuity between connector X032 pin 20 and
chassis ground.
A. If no continuity is found, the short to ground is in the harness between connector X308 pin A and X032
pin 20 . Locate the short and repair.
B. If continuity is found, continue with step 9.
9. Disconnect connector X007. Use a multimeter to check for continuity between connector X007 pin 3 and chassis
ground.
A. If no continuity is found, the short to ground is between connector X007 pin 3 and connector X017 pin
J3-8 wire 712 white. Locate the short and repair.
B. If continuity is found, the short to ground is in the harness between connector X032 pin 20 and connector
X007 pin 3 wire 712 white. Locate the short and repair.
10. Fault codes indicate circuit fault due to open circuit condition. Disconnect reel speed motor connector X308.
Measure the resistance of the motor between terminals A and B. The correct resistance is XX to XX ohms.
A. The resistance is infinite, indicating an open condition in the motor. Replace the reel speed motor.
B. The resistance is in specification. Continue with step 11.
11. Ensure that the batteries are connected using the battery key, and that fuse F23 is good. Use the multimeter to
check for continuity between connector X308 pin B and chassis ground.
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 motor 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 inline 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 harness between connector X032 pin 26 and connector X308
pin B . 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 harness between connector X032 pin 26 and connector
X007 pin 19 wire 711 gray. Locate the open and repair.
B. If no continuity is found, the open circuit is in the harness between connector X007 pin 19 and connector
X017 pin J3-6 wire 711 gray. Locate the open and repair.
