Case IH AFX8010 Repair Manual page 1263

A. Refer to the appropriate repair manual chapter for repair and adjustment of the transmission shift
assembly.
3. Fault codes indicate circuit fault due to short to ground. Disconnect the transmission shift motor connector
X094. Use a multimeter to check for continuity between the motor side of connector X094 pins A and B and
chassis ground. There should not be any continuity to ground.
A. If there is continuity to ground, there is a short to ground in the motor. Replace the transmission shift
motor.
B. If there is no continuity to ground, continue with step 4.
4. Disconnect the batteries by removing the negative battery cables. Use a multimeter to check for continuity
between the harness end of connector X094 pin B and chassis ground. There should not be any continuity
to ground.
A. If continuity is found, continue with step 5.
B. If no continuity is found, continue with step 6.
NOTE: The CCM module connects both sides of the circuit to ground when in neutral to "lock" the motor in
position. Power must be removed from the module prior to testing for short to ground condition on the motor
circuit to remove this ground path.
5. Disconnect connector X023. Use a multimeter to check for continuity between the front frame (FF) harness
end of connector X023 pin 3 and chassis ground. There should not be any continuity to ground.
A. If no continuity is found, there is a short to ground in the lower frame (LF) harness between connector
X023 pin 3 and connectorX094 pin B wire 715 grey. Locate the short and repair.
B. If continuity is found, there is a short to ground in the front frame (FF) harness between connector X023
pin 3 and connector X017 pins J3-19 and J3-20 on one of the following wires: wire 715 grey, connector
X023 pin 3 to FF harness splice, wire 526 grey, harness splice to connector X017 pin J3-19, and wire
527 grey, harness splice to connector X017 pin J3-20. Locate the short and repair.
6. Disconnect connector X094. Use a multimeter to check for continuity between the harness end of connector
X094 pin A and chassis ground. There should not be any continuity to 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 the front frame (FF) harness
end of connector X023 pin 4 and chassis ground. There should not be any continuity to ground.
A. If no continuity is found, there is a short to ground in the lower frame (LF) harness between connector
X023 pin 4 and connectorX094 pin A wire 716 white. Locate the short and repair.
B. If continuity is found, there is a short to ground in the front frame (FF) harness between connector X023
pin 4 and connector X017 pins J3-39 and J3-40 on one of the following wires: wire 716 white, connector
X023 pin 4 to FF harness splice, wire 528 white, harness splice to connector X017 pin J3-39, and wire
529 white, harness splice to connector X017 pin J3-40. Locate the short and repair.
8. Fault codes indicate circuit failure due to open circuit condition. Disconnect the transmission shift motor
connector X094. Use a multimeter to measure the resistance between the motor end of connector X094 pins
A and B. The correct resistance is 28 - 33 ohms.
A. If the resistance is infinite, there is an open condition in the motor. Replace the transmission shift motor.
B.
If the resistance is within specification, continue with step 9.
9.
Ensure that the battery cables are securely connected, and that fuse F-25 is good. Use a multimeter to
check for continuity between the harness end of connector X094 pin B and chassis ground. There should
be continuity to ground.
A. If continuity is found, continue with step 11.
B. If no continuity is found, continue with step 10.
