Case IH AFX8010 Repair Manual page 1469

A. If the resistance is lower than the previously measured resistance, there is a short in the harness
between connector X011 and connector X016 wires 878 white and 877 blue. Locate the short and
repair. Continue with Step 7.
B. If the resistance is the same as previously measured, reattach all connectors and continue with Step 5.
5. Key on. Disconnect connector X450. Use a multimeter to check for voltage at connector X450 pin B (harness
end). There should be no voltage on this wire.
A. If there is no voltage present on the wire, continue with Step 7.
B. If there is voltage present on the wire, continue with Step 6.
NOTE: The high voltage source may not be present as it may not be currently powered up. If the fault code
typically appears when operating another circuit, activate that circuit while performing this check.
6. Key on. Disconnect connector X011. Use a multimeter to check for voltage at connector X011 pin 13 (module
side of connector). There should be no voltage on this wire.
A. If there is no voltage on the wire, the short to voltage is between connector X450 and connector X011
wire 877 blue. Locate the short and repair. Continue with Step 7.
B. If there is voltage on the wire, the short to voltage is between connector X011 and connector X016 wire
877 blue. Locate the short and repair. Continue with Step 7.
NOTE: The high voltage source may not be present as it may not be currently powered up. If the fault code
typically appears when operating another circuit, activate that circuit while performing this check.
7.
The sense resistor in the module for the Beater/Chopper Current Sense circuit is easily damaged as a result of
excessive current draw or a short to high voltage. After locating the source of the problem and correcting, the
module must be checked for damage.
Disconnect connector X011. Use a multimeter to check resistance between connector X011 pin 13 and
chassis ground. There should be less than 1 ohms resistance.
A. If there is infinite resistance, the sense resistor in the CCM2 module has failed. Replace the module.
B. If the resistance is correct, the sense resistor in the CCM2 module is okay, and the circuit should
function correctly. Continue with Step 8.
8. Operate the combine while monitoring the Beater/Chopper Current Sense circuit current on the Universal
Display Plus "DIAG" screen.
A. If no high out of range current readings are seen, erase the error code and continue operation.
