A.
There is infinite resistance. The sense resistor in the CCM1 module has failed. Replace the module.
B.
There is less than 1 ohms resistance, indicating the sense resistor in the CCM2 module is okay. There is
an open circuit in the main frame (MF) harness between connector X008 pin 13 and connector X019 pin
J2-10 wire 555 black. Locate the open and repair.
NOTE: The sense resistor in the module for the Header Tilt Current Sense circuit is easily damaged as a result
of excessive current draw or a short to high voltage.
7.
Turn the key switch to the ON position. Use the Universal Display Plus "DIAG" screen controls to manually
power the lateral tilt CCW valve. Use a multimeter to check for 12 volts between connector X021 pin J and
chassis ground.
A.
If 12 volts is not present, there is an open circuit in the front frame (FF) harness between connector
X021 pin J and connector X020 pin J3-1 wire 548 white. Locate the open and repair.
B.
If 12 volts is found, continue with Step 9.
8.
Visually inspect the harness and connectors for damage, bent or dislocated pins, corroded terminals or
broken wires.
A.
If no damage is found, erase the fault code and continue operation.
