5. Disconnect connector X008 behind the cab. Use a multimeter to check continuity between connector X008 pin
22 and chassis ground.
A. If there is continuity, there is an open in the main frame (MF) harness between connector X011 pin G and
connector X008 pin 22 wire 881 blue. Locate the open and repair.
B. If there is no continuity, continue with step 6.
6. Carefully disconnect connector X017 on the bottom of CCM2 module. Use a multimeter to check resistance
between connector X017 pin J3-35 and chassis ground. There should be approximately 50 ohms resistance.
A. There is infinite resistance. The sense resistor in the CCM2 module has failed. Replace the module.
B. The resistance is correct. The sense resistor in the CCM2 module is okay, and the circuit should function
correctly. Continue with step 7.
7. Erase fault code and continue operation.
A. If the fault immediately reoccurs, replace CCM2 with a known good controller.
