6. Disconnect the engine harness from the main frame harness at connector X010. Use a multimeter to check for
continuity between the harness end of connector X010 pin 8 and chassis ground.
A. If there is no continuity, there is a short to ground in the engine (EN) harness between connector X010 pin
8 and connector X202 pin C wire 420 yellow. Locate the short and repair.
B. If there is continuity to ground, there is a short to ground in the main frame (MF) harness between con-
nector X010 pin 8 and connector X016 pin J2-29 wire 420 yellow. Locate the short and repair.
7. Carefully disconnect the main frame harness from the CCM2 module at connector X016. Install a jumper wire
between the harness end of connector X016 pin J2-29 and chassis ground. Use a multimeter to check for

A. If continuity is found, continue with step 9.
B. If no continuity is found, continue with step 8.
8. Disconnect the engine harness from the main frame harness at connector X010. Use a multimeter to check for
continuity between the harness end of connector X010 pin 8 and chassis ground.
A. If there is continuity, there is an open circuit in the engine (EN) harness between connector X010 pin 8
and connector X202 pin C wire 420 yellow. Locate the open and repair.
B. If there is no continuity to ground, there is an open circuit in the main frame (MF) harness between con-
nector X010 pin 8 and connector X016 pin J2-29 wire 420 yellow. Locate the open and repair.
