pin B and connector X098 pin C wire 423 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 X011 pin B and connector X016 pin J2-19 wire 423 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 J2-19 and chassis ground. Use a multimeter to check for
continuity between connector X098 pin C and chassis ground.
A. If continuity is found, continue with step 9.
B. If no continuity is found, continue with step 8.
8. Disconnect the gearbox harness from the main frame harness at connector X011. Use a multi-meter to check
for continuity between the harness end of connector X011 pin B and chassis ground.
