Key switch ON. Operate the covers motor using the InfoView diagnostic screen. Use multimeter to measure the
voltage between connector X289 pin B and chassis ground.
A.
If 12 volts is not read continue with Step 24.
B.
If 12 volts is read, recheck the motor for continuity at Step 20. Erase the fault codes and continue oper-
ation.
24.
Disconnect connector X195. Key switch ON. Operate the covers motor using the InfoView diagnostic screen.
Use multimeter to measure the voltage between connector X195 pin 3 and chassis ground.
A.
If 12 volts is read the open is between connector X289 and connector X195 wire 693 gray in the JP
harness. Locate the open and repair.
B.
If 12 volts is not read the open is between connector X195 and the next splice in wire 693 gray in the main
frame harness.
25.

28.
Both concave and covers do not operate in either direction. Fault code indicates an open circuit. Remove the
concave/covers relay K-16 from the relay base. Operate the concave/covers through the InfoView diagnostics
screen. Use a multimeter to measure the voltage between relay base K-16 terminal 1 and chassis ground.
A.

main frame harness.
B.
If 12 volts is not read continue with Step 29.
29.
Disconnect connector X004. Operate the concave/covers through the InfoView diagnostics screen. Use a mul-
timeter to measure the voltage between connector X004 pin 29 and chassis ground.
A.
If 12 volts is read the open is between connector X004 and relay base K-16 terminal 1. Locate the open
and repair.
B.
If 12 volts is not read the open is between connector X004 and CCM1 connector X019 J2-21 wire 523
white in main frame harness. Locate the open and repair.
30.
