Troubleshooting Procedure Table
Step Actions and Questions Yes No
1 Run the K Mode Solenoid test (DO-
a) on (page 4-44).
Does the solenoid opearate?
Go to step 2. Go to step 3.
2 Reseat the Feed Drive Assembly.
Does the error persist?
Go to step 6. Complete.
3 Check the solenoid connection.
Is P/J24 on the MCU Board secure?
Go to Step 4. Secure the
connection.
4 Check for +24 V at J24 on the MCU
Board.
Is +24 V available at J24-1 <=>
ground when the Interlock Switch is
closed?
Go to step 5. Replace the
MCU Board
(page 8-57).
5 Check the solenoid resistance.
Is the resistance across J24-1 and
J24-2 80 to 110 Ohms?
Replace the
MCU Board
(page 8-57).
Replace the
Feed Drive
Assembly
(page 8-37).
6 Check the solenoid connection.
Are P/J26 and P/J261 secure?
Go to step 7. Secure the
connections.
