Troubleshooting Procedure (continued)
Step Actions and Questions
22 Check the connectors of the Feed
Solenoid for connection.
Check the connections between the
MCU Board and Feed Solenoid.
Are P/J23 and P/J231 connected
correctly?
23 Check the Left Side Harness Assy for
continuity.
Disconnect J23 from the MCU Board.
Disconnect P231 from the Feed
Solenoid.
Is each cable of J23 <=> P231
continuous?
24 Check the power to the Feed Solenoid.
Disconnect J23 from the MCU Board.
Is the voltage across P23-1 <=> ground
on the MCU Board, about +24 VDC
when the Interlock Switch (Interlock
Harness Assy) is pushed?
25 Check the Feed Solenoid for resistance.
Disconnect P/J231 of the Feed
Solenoid.
Is the resistance across J231-1 and
J231-2 about 96 ohm?
26 Check the connections between the
MCU Board and Registration Sensor.
Are P/J23 and P/J232 connected
correctly?
27 Check the Left Side Harness Assy for
continuity.
Disconnect J23 from the MCU Board.
Disconnect J232 from the Registration
Sensor.
Is each cable of J23 <=> J232
continuous?
28 Check the power to the Registration
Sensor.
Disconnect J23 from the MCU Board.
Is the voltage across P23-3 <=> ground
on the MCU Board, about +3.3 VDC?
