9-369 Rotary Lock Fail RAP
The Control Logic has detected that the Rotary Latch Solenoid failed to lock
Initial Actions
Refer to BSD 9.2 and BSD 9.15 for the following procedure.
Ensure that P/J412A and P/J418A on the IOT Drive PWB, P/J272 on the Rotary Latch Sole-
noid, and P/J116 on the Rotary Latch Sensor are connected before beginning this RAP.
Procedure
Enter dC330 009-237 Rotary Lock Mech Sensor. Press Start. The Display is (H)

Go to the +5 VDC (IOT) Wirenet and check the wires between P/J21 -1 on
the IOT LVPS and P/J418A -5 on the IOT Drive PWB. Go to the DC COM
(IOT) Wirenet and check the wires between P/J21-5 on the IOT LVPS and
P/J418A -3 on the IOT Drive PWB.
Go to Flag 5 on BSD 9.2 and check the wire for a short circuit to ground. Go to
the +5 VDC (IOT) Wirenet and check the wires between P/J116 -1 on the
Rotary Latch Sensor and P/J418A -5 on the IOT Drive PWB. Go to the DC
COM (IOT) Wirenet and check the wires between P/J116 -3 on the Rotary
Latch Sensor and P/J418A -3 on the IOT Drive PWB. If the wires are good,
replace the Rotary Latch Sensor ( PL 6.1 ).
Replace the IOT Drive PWB ( PL 9.2 ).
Enter dC330 009-018 Rotary Lock Mech Latch. Press Start. The Rotary Latch Sole-
noid Latches

Go to Flag 2 on BSD 9.2. Check the wires for an open circuit or a short circuit. If
the wires are good, replace the IOT Drive PWB ( PL 9.2 ). If the problem contin-
ues, replace the Rotary Latch Solenoid ( PL 6.1 ).
Go to Flag 2 on BSD 9.2 and check the wires for an open circuit. If the wires are
good, replace the Rotary Latch Solenoid ( PL 6.1 ).
Check the Rotary Latch Solenoid for binding or intermittent operation. If the Rotary Latch
Solenoid is good, replace the Rotary Latch Sensor (
PL 6.1 ). If the problem continues,
replace the Rotary Latch Solenoid( PL 6.1 ).
Replace the IOT Drive PWB ( PL 9.2 ).
