Exit Sensor (PL17.1.11)
Step Check Yes No
Possible causative parts:
• Exit Sensor (PL17.1.11)
• Exit Sensor Harness Assembly (PL17.1.18)
• Sensor Harness Assembly (PL17.1.23)
• MCU Board (PL18.1.13)
1 Check the Exit Sensor operation
Execute Input Output diagnostic test [071-104], and check
the Exit Sensor operation.
Does the Exit Sensor function normally?
Replace the MCU
Board.
Go to step 2.
2 Check the Exit Sensor connection
Check the connection between the Exit Sensor and the MCU
Board.
Are P/J155, P/J151, and P/J15 connected securely?
Go to step 3. Connect P/J155,
P/J151, and
P/J15 securely.
3 Check the continuity between the Exit Sensor and the relay
connector
Is each cable of P/J155<=>P/J151 continuous?
Go to step 4. Replace the Exit
Sensor Harness
Assembly.
4 Check the continuity between the relay connector and the
MCU Board
Is each cable of P/J151<=>P/J15 continuous?
Go to step 5. Replace the
Sensor Harness
Assembly.
5 Check the power to the Exit Sensor (+5 VDC)
Check if the voltage between the MCU Board ground and the
P/J15-1 pin is about +5 VDC.
Replace the Exit
Sensor.
Refer to “+5 VDC
Power FIP” on
page 2-223.
