TROUBLESHOOTING - KEYLESS ENTRY
4. What to do if the unlock response is slow when swiped with the Wristband
Key:
Possible Cause #1: Data Bus Failure Due to Wire Harness or Connector Problem
Actions To Take:
• Swipe each antenna and observe the Red LED.
-If that reader is NOT connected to the data bus, then the RED LED will continue to flash during the 6-second
solenoid timer.
• Verify the problem by unpluging the reader then repluging it, then observe the Mod QC test:
- The location code flashes twice:
- The data bus operation is tested and if the data bus is present, the Red LED flicker flashes for 10-seconds
(if the reader is at the curbside door, the flicker flash is a short burst).
- If there is NO flicker flash, the data bus is not active.
• A failure in the ID location pins in one of the readers will cause a “location conflict” on the data bus. For example,
the ground input on pin #7 has failed (no ground). The system “thinks” there are two Master Nodes present
which control the data bus traffic.
• Unplug each antenna and observe the QC test.The first test identifies the reader location. If it indicates two units
with same location ID, then you have found the problem. Fix the connector or wire harness.
Possible Cause #2: Internal Short in the Reader
Actions To Take:
• Verify there are no wire harness or connector problems.
• Verify all of the antenna-locations are correctly identified.
• Unplug the antenna reader from the wire harness and reconnect it.
• Observe the Mod QC Test:
1) The location code flashes twice
2) The data bus operation is tested and if the data bus is present, the Red LED flicker flashes 10-seconds (Note: If the reader
is at the Master Node, the flicker flash is a short burst). If the Red LED does NOT flicker flash, then the data bus cicuit
has failed.
• Replace the reader.
