M Crowell, the error F/dL can be caused by:
"A Door Lock Error occurs if the door cannot be locked. It will try to lock it 6 times
before displaying the error.
• Door Lock Mechanism broken or removed from the Door
• Check Door Lock/Switch Assembly
• Check the wire harness connections to the Door Lock/Switch Assembly and
Central Control Unit (CCU)
• Door Lock/Switch Assembly Failure" from the manual.
check all those things out, and you may have to replace the mechanism. Hope this helps, good luck.
