HOW TO PROCEED WITH TROUBLESHOOTING

HINT:

Troubleshooting of the wireless door lock control system is based on the premise that the power door

lock system is operating normally. Therefore, before troubleshooting the wireless door lock control sys-

tem, first make certain that the the power door lock system is operating normally.

Use this procedure to troubleshoot the wireless door lock control system.
