NOTICE:
w/ Door control Battery:
As the door control battery is installed between the vehicle battery and body ECU, first perform the inspections to confirm that there are no malfunctions in the power source circuit for the body ECU before performing this troubleshooting procedure (Click here).
HINT:
  1. Troubleshooting of the theft deterrent system is based on the premise that the power door lock control system and the wireless door lock control system are operating normally. Accordingly, before troubleshooting the theft deterrent system, first make certain that the power door lock control system and the wireless door lock control system are operating normally.
  2. Use the table below to help determine the cause of problem symptoms. If multiple suspected areas are listed, the potential causes of the symptoms are listed in order of probability in the "Suspected Area" column of the table. Check each symptom by checking the suspected areas in the order they are listed. Replace parts as necessary.
  3. Inspect the fuses and relays related to this system before inspecting the suspected areas below.
