| Title: THEFT DETERRENT / KEYLESS ENTRY: THEFT DETERRENT SYSTEM: PROBLEM SYMPTOMS TABLE (2008 LX570) | ||
PROBLEM SYMPTOMS TABLE
HINT:
- 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.
- Troubleshooting of the theft deterrent system is based on the premise that the door lock control system, the wireless door lock control system, the lighting system, the horn system, the engine immobiliser system and the smart access system with push-button start are operating normally. Check these systems first before troubleshooting the theft deterrent system.
