Trouble Shooting
NOTE:
The remote keyless entry system is part of body control system. For additional information and remote keyless entry system trouble shooting, see BODY CONTROL SYSTEMS - LS400 article.
NOTE:
Trouble shooting is based on the assumption that basic power door lock functions are operating correctly. Also ensure anti-theft system operates normally, and check transmitter battery condition.
Verify customer complaint. Perform a visual inspection, checking for open fuses, disconnected or damaged wire harnesses and components. Repair or replace items as necessary and recheck. If no problems are found, diagnose by symptom. See SYMPTOM TESTS .
