THEFT DETERRENT / KEYLESS ENTRY: SMART KEY SYSTEM (for Entry Function, HV Model): PROBLEM SYMPTOMS TABLE; 2019 - 2024 MY RAV4 HV [02/2019

PROBLEM SYMPTOMS TABLE

HINT:

If a problem occurs in certain locations or at certain times of day, check for the possibility of wave interference.
When the electrical key transmitter sub-assembly is brought near a door control receiver (RF band), door outside handle assembly (LF band), indoor electrical key antenna (LF band) or any of the electrical key antennas (LF band), the possibility of wave interference decreases. By doing this, whether wave interference is causing the problem can be checked.
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.
Inspect the fuses and relays related to this system before inspecting the suspected areas below.
