Title: AUDIO / VIDEO: AUDIO AND VISUAL SYSTEM: Speaker Circuit; 2019 MY RAV4 RAV4 HV [11/2018 - 10/2019]

Speaker Circuit

DESCRIPTION

for 9 Speakers:

If there is a short in a speaker circuit, the stereo component amplifier assembly detects it and stops output to the speakers.

As a result, sound cannot be heard from the speakers even if there is no malfunction in the stereo component amplifier assembly, DCM (telematics transceiver) or speakers.

for 6 Speakers:

If there is a short in a speaker circuit, the radio and display receiver assembly detects it and stops output to the speakers.

As a result, sound cannot be heard from the speakers even if there is no malfunction in the radio and display receiver assembly, DCM (telematics transceiver)* or speakers.

  • *: w/ Manual (SOS) Switch

CAUTION / NOTICE / HINT

NOTICE:

  • When replacing the radio and display receiver assembly, always replace it with a new one. If a radio and display receiver assembly which was installed to another vehicle is used, the following may occur:
    • A communication malfunction DTC is stored.
    • The radio and display receiver assembly may not operate normally.
  • When replacing the DCM (telematics transceiver), make sure to replace it with a new one (w/ Manual [SOS] Switch).
  • Before replacing the DCM (telematics transceiver), refer to Registration.
