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