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.
