Speaker Circuit |
DESCRIPTION
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.
Thus 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
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.
Thus sound cannot be heard from the speakers even if there is no malfunction in the stereo component amplifier assembly, DCM (telematics transceiver) or speakers.

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 may be 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 (w/ Manual [SOS] Switch).
