AUDIO AND VISUAL SYSTEM(for 8 Inch Display) Speaker Circuit

DESCRIPTION

for Separate Type Amplifier:

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 Built-in Type Amplifier:

If there is a short in a speaker circuit, the radio 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 receiver assembly, DCM (telematics transceiver)* or speakers.

CAUTION / NOTICE / HINT

Note

When replacing the DCM (telematics transceiver), make sure to replace it with a new one (w/ Telematics Transceiver).

Tech Tips

Depending on the parts that are replaced during vehicle inspection or maintenance, performing initialization, registration or calibration may be needed. Refer to Precaution for Audio and Visual System.
