AUDIO AND VISUAL SYSTEM(except Sedan Radio and Display Type) Speaker Circuit
| DTC Code | DTC Name |

| 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 or speakers.
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 or speakers.
