| Speaker Circuit |
DESCRIPTION
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, telematics transceiver* or speakers.
*: w/ Manual (SOS) Switch
CAUTION / NOTICE / HINT
Depending on the parts that are replaced during vehicle inspection or maintenance, performing initialization, registration or calibration may be needed. Refer to Precaution for Navigation System.
