DESCRIPTION
This circuit sends a signal to the stereo component amplifier assembly to mute noise. Because of that, the noise produced by changing the sound source ceases.
If there is an open in the circuit, noise can be heard from the speakers when changing the sound source.
If there is a short in the circuit, even though the stereo component amplifier assembly is functioning normally, no sound or only an extremely faint sound can be heard.

Cruise Main Indicator Light Circuit
DESCRIPTION
When the dynamic radar cruise control system is turned on using the cruise control
main switch (ON-OFF button), the cruise control indicator (vehicle-to-vehicle distance
control mode) illuminates. The ECM uses this and other indicators to indicate the
control condition (presence o ...
Antenna Coil Open / Short (B2784)
DESCRIPTION
When an open or short circuit is detected in the transponder key amplifier coil
built into the engine switch, the certification ECU (smart key ECU assembly) stores
this DTC. This DTC is also stored as a past DTC.
