DESCRIPTION
This circuit is necessary for the ASL (Auto Sound Leveliser) built into the stereo component amplifier.
Speed signals are received from the combination meter and used for the ASL.
The ASL function automatically adjusts the sound data in order to enable hearing the clear audio sound even when vehicle noise increases (as vehicle noise increases, the volume is turned up etc.).

INSPECTION PROCEDURE
1 OPERATION OF SPEEDOMETER
OK: Actual vehicle speed and the speed indicated on the speedometer are the same.
HINT: The vehicle speed sensor is functioning normally when the indication on the speedometer is normal
2 INSPECT STEREO COMPONENT AMPLIFIER
OK: Voltage pulses as shown in the illustration.
REPLACE STEREO COMPONENT AMPLIFIER
3 CHECK HARNESS AND CONNECTOR (COMBINATION METER - STEREO COMPONENT AMPLIFIER)
Standard resistance
4 CHECK HARNESS AND CONNECTOR (COMBINATION METER - STEREO COMPONENT AMPLIFIER)
Standard resistance
HINT: If the resistance between terminal SPD and body ground is less than 10 kΩ, there may be a short in a wire harness, connector, or an ECU that is connected to the SPD signal wire
REPLACE COMBINATION METER
