DESCRIPTION
This circuit is necessary for the ASL (Auto Sound Leveliser) built into the radio receiver.
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.).

HINT: The vehicle speed sensor is functioning normally when the indication on the speedometer is normal.
2 INSPECT RADIO RECEIVER
*1: 6 Speaker without Rear Seat Entertainment System.
*2: 6 Speaker with Rear Seat Entertainment System
OK: Voltage pulses as shown in the illustration.
REPLACE RADIO RECEIVER
3 CHECK HARNESS AND CONNECTOR (COMBINATION METER - RADIO RECEIVER)
Standard resistance
*1: 6 Speaker without Rear Seat Entertainment System.
*2: 6 Speaker with Rear Seat Entertainment System.
4 CHECK HARNESS AND CONNECTOR (COMBINATION METER - RADIO RECEIVER)
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.
*1: 6 Speaker without Rear Seat Entertainment System.
*2: 6 Speaker with Rear Seat Entertainment System.
