SATELLITE RADIO TUNER

SATELLITE RADIO TUNER : Description

INFOID:0000000001450748

Left and right channel audio signals are supplied from the satellite radio tuner to the AV control unit through
the sound signal circuits.

SATELLITE RADIO TUNER : Diagnosis Procedure

INFOID:0000000001450749

LEFT CHANNEL

1.

CHECK HARNESS

1.

Turn ignition switch OFF.

2.

Disconnect satellite radio tuner (factory installed) connector M41
and AV control unit connector M43.

3.

Check continuity between satellite radio tuner (factory installed)
connector M41 (A)  and AV control unit connector M43 (B).

4.

Check continuity between satellite radio tuner (factory installed) connector M41 (A) and ground.

Are continuity results as specified?

YES

>> GO TO 2

NO

>> Repair harness or connector.

2.

CHECK LEFT CHANNEL AUDIO SIGNAL

1.

Connect satellite radio tuner (factory installed) and AV control unit.

2.

Turn ignition switch ON.

3.

Check signal between satellite radio tuner (factory installed)
connector M41 terminals 21 and 22 with CONSULT-III or oscillo-
scope.

Are voltage readings as specified?

YES

>> Replace AV control unit. Refer to 

AV-266, "Removal and Installation"

.

NO

>> Replace satellite radio tuner. Refer to 

AV-276, "Removal and Installation"
