STEERING SWITCH

STEERING SWITCH

Description

INFOID:0000000004219589

When one of the steering wheel audio control switches is pushed, the resistance in the steering switch circuit

changes depending on which button is pushed.

Diagnosis Procedure

INFOID:0000000004219590

1.

CHECK HARNESS

1. Turn ignition switch OFF.

2. Disconnect AV control unit connector M46 and spiral cable connector M30.

3. Check continuity between AV control unit connector M46 (A) ter-

minals 25, 26, and 27 and spiral cable connector M30 (B) termi-

nals 24, 31, and 33. 

4. Check continuity between AV control unit connector M46 and

ground.

Are the continuity test results as specified?

YES

>> GO TO 2

NO

>> Repair harness.

2.

SPIRAL CABLE CHECK

1. Disconnect spiral cable connector M88.

2. Check continuity between spiral cable harness connector M30

(A) and M88 (B).

Are the continuity test results as specified?

YES

>> GO TO 3.

NO

>> Replace spiral cable. Refer to 

SRS-8, "Removal and Installation"

.

3.

CHECK STEERING SWITCH

Check steering switch. Refer to 

AV-229, "Component Inspection"

.

Does the steering switch pass inspection?

YES

>> Inspection End.

NO

>> Replace steering switch. Refer to 

AV-291, "Removal and Installation"

MICROPHONE SIGNAL CIRCUIT

MICROPHONE SIGNAL CIRCUIT

Description

INFOID:0000000004219592

Power is supplied to the microphone from the AV control unit. The microphone transmits voice signals to the

AV control unit.

Diagnosis Procedure

INFOID:0000000004219593

1.

CHECK CONTINUITY BETWEEN AV CONTROL UNIT AND MICROPHONE CIRCUIT

1. Turn ignition switch OFF.

2. Disconnect AV control unit connector M46 and microphone connector R7.

3. Check continuity between AV control unit harness connector

M46 (A) terminals 45, 46, 47 and microphone harness connec-

tor R7 (B) terminals 1, 2, 4.

4. Check continuity between AV control unit harness connector

M46 (A) terminals 45, 46, 47 and ground.

Is inspection result OK?

YES

>> GO TO 2

NO

>> Repair harness or connector.

2.

CHECK MICROPHONE VCC VOLTAGE 

1. Connect AV control unit connector.

2. Turn ignition switch ON.

3. Check voltage between AV control unit harness connector M46

terminals 46 and 47.

Is inspection result OK?

YES

>> GO TO 3

NO

>> Replace AV control unit. Refer to 

AV-278, "Removal and

Installation"

.

3.

CHECK MICROPHONE SIGNAL 

1. Connect microphone connector.

2. Check signal between AV control unit harness connector M46

terminals 45 and 47.

Is inspection result OK?

YES

>> Replace AV control unit. Refer to 

AV-278, "Removal and Installation"

.

45 - 1

: Continuity should exist.

47 - 2

: Continuity should exist.

46 - 4

: Continuity should exist.

45, 46, 47 - Ground

: Continuity should not exist.
