STEERING SWITCH SIGNAL B CIRCUIT (STEERING SWITCH TO TEL
ADAPTER UNIT)

Description

INFOID:0000000009949555

• Transmits the steering switch signal to TEL adapter unit.
• Transmits the steering switch signal to audio unit through TEL adapter unit.

Diagnosis Procedure

INFOID:0000000009949556

1.

CHECK STEERING SWITCH SIGNAL B (STEERING SWITCH TO TEL ADAPTER UNIT) CIRCUIT

1.

Turn ignition switch OFF.

2.

Disconnect TEL adapter unit connector and spiral cable connector. 

3.

Check continuity between TEL adapter unit harness connector and spiral cable harness connector.

4.

Check continuity between TEL adapter unit harness connector and ground.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair harness or connector.

2.

CHECK SPIRAL CABLE

Check spiral cable.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Replace spiral cable. Refer to 

SR-14, "Exploded View"

.

3.

CHECK TEL ADAPTER UNIT VOLTAGE

1.

Connect TEL adapter unit connector and spiral cable connector.

2.

Turn ignition switch ON.

3.

Check voltage between TEL adapter unit harness connector.

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Replace TEL adapter unit. Refer to 

AV-66, "Exploded View"

.

4.

CHECK STEERING SWITCH

1.

Turn ignition switch OFF.

2.

Check steering switch. Refer to 

AV-26, "Component Inspection"

.

Is the inspection result normal?

YES

>> INSPECTION END

NO

>> Replace steering switch. Refer to 

AV-68, "Exploded View"
