STEERING SWITCH SIGNAL B CIRCUIT
DescriptionINFOID:0000000003765941
Transmits the steering switch signal to AV control unit.
Diagnosis ProcedureINFOID:0000000003765942
1.CHECK STEERING SWITCH SIGNAL B CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect AV control unit connector and spiral cable connector.
3. Check continuity between AV control unit harness connector and spiral cable harness connector.
4. Check continuity between AV control unit harness connector and ground.
Is inspection result normal?
YES >> GO TO 2.
NO >> Repair harness or connector.
2.CHECK SPIRAL CABLE
Check spiral cable.
Is inspection result normal?
YES >> GO TO 3.
NO >> Replace spiral cable.
3.CHECK AV CONTROL UNIT VOLTAGE
1. Connect AV control unit connector and spiral cable connector.
2. Turn ignition switch ON.
3. Check voltage between AV control unit harness connector.
Is inspection result normal?
YES >> GO TO 4.
NO >> Replace AV control unit.
4.CHECK STEERING SWITCH
1. Turn ignition switch OFF.
2. Check steering switch. Refer to AV-492, "
Component Inspection".
Is inspection result normal?
YES >> INSPECTION END
NO >> Replace steering switch.
