Keyless Access External Buzzer Does Not Beep

Using the Subaru Select Monitor, check the data of [Answerback Buzzer] of [Body Control].

Ref. to BODY CONTROL(DIAGNOSTICS)>Data Monitor .

Is the setting "ON"?

• Yes  : Go to 2. 
• No  : Change the setting to "ON". Ref. to BODY CONTROL(DIAGNOSTICS)>Customize .

Using the Subaru Select Monitor, perform the active test [Keyless Buzzer Output] of [Body Control]. Ref. to BODY CONTROL(DIAGNOSTICS)>Active Test .

Does the buzzer sound?

• Yes  : Go to 3. 
• No  : Go to  5.

1. Turn to IGN ON.
2. With all doors closed and the access key carried, touch the touch sensor (lock) on the driver's door handle.

Does the door lock?

• Yes  : Go to 4. 
• No  : Refer to "CANNOT LOCK WITH KEYLESS ACCESS FROM THE DRIVER'S DOOR" and perform inspection. Ref. to KEYLESS ACCESS WITH PUSH BUTTON START (DIAGNOSTICS)>Diagnostics with Phenomenon>INSPECTION>CANNOT LOCK WITH KEYLESS ACCESS FROM THE DRIVER'S DOOR .

1. Open the door glass.
2. Place the access key on the driver's seat, and close the door.
3. Touch the touch sensor (lock) on the driver's door handle.

Does the buzzer sound? (Lockout prevention alert)

• No  : Replace the keyless access CM. Ref. to SECURITY AND LOCKS>Keyless Access CM>REMOVAL .

1. Turn to IGN OFF.
2. Disconnect the connectors of the body integrated unit and keyless buzzer.
3. Measure the resistance between body integrated unit connector and keyless buzzer connector.

   Connector & terminal 

   (B280) No. 20 - (B164) No. 1:

Is the resistance less than 10 Ω?

• Yes  : Go to 6. 
• No  : Repair or replace the open circuit of harness.

Measure the resistance between keyless buzzer connector and chassis ground.

Connector & terminal 

(B164) No. 1 - Chassis ground:

Is the resistance 10 kΩ or more?

• Yes  : Go to 7. 
• No  : Repair or replace the short circuit of the harness.

Measure the resistance between keyless buzzer connector and chassis ground.

Connector & terminal 

(B164) No. 2 - Chassis ground:

Is the resistance less than 10 Ω?

• Yes  : Go to 8. 
• No  : Repair or replace the open circuit of harness.

1. Connect the connector of body integrated unit.
2. Using the Subaru Select Monitor, perform the active test [Keyless Buzzer Output] of [Body Control]. Ref. to BODY CONTROL(DIAGNOSTICS)>Active Test .
3. Measure the voltage between body integrated unit connector and chassis ground using an oscilloscope.

   Connector & terminal 

   (B280) No. 20 (+) - Chassis ground (-):

Is the frequency 2kHz, voltage 9 V or more?

• Yes  : Replace the keyless buzzer. Ref. to SECURITY AND LOCKS>Access Buzzer>REMOVAL .
• No  : Replace the body integrated unit. Ref. to SECURITY AND LOCKS>Body Integrated Unit .
