DTC B2282: Vehicle Speed Signal Correlation

DTC detecting condition: 

When any of the following is established with the ignition switch ON.

CAUTION:

Wiring diagram: 

  1. CHECK LAN SYSTEM. 

    Perform the diagnosis for LAN system. Refer to LAN SYSTEM (DIAGNOSTICS)>BASIC DIAGNOSTIC PROCEDURE>PROCEDURE .

    Is the check result OK?

    Yes:  Go to  2.

    No:  Perform the inspection according to the diagnosis for LAN system.

  2. CHECK COMBINATION METER. 

    Check that the speedometer is displayed normally.

    Is the meter display normal?

    Yes:  Go to  3.

    No:  Check the VDC. Refer to VEHICLE DYNAMICS CONTROL (VDC) (DIAGNOSTICS)>BASIC DIAGNOSTIC PROCEDURE>PROCEDURE .

  3. CHECK DATA MONITOR. 

    Using the Subaru Select Monitor, check the following items on «Data monitor» of «Keyless Access with Push Button Start». Refer to KEYLESS ACCESS WITH PUSH BUTTON START SYSTEM (DIAGNOSTICS)>DATA MONITOR .

    • «Vehicle speed signal»

    Is the display normal according to the parked state or driving state?

    Yes:  Even if DTC is displayed, the circuit has returned to a normal condition at this time. Reproduce the failure, and then perform the diagnosis again.

    NOTE: In this case, temporary poor contact of connector, temporary open or short circuit of harness may be the cause.

    No:  Go to  4.

  4. CHECK HARNESS (OPEN CIRCUIT). 
    1. Disconnect the keyless access control module connector.
    2. Disconnect the VDC control module connector.
    3. Using a tester, measure the resistance between the keyless access control module connector and VDC control module connector.

      Connector & terminal 

      Engine type FA with EyeSight 

      (B573) No. 7 - (B310) No. 22:

      Engine type FA without EyeSight 

      (B573) No. 7 - (B310) No. 5:

      Is the resistance less than 1 Ω?

      Yes:  Go to  5.

      No:  Repair or replace the open circuit of harness.

  5. CHECK HARNESS (GROUND SHORT CIRCUIT). 

    Using a tester, measure the resistance between the keyless access control module connector and chassis ground.

    Connector & terminal 

    (B573) No. 7 - Chassis ground:

    Is the resistance 30 kΩ or more?

    Yes:  Go to  6.

    No:  Repair or replace the short circuit of the harness.

  6. CHECK KEYLESS ACCESS control module. 
    1. Connect each connector.
    2. Using the Subaru Select Monitor, measure the waveform between the keyless access control module connector and chassis ground.

      Connector & terminal 

      (B573) No. 7 - Chassis ground:

      Is 3.54 Hz displayed when the vehicle is driven at approx. 5 km/h (3 MPH)? Or does the value change from 3.54 Hz when the vehicle stops?

      Yes:  Replace the keyless access control module. Refer to SECURITY AND LOCKS>KEYLESS ACCESS control module .

      No:  Check the VDC. Refer to VEHICLE DYNAMICS CONTROL (VDC) (DIAGNOSTICS)>BASIC DIAGNOSTIC PROCEDURE>PROCEDURE .
