1.CHECK LAN SYSTEM.

Inspect LAN system. Basic Diagnostic Procedure > PROCEDURE

Is LAN system normal-

Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC B2283 VEHICLE SPEED SENSOR

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-

Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC B2283 VEHICLE SPEED SENSOR

Check the VDC. Basic Diagnostic Procedure > PROCEDURE

3.CHECK CURRENT DATA.

Check the current data display of «Keyless access with push button start» using Subaru Select Monitor. Read Current Data

«Vehicle speed signal»

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

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.

4.CHECK HARNESS (OPEN CIRCUIT).

1) Disconnect the keyless access CM connector.

2) Disconnect the VDC CM connector.

3) Using a tester, measure the resistance between the keyless access CM connector and VDC CM connector.

Connector & terminal

(i241) No. 32 — (B310) No. 24:

Is the resistance less than 1 --

Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC B2283 VEHICLE SPEED SENSOR

Repair or replace the open circuit of harness.

5.CHECK HARNESS (OPEN CIRCUIT).

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

Connector & terminal

(i241) No. 32 — Chassis ground:

Is the resistance 30 k- or more-

Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC B2283 VEHICLE SPEED SENSOR

Repair or replace the short circuit of the harness.

6.CHECK KEYLESS ACCESS CM.

1) Connect each connector.

2) Using the Subaru Select Monitor, measure the waveform between the terminals of keyless access CM.

Connector & terminal

(i241) No. 32 — Chassis ground:

Is 3.54 Hz displayed when the vehicle is driven at approx. 5 km/h- Or does the value change from 3.54 Hz when the vehicle stops-
