1.CHECK LAN SYSTEM. Inspect LAN system. Basic Diagnostic Procedure > PROCEDURE | | 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. | Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC B2283 VEHICLE SPEED SENSOR |
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- | Replace the keyless access CM. Keyless Access CM | Check the VDC. Basic Diagnostic Procedure > PROCEDURE |
