DTC PROCEDURE

Step Check Yes No
1 CHECK CURRENT DATA. 
  1. Start the engine.
  2. Read the value of «Battery temperature» using the Subaru Select Monitor.
    NOTE: For detailed operation procedures, refer to "Current Data Display For Engine". < Ref. to SUBARU SELECT MONITOR . >
Is the value of «Battery temperature » 100°C (212°F) or more? Go to step . Even if DTC is detected, 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.
2 CHECK HARNESS BETWEEN ECM AND BATTERY CURRENT & TEMPERATURE SENSOR CONNECTOR. 
  1. Turn the ignition switch to OFF.
  2. Disconnect the connector from ECM and battery current & temperature sensor.
  3. Measure the resistance between ECM and engine ground.

    Connector & terminal 

    (B134) No. 41 - Engine ground: 

Is the resistance 1 MΩ or more? Replace the battery current & temperature sensor. < Ref. to BATTERY CURRENT & TEMPERATURE SENSOR . > Repair the ground short circuit of harness between ECM and battery current & temperature sensor connector.
