DTC PROCEDURE

Step	Check	Yes	No
1 CHECK CURRENT DATA. Start the engine. Using the Subaru Select Monitor, confirm the current data of hybrid powertrain control system, the value of «12V Auxiliary Battery Temperature». < Ref. to HYBRID POWERTRAIN CONTROL SYSTEM , OPERATION, Read Current Data.>	Is the value 100°C (212°F) or more?	Go to step 2 .	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 (SHORT TO GROUND). Turn the ignition switch to OFF. Disconnect the ECM connector and battery temperature sensor connector. Using a tester, measure the resistance between the ECM connector and chassis ground. Connector & terminal (B137) No. 24 - Chassis ground:	Is the resistance 1 MΩ or more?	Replace the battery temperature sensor. < Ref. to BATTERY TEMPERATURE SENSOR .>	Repair the short circuit to ground in the harness between the ECM connector and battery temperature sensor connector.
