Step	Check	Yes	No
1 CHECK HARNESS. Turn the ignition switch to ON. Measure the voltage between TCM connectors. Connector & terminal (B54) No. 3 (+) - (B54) No. 16 (-):	Is the voltage 5 V or more?	Repair the short circuit of harness.	Go to step 2 .
2 CHECK HARNESS. Turn the ignition switch to OFF. Disconnect the TCM and transmission connectors. Measure the resistance between TCM connector and transmission connectors. Connector & terminal (B54) No. 3 - (B11) No. 16: (B54) No. 16 - (B11) No. 19:	Is the resistance less than 1 Ω?	Go to step 3 .	Repair the open circuit of harness.
3 CHECK ATF TEMPERATURE SENSOR. Turn the ignition switch to OFF. Connect the connectors to TCM and transmission. 3) Start the engine. Warm up until the ATF temperature exceeds 50°C (122°F). Turn the ignition switch to OFF. Disconnect the transmission connector. Measure the resistance between transmission connector terminals. Connector & terminal (T4) No. 16 - No. 19:	Is the resistance 730 - 1120 Ω?	Go to step 4 .	Go to step 6 .
4 CHECK ATF TEMPERATURE SENSOR. Measure the resistance between transmission connector terminals. Connector & terminal (T4) No. 16 - No. 19:	Does the resistance value increase gradually while the ATF temperature decreases?	Go to step 5 .	Replace the transmission harness.
5 CHECK INPUT SIGNAL FOR TCM. Connect the connector to transmission. Turn the ignition switch to ON. (Do not start engine.) Read the data of "ATF Temp." using Subaru Select Monitor.	Does the ATF temperature gradually decrease?	Check for poor contact of the ATF temperature sensor and transmission connector harness, and repair the fault location.	Go to step 6 .
6 CHECK FOR POOR CONTACT.	Is there poor contact of ATF temperature sensor circuit?	Repair the poor contact.	Check the TCM.
