CHECK HARNESS .
1. Turn the ignition switch to OFF.
2. Disconnect the TCM connector.
3. Turn the ignition switch to ON.
4. Measure the voltage between TCM connectors.
  Connector & terminal
  
  (T10) No. 6 (+) - (T10) No. 1 (-):
Is the voltage 5 V or more?

Yes : Repair the short circuit of harness.

No : Go to 2.
CHECK ATF TEMPERATURE SENSOR .
1. Turn the ignition switch to OFF.
2. Measure the resistance between TCM connector terminals.
  Connector & terminal
  
  (T10) No. 1 - (T10) No. 6:
Is the resistance 1 MΩ or more?

Yes : Repair the open circuit of transmission harness.

No : Go to 3.
CHECK ATF TEMPERATURE SENSOR .
1. Connect the connector to TCM.
2. Start the engine.
3. Warm up until the ATF temperature exceeds 50°C (122°F).
4. Turn the ignition switch to OFF.
5. Disconnect the TCM connector.
6. Measure the resistance between TCM connector terminals.
  Connector & terminal
  
  (T10) No. 1 - (T10) No. 6:
Is the resistance 650 - 990 Ω?

Yes : Go to 4.

No : Go to 6.
CHECK ATF TEMPERATURE SENSOR .
Measure the resistance between TCM connector terminals.

Connector & terminal

(T10) No. 1 - (T10) No. 6:

Does the resistance value increase gradually while the ATF temperature decreases?

Yes : Go to 5.

No : Replace the control valve body. Ref. to CONTINUOUSLY VARIABLE TRANSMISSION (TR580 CROSSTREK)>CONTROL VALVE BODY .
CHECK INPUT SIGNAL FOR TCM .
1. Connect the connector to TCM.
2. Turn the ignition switch to ON. (Do not start engine.)
3. Using the Subaru Select Monitor, read data of [ATF Temp.] in the [Data Monitor] of [Transmission]. Ref. to TRANSMISSION (DIAGNOSTICS) (CROSSTREK MODEL)>DATA MONITOR .
Does the ATF temperature gradually decrease?

Yes : Check for poor contact of the ATF temperature sensor and TCM connector harness, and repair the defective part.

No : Go to 6.
CHECK FOR POOR CONTACT .
Is there poor contact of ATF temperature sensor circuit?

Yes : Repair the poor contact.

No : Replace the TCM. Ref. to CONTINUOUSLY VARIABLE TRANSMISSION (TR580 CROSSTREK)>TRANSMISSION CONTROL MODULE (TCM) .
