CAUTION:

Use CHECK BOARD when measuring the TCM terminal voltage and resistance.
After servicing or replacing faulty parts, perform the last step of the basic diagnostic procedure. Ref. to TRANSMISSION (DIAGNOSTICS)>BASIC DIAGNOSTIC PROCEDURE .

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 - 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 - 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 - 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)>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. Read the data of [ATF Temp.] using Subaru Select Monitor. Ref. to TRANSMISSION (DIAGNOSTICS)>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)>TRANSMISSION CONTROL MODULE (TCM) .
