CHECK HARNESS .
CAUTION: Start work after ATF cools down.
1. Turn the ignition switch to OFF.
2. Disconnect the TCM connector.
3. Remove the transmission valve cover.
4. Disconnect the control valve body connector.
5. Measure the resistance between TCM connector and chassis ground.
  Connector & terminal
  
  (T10) No. 31 - Chassis ground:
Is the resistance 1 MΩ or more?

Yes : Go to 2.

No : Repair the short circuit of harness.
CHECK OIL PUMP ON/OFF SOLENOID .
1. Connect the connector for control valve body.
2. Measure the resistance between TCM connector and transmission body.
  Connector & terminal
  
  (T10) No. 31 - Transmission body:
Is the resistance approximately 12.5 - 19.5 Ω? (When cold)

Yes : Check for poor contact of connector, and if no fault is found, replace the TCM. Ref. to CONTINUOUSLY VARIABLE TRANSMISSION (TR580 CROSSTREK)>TRANSMISSION CONTROL MODULE (TCM) .

No : Go to 3.
CHECK HARNESS INSIDE TRANSMISSION .
Check for the harness pinch, damage.

Is the check result OK?

Yes : Replace the control valve body. Ref. to CONTINUOUSLY VARIABLE TRANSMISSION (TR580 CROSSTREK)>CONTROL VALVE BODY .

No : Replace the transmission harness.
