DTC PROCEDURE

Step	Check	Yes	No
1 CHECK CURRENT DATA. Using the Subaru Select Monitor, confirm the current data of drive motor control system, the value of «Drive Motor Temperature A Sensor Voltage». < Ref. to DRIVE MOTOR CONTROL SYSTEM , OPERATION, Read Current Data.>	Is the value 4.6 V 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). Turn the ignition switch to OFF. Disconnect the DMCM connector (R442, R443). Disconnect the drive motor assembly connector (B603). Using a tester, measure the resistance between terminals in the DMCM connector and between the terminals in the drive motor assembly connector. Connector & terminal DMCM side (R442) No. 3 - (R442) No. 1 - 22 (except No. 5): (R442) No. 3 - (R443) No. 1 - 26: (R442) No. 4 - (R442) No. 1 - 22 (except No. 5): (R442) No. 4 - (R443) No. 1 - 26: Drive motor side (B603) No. 18 - (B603) No. 1 - 19 (except No. 17): (B603) No. 19 - (B603) No. 1 - 19 (except No. 17):	Does the resistance between either two points show 1 MΩ or more?	Go to step 3 .	Repair the short circuit to power in harness between DMCM connector and drive motor assembly connector, or repair the intermediate connector.
3 CHECK DRIVE MOTOR. Using a tester, measure the resistance between terminals in the drive motor assembly connector. Connector & terminal (T32) No. 18 - (T32) No. 1 - 19 (except No. 17): (T32) No. 19 - (T32) No. 1 - 19 (except No. 17):	Does the resistance between either two points show 1 MΩ or more?	Replace DMCM. < Ref. to appropriate DRIVE MOTOR CONTROL MODULE in Continuously Variable Transmission TH58A article.>	Replace the drive motor assembly. < Ref. to appropriate DRIVE MOTOR ASSEMBLY in Continuously Variable Transmission TH58A article.>
