OBD0380
AU: DTC P0710
—TRANSMISSION FLUID TEMPERATURE
SENSOR CIRCUIT MALFUNCTION (ATF)—
DTC DETECTING CONDITION:

Two consecutive trips with fault
TROUBLE SYMPTOM:

No shift up to 4th speed (after engine warm-up)

No lock-up (after engine warm-up)

Excessive shift shock
10AU1Check DTC P0710 on display.
Check ATF temperature sensor circuit.

CHECK DTC P0710 ON DISPLAY.
: Does the Subaru select monitor or OBD-II
general scan tool indicate DTC P0710?
: Check ATF temperature sensor circuit.
NOTE:
For the diagnostic procedure on transmission fluid tem-
perature sensor circuit, refer to 3-2 [T7F0].
