BS: DTC P1700
—THROTTLE POSITION SENSOR CIRCUIT
MALFUNCTION FOR AUTOMATIC
TRANSMISSION (ATTH)—
DTC DETECTING CONDITION:
Two consecutive trips with fault
TROUBLE SYMPTOM:
Shift point too high or too low; engine brake not effected
in“3”range; excessive shift shock; excessive tight corner
“braking”
10BS1Check DTC P1700 on display.
Check throttle position sensor circuit.
CAUTION:
After repair or replacement of faulty parts, conduct
CLEAR MEMORY and INSPECTION MODES.

10BS1
CHECK DTC P1700 ON DISPLAY.
: Does the Subaru select monitor or OBD-II
general scan tool indicate DTC P1700?
: Check throttle position sensor circuit.
NOTE:
For the diagnostic procedure on throttle position sensor
circuit, refer to 3-2 [T7K0].

10BT1CHECK HARNESS BETWEEN TCM AND
CCM CONNECTOR.
1) Turn ignition switch to OFF.
2) Disconnect connectors from TCM and CCM.
3) Measure resistance of harness between TCM and CCM
connector.
: Connector & terminal
(B56) No. 3—(B94) No. 3:
Is the resistance less than 1Ω?
: Go to next step 4).
: Repair open circuit in harness between TCM and
CCM connector.

4) Measure resistance of harness between TCM and
chassis ground.
: Connector & terminal
(B56) No. 3—Chassis ground:
Is the resistance less than 10Ω?
: Repair short circuit in harness between TCM and
CCM connector.
: Go to step10BT2.

CHECK INPUT SIGNAL FOR TCM.
1) Connect connector to TCM and CCM.
2) Lift-up the vehicle or set the vehicle on free rollers.
CAUTION:
On AWD models, raise all wheels off ground.
3) Start the engine.
4) Cruise control main switch to ON.
5) TCS OFF switch to ON. (with TCS models only)
6) Move selector lever to“D”and slowly increase vehicle
speed to 50 km/h (31 MPH).
7) Cruise control set switch to ON.
8) Measure voltage between TCM and chassis ground.
: Connector & terminal
(B56) No. 3 (+)—Chassis ground ( ):
Is the voltage less than 1 V?
: Go to next.
: Check cruise control set circuit.

: Is there poor contact in TCM connector?
: Repair poor contact in TCM connector.
: Replace TCM.
