TROUBLE CODE 11: DUTY SOLENOID A

DIAGNOSIS
Output signal circuit of duty solenoid A or resistor is open or shorted.

TROUBLE SYMPTOM
Excessive shift shock

WIRING DIAGRAM





1. CHECK HARNESSES AND CONNECTORS BETWEEN TCM AND DUTY SOLENOID A AND BETWEEN RESISTOR.
1) Turn ignition switch to OFF.
2) Disconnect connectors from TCM transmission and resistor.
3) Measure resistance of harness connector between TCM and transmission.





Connector & terminal / Specified resistance:
(B52) No. 8 - (B9) No. 7 / 1 ohms or less

4) Measure resistance of harness connector between TCM and body to make sure that circuit does not short.





Connector & terminal / Specified resistance:
(B52) No. 8 - Body / 1 Mohms or more

5) Measure resistance of harness connector between TCM and resistor connector.





Connector & terminal / Specified resistance:
(B52) No. 7 - (B1) No. 1 / 1 ohms, or less

6) Measure resistance of harness connector between TCM and body to make sure that circuit does not short.





Connector & terminal / Specified resistance:
(B52) No. 7 - Body / 1 Mohms or more

2. CHECK DUTY SOLENOID A's GROUND LINE.
Measure resistance between transmission connector receptacle (on transmission) and transmission case.





Connector & terminal / Specified resistance:
(T4) No. 4 - Transmission / 1 ohms, or less

3. CHECK RESISTOR.
Measure resistance between resistor terminals.





Specified resistance: (B1) No. 1 - No. 2 1 9 - 15 ohms

4. CHECK DUTY SOLENOID A.
Measure resistance between transmission connector receptacle (on transmission) terminals.





Connector & terminal / Specified resistance:
(T4) No. 7 - No. 4 / 1.5 - 4.5 ohms

5. CHECK OUTPUT SIGNAL EMITTED FROM TCM.
1) Connect connectors to TCM, transmission and resistor.
2) Start and warm-up the engine and transmission.
3) Ignition switch ON (Engine OFF).
4) Move selector lever to "N".
5) Measure voltage between TCM connector and body while opening and closing throttle position sensor.





Connector & terminal / Specified resistance:
(B52) No. 8 - No. 10 / 1.5 - 4.0 V (Throttle is fully closed.)
(B52) No. 8 - No. 10 /1 V, or less (Throttle is fully open.)
(B52) No. 7 - No. 10 / 5 - 14 V (Throttle is fully closed.)
(B52) No. 7 - No. 10 / 1 V, or less (Throttle is fully open.)

- Using Subaru select monitor:
(1) Connect connectors to TCM, transmission and resistor.
(2) Turn ignition switch to OFF.





(3) Connect the Subaru select monitor to data link connector.
(4) Turn ignition switch to ON and Subaru select monitor switch to ON.

(5) Start and warm-up the engine and transmission.
(6) Stop the engine and turn ignition switch to ON (Engine OFF).
(7) Move selector lever to "N".
(8) Read data on Subaru select monitor.
(9) Designate mode using function key.

Function mode: F11





SPECIFIED DATA:
- 100% (Throttle is fully closed.)
- 15% (Throttle is fully open.)
