Transmission Control Systems

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.











1. Check harnesses and connectors between Transmission Control Module (TCM) and Duty Solenoid A, and between Resistor.
a. Turn Ignition Switch to "OFF".
b. Disconnect connectors from TCM, Transmission and Resistor.





c. Measure resistance of harness connector between TCM and Transmission.
Connector & Terminal / Specified Resistance:
(B55) No. 8 - (B11) No. 7 / 1 Ohm, or less.





d. Measure resistance of harness connector between TCM and body to make sure that circuit does not short.
Connector & Terminal / Specified Resistance:
(B55) No. 8 - Body / 1 M-Ohms or more.





e. Measure resistance of harness connector between TCM and Resistor connector.
Connector & Terminal / Specified Resistance:
(B55) No. 7 - (B4) No. 1 / 1 Ohm, or less.





f. Measure resistance of harness connector between TCM and body to make sure that circuit does not short.
Connector & Terminal / Specified Resistance:
(B55) No. 7 - Body / 1 M-Ohms or more.

2. Check Duty Solenoid A, Ground Line.





Measure resistance between Transmission connector receptacle (on Transmission) and Transmission case.
Connector & Terminal / Specified Resistance:
(T4) No. 4 - Transmission / 1 Ohm, or less.

3. Check Resistor.





Measure resistance between Resistor terminals.
Specified Resistance:
(B4) No. 1 - No. 2 / 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.





a. Connect connectors to TCM, Transmission and Resistor.
b. Start and warm-up the Engine and Transmission.
c. Ignition switch "ON" (Engine "OFF").
d. Move Selector Lever to "N".
e. Measure voltage between TCM connector and body while opening and closing Throttle Position Sensor.
Connector & Terminal / Specified Resistance:
(B55) No. 8 - No. 10 / 1.5 - 4.0 Volts (Throttle is fully closed.)
(B55) No. 8 - No. 10 / 0.5 Volts, or less (Throttle is fully open.)
(B55) No. 7 - No. 10 / 5 - 14 Volts (Throttle is fully closed.)
(B55) No. 7 - No. 10 / 0.5 Volts, 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.)
