Transmission Control Systems

DTC 11 Duty Solenoid A Diagnostic Chart:

Duty Solenoid A Circuit:

1. MEASURE SIGNAL VOLTAGE OUTPUT EMITTED FROM TCM.
a. Warm up the engine and transmission.
b. Ignition switch ON (Engine OFF).
c. Move selector lever to "N".
d. While opening and closing throttle valve, measure voltage between TCM connector and body.

Specified value
(B68) No. 8 - No. 10
1.5 - 3.0 V (Throttle is fully closed.)
0.5 V, max. (Throttle is fully open.)
(B68) No. 7 - No. 10
5 - 14 V (Throttle is fully closed.)
0.5 V, max.(Throttle is fully open.)

Transmission Control Unit:

2. CHECK HARNESSES BETWEEN TCM AND DUTY SOLENOID A AND BETWEEN TCM AND RESISTOR.
a. Disconnect connector from TCM.
b. Disconnect connector from transmission.
c. Disconnect connector from resistor.
d. Measure resistance between TCM connector and transmission and between TCM connector and body.

Specified value:
(B68) No. 8 - (B14) No. 7: 0 ohms
(B68) No. 8 - Body: 1 M Ohms min.

e. Measure resistance between TCM connector and resistor connector and between TCM connector and body.

Specified value:
(B68) No. 7 - (F25) No. 1: 0 ohms
(B68) No. 7 - Body: 1 M Ohms min.

3. CHECK DUTY SOLENOID A's GROUND LINE.
a. Disconnect connector from transmission.
b. Measure resistance between transmission connector receptacle (on transmission) and transmission case.

Specified value (T2) No. 4 - Transmission: 1 ohm max.

4. CHECK RESISTOR.
a. Disconnect connector from resistor.
b. Measure resistance between resistor terminals.

Specified resistance: 9 - 15 ohms

5. CHECK DUTY SOLENOID A
a. Disconnect connector from transmission.
b. Measure resistance between transmission connector receptacle (on transmission) terminals.

Specified value (T2) No. 7 - No. 4: 1.5 - 4.5 ohms
