Transmission Control Systems

1. MEASURE SIGNAL VOLTAGE OUTPUT EMITTED FROM TCU.
a. Raise vehicle and support with safety stands. On AWD model, raise all wheels off ground.
b. Warm up the engine and transmission.
c. Move shift lever to "D" and slowly increase vehicle speed to 60 km/h (37 MPH). Measure voltage output emitted from TCU.

Connector & Terminal/Specified value
(B33) No. 5 - No. 10/8 - 14 V (when wheels are locked up)

d. Return the engine to idling speed. Move shift lever to "N" and measure voltage output from TCU.

Connector & Terminal/Specified value
(B33) No. 5 - No. 10/0.5 V, max.

2. CHECK HARNESS BETWEEN TCU AND DUTY SOLENOID B.
a. Disconnect connector from TCU.
b. Disconnect connector from transmission.
c. Measure resistance between TCU connector and transmission connector, and between TCU connector and body.

Connector & Terminal/Specified value
(B33) No. 5 - (B16) No. 6/0 ohm
(B33) No. 5 - Body /1 Mohm min

3. CHECK DUTY SOLENOID B'S GROUND LINE.
a. Disconnect connector from transmission.
b. Measure resistance between transmission connector receptacle and transmission case.

Connector & Terminal/Specified value
(E19) No. 4 - Transmission /1 ohm max.

4. CHECK DUTY SOLENOID B.
a. Disconnect connector from transmission.
b. Measure resistance between transmission connector receptacle's terminals.

Connector & Terminal/Specified value
(E19) No. 6-No.4/9-15ohm
