Transmission Control Systems

1. CHECK SIGNAL VOLTAGE OUTPUT EMITTED FROM TCU.
a. Install spare fuse on FWD connector and set in FWD mode.
b. Turn ignition switch ON (with engine OFF).
c. Move selector lever to "D".
d. Measure voltage output emitted from TCU (with accelerator pedal released).

Connector & Terminal/Specified value
(B33) No.3 - No. 10/8-14V

e. Turn ignition switch OFF.
f. Remove spare fuse from FWD switch.
g. Turn ignition switch ON (with engine OFF).
h. Move selector lever to "D."
i. Measure voltage output emitted from TCU (with accelerator pedal fully depressed).

Connector & Terminal/Specified value
(B33) No. 3 - No. 10/0.5 V, max

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

Connector & Terminal/Specified value
(B33) No. 3 - (B16) No. 11/0 ohms
(B33) No. 3 - Body/1 Mohm min.
(B33) No. 10 - (B16) No. 4/0 ohms
(B33) No. 10 - Body/1 M Ohms min.

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

Connector & Terminal/Specified value
(E19) No. 11 - No.4/9-15 ohm
