Transmission Control Systems

1. MEASURE SIGNAL VOLTAGE INPUT OF TCU.
a. Turn ignition switch ON (with engine OFF).
b. Move select lever to "N" and slowly move vehicle by pushing it.
c. While vehicle is slowly moving, measure signal volt. age input of TCU.

Connector & Terminal/Specified value
(B46) No. 11 - (B46) No.20/0 or 5V

2. CHECK HARNESS/CONNECTOR BETWEEN TCU AND VEHICLE SPEED SENSOR 2
a. Disconnect connector from TCU.
b. Disconnect connector from rear of combination meter.
c. Measure resistance between TCU connector and combination meter cable connector.

Connector & Terminal/Specified value
(B46) No. 11 - (i16) No.11/ 0 ohms
(B46) No. 1 1- Body /1 Mohm min.

3. CHECK VEHICLE SPEED SENSOR 2.
a. Remove combination meter from instrument panel.
b. Rotate combination meter with a screwdriver inserted into - rear of combination meter at cable location.
c. Check that voltage across combination meter cable connector terminals changes (from 0 to 5) volts four times per rotation.

Connector & Terminal/Specified value
(i16) No.11 - (i16) No. 7/ 0 or 5 V
