2. CHECK HARNESS/CONNECTOR BETWEEN TCM AND VEHICLE SPEED SENSOR 1.
a. Disconnect connector from TCM.
b. Disconnect connector from transmission.

c. Measure resistance between TCM connector and transmission connector.

Specified value:
(B67) No. 12 - (B14) No. 16: 0 ohms
(B67) No. 12 - Body: 1 M Ohms min.
(B66) No. 20 - (B14) No. 9: 0 ohms
(B66) No. 20 - Body: 1 M Ohms min.

3. CHECK VEHICLE SPEED SENSOR 1.
a. Disconnect connector from transmission.
b. Measure resistance between transmission connector receptacle's terminals.

Specified value (T2) No 16 - No. 9: 450 - 650 ohms
