2. With appropriate needle adapters on the meter leads,
connect the red tester lead to the orange wire; then
connect the black tester lead to the black wire.
3. Turn the ignition switch to the ON position.
4. The meter will typically show battery voltage.
5. Leave the black tester lead connected; then connect
the red tester lead to the pink/white wire.
6. Slowly move the vehicle forward or backward; the
meter must show 0 and battery voltage alternately.
To replace a speed sensor, use the following procedure.
