   *1	Battery	*2	Ammeter
   *a	Component without harness connected (Transmission Revolution Sensor)	*b	Magnet
   *c	5 mm (0.197 in.)	-	-

3. Wave a magnet left and right 5 mm (0.197 in.) or less from the tip of the transmission revolution sensor to output a high/low signal while measuring the current.
   NOTE:

   Make sure to wave the magnet during the inspection. The current will not change unless the magnet is moved as shown in the illustration.

4. Measure the current according to the value(s) in the table below.

   Standard Current

   Tester Connection	Condition	Specified Condition
   1 (PS-) - 2 (PS+)	Low signal (Move magnet closer)	6 mA
   1 (PS-) - 2 (PS+)	High signal (Move magnet away)	14 mA
