E3-18 (VC) - E3-34 (NE-)	Engine switch on (IG)	5 V

While turning the crankshaft pulley by hand, measure the voltage between each terminal. Check that the voltage changes between the Hi range and Lo range shown in the table below.

Standard Voltage

Tester Connection	Switch Condition	Specified Condition
E3-27 (NE+) - E3-34 (NE-)	Engine switch on (IG)	3.75 to 4.50 V (Voltage (Hi)) 0.50 to 1.25 V (Voltage (Lo))
