   Tester Connection	Condition	Specified value
   Y1-1 (GND) - Body ground	Always	Below 1 Ω

2. Measure the voltage according to the value(s) in WIRE HARNESS (IG, GND) (VOLTAGE)  .

   Standard voltage 

   WIRE HARNESS (IG, GND) (VOLTAGE)
   
   

   Tester Connection	Condition	Specified value
   Y1-5 (IG) - Body ground	IG switch ON	10 to 14 V
