2. Measure the resistance according to the value(s) in the table below.

   Resistance

   Tester connection (Symbols)	Condition	Specified condition
   D14-1 (GND) - Body ground	Always	Below 1 Ω
   D14-2 (SGND) - Body ground	Always	Below 1 Ω

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step
