   HINT: 

   *: The voltage will drop slightly due to the illumination of the back-up light.

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK → See step   6 

1. Disconnect the park/neutral position switch connector.
2. Disconnect the TCM connector.
3. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   B14-4 (B) - B31-11 (NSW)	Always	Below 1 Ω
   B14-4 (B) or B31-11 (NSW) - Body ground	Always	10 kΩ or higher

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK → See step   8
