   Except D		10 kΩ or higher
   2	2 - 3	Below 1 Ω
   Except 2		10 kΩ or higher
   L	2 - 8	Below 1 Ω
   Except L		10 kΩ or higher

NG: REPLACE PARK/NEUTRAL POSITION SWITCH ASSEMBLY 

OK : Go to Next Step 

1. Connect the park/neutral position switch connector.
2. Turn the ignition switch to the ON position, and measure the voltage according to the value(s) in the table below when the shift lever is moved to each position.

   Standard voltage 

   TESTER CONNECTION SPECIFIED CONDITION CHART
   
   

   Shift Position	Tester Connection	Specified Condition
   P and N	E3-16 (NSW) - Body ground	Below 1 V
   Except P and N	↑	10 to 14 V
   R	E5-11 (R) - Body ground	10 to 14 V*
   Except R	↑	Below 1 V
   D	E5-10 (D) - Body ground	10 to 14 V
   Except D	↑	Below 1 V
   2	E5-9 (2) - Body ground	10 to 14 V
   Except 2	↑	Below 1 V
   L	E5-8 (L) - Body ground	10 to 14 V
   Except L	↑	Below 1 V

   HINT:

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