2. Turn the ignition switch to ON.
3. Measure the voltage according to the value(s) in the table below.

   Standard Voltage

   Tester Connection	Switch Condition	Specified Condition
   B5-1 (RB) - Body ground	Ignition switch ON	11 to 14 V

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. Turn the ignition switch to ON.

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

   Standard Voltage

   Tester Connection	Switch Condition	Specified Condition
   B5-4 (B) - Body ground	Ignition switch ON	11 to 14 V

NG → See step   5 

OK: Go to next step 

1. Disconnect the park/neutral position switch connector.

2. Measure the resistance according to the value(s) in the table below when the shift lever is moved to each position.

   Standard Resistance

   Tester Connection	Shift Lever Position	Specified Condition
   4 - 9	P or N	Below 1 Ω
   	Except P and N	10 Ω or higher
   1 - 2	R	Below 1 Ω
   	Except R	10 Ω or higher
   1 - 7	D, S, "+" or "-"	Below 1 Ω
   	Except D, S, "+" and "-"	10 Ω or higher

NG → See step   7 

OK: Go to next step 

1. Connect the park/neutral position switch connector.

2. Disconnect the TCM connectors.
3. Turn the ignition switch to ON, 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	Shift Lever Position	Specified Condition
   B52-15 (R) - Body ground	R	11 to 14 V*
   	Except R	Below 1 V
   B52-16 (D) - Body ground	D, S, "+" or "-"	11 to 14 V
   	Except D, S, "+" and "-"	Below 1 V

   HINT: 

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

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK → See step   6 

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

   Standard Resistance (Check for Open)

   Tester Connection	Condition	Specified Condition
   B5-4 (B) - B52-11 (NSW)	Always	Below 1 Ω

   Standard Resistance (Check for Short)

   Tester Connection	Condition	Specified Condition
   B5-4 (B) or B52-11 (NSW) - Body ground	Always	10 kΩ or higher

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK → See step   6
