2. Disconnect the TCM connectors.
3. Turn the engine switch on (IG), 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
   B2-15 (R) - Body ground	R	11 to 14 V*
   	Except R	Below 1 V
   B2-16 (D) - Body ground	D, S, "+" or "-"	11 to 14 V
   	Except D, S, "+" and "-"	Below 1 V

   *a	Front view of wire harness connector (to TCM)

   HINT: 

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

Result: 

OK 

REPLACE TCM. Refer to  COMPONENTS [10/2014 - ] 

Result: 

NG 

REPAIR OR REPLACE HARNESS OR CONNECTOR 

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

   Standard Resistance (Check for Open)

   Tester Connection	Condition	Specified Condition
   B1-4 (B) - B2-11 (NSW)	Always	Below 1 Ω

   Standard Resistance (Check for Short)

   Tester Connection	Condition	Specified Condition
   B1-4 (B) or B2-11 (NSW) - Body ground and other terminals	Always	10 kΩ or higher

Result: 

OK 

REPLACE TCM. Refer to  COMPONENTS [10/2014 - ] 

Result: 

NG 

REPAIR OR REPLACE HARNESS OR CONNECTOR
