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 Position	Specified Condition
   1 - 3 and 4 - 9	P	Below 1 Ω
   	Except P	10 kΩ or higher
   1 - 2	R	Below 1 Ω
   	Except R	10 kΩ or higher
   1 - 8 and 4 - 9	N	Below 1 Ω
   	Except N	10 kΩ or higher
   1 - 7	D, S, "+" and "-"	Below 1 Ω
   	Except D, S, "+" and "-"	10 kΩ or higher

NG → REPLACE PARK/NEUTRAL POSITION SWITCH ASSEMBLY 

OK: Go to next step 

1. Connect the transmission control switch connector of the shift lever assembly.

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

   Standard voltage

   Tester Connection	Switch Condition	Specified Condition
   B40-10 (STA) - Body ground	Engine switch on (IG)	9 to 14 V

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR (TCM - ECM) 

OK: Go to next step 

1. Disconnect the TCM connector.

2. 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 Position	Specified Condition
   B40-15 (R) - Body ground	R	11 to 14 V *
   	Except R	Below 1 V
   B40-16 (D) - Body ground	D	11 to 14 V
   	Except D	Below 1 V

   HINT: 

   *: The voltage will drop slightly because the back up light is turned on.

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR (PARK/NEUTRAL POSITION SWITCH - TCM) 

OK → REPLACE TCM
