2. Turn the engine switch on (IG).
3. Measure the voltage according to the value(s) in the table below.

   Standard voltage

   Tester Connection	Switch Condition	Specified Condition
   B36-1 (RB) - Body ground	Engine switch on (IG)	11 to 14 V

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. Turn the engine switch on (IG).

2. Remove the ST relay from the engine room relay block.
3. Measure the resistance according to the value(s) in the table below.

   Standard resistance

   Tester Connection	Condition	Specified Condition
   B36-9 (L) - ST relay terminal 1	Always	Below 1 Ω
   B36-9 (L) - Body ground	Always	10 kΩ or higher

4. Install the ST relay.
5. Reconnect the park/neutral position switch connector.

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. Remove the ST relay from the engine room relay block.

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

   Standard resistance

   Tester Connection	Condition	Specified Condition
   3 - 5	Always	10 kΩ or higher
   3 - 5	Always	Below 1 Ω Apply battery voltage between terminals 1 and 2

3. Install the ST relay.

NG → REPLACE ST RELAY ASSEMBLY 

OK: Go to next step 

1. Remove the ST relay from the engine room relay block.

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

   Standard resistance

   Tester Connection	Condition	Specified Condition
   ST relay terminal 2 - Body ground	Always	Below 1 Ω

3. Install the ST relay.

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. 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 → See step   10 

OK: Go to next step 

1. Connect the park / neutral position switch connector.

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 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 due to lighting up of the back up light.

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK → See step   11 

1. Disconnect the TCM connectors.

3. Measure the resistance according to the value(s) in the table below.

   Standard resistance (Check for open)

   Tester Connection	Condition	Specified Condition
   B36-4 (B) - B40-11 (NSW)	Always	Below 1 Ω

   Standard resistance (Check for short)

   Tester Connection	Condition	Specified Condition
   B36-4 (B) or B40-11 (NSW) - Body ground	Always	10 kΩ or higher

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK → See step   9
