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

   Standard voltage

   Tester Connection	Specified Condition
   RB (C1-1) - Body ground	10 to 14 V

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. Disconnect the park/neutral position switch connector.

2. Remove the ST relay from the engine room relay block.
3. Measure the resistance between the terminals.

   Standard resistance

   Tester Connection	Specified Condition
   L (C1-9) - ST relay terminal 1	Below 1 Ω

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 between the terminals.

   Standard resistance

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

NG → REPLACE ST RELAY 

OK: Go to next step 

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

2. Measure the resistance between the terminals

   Standard resistance

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

3. Install the ST relay.

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

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

   Standard resistance

   Shift Position	Tester Connection	Specified Condition
   P	1 - 3 and 4 - 9	Below 1 Ω
   Except P		10 kΩ or higher
   R	1 - 2	Below 1 Ω
   Except R		10 kΩ or higher
   N	1 - 8 and 4 - 9	Below 1 Ω
   Except N		10 kΩ or higher
   D, S, "+" and "-"	1 - 7	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 park/neutral position switch connector.

2. Disconnect the TCM connectors.
3. 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

   Shift Position	Tester Connection	Specified Condition
   R	R (C56-15) - Body ground	10 to 14 V *
   Except R		Below 1 V
   D	D (C56-16) - Body ground	10 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: Go to next step 

1. Disconnect the TCM connectors.

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

   Standard resistance (Check for open)

   Tester Connection	Specified Condition
   B (C1-4) - NSW (C56-11)	Below 1 Ω

   Standard resistance (Check for short)

   Tester Connection	Specified Condition
   B (C1-4) or NSW (C56-11) - Body ground	10 kΩ or higher

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK → REPLACE TCM
