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

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   J43-5 (E) - Body ground	Always	Below 1 Ω

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. Disconnect the transmission control switch connector.

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
   J43-3 (IG) - Body ground	Engine switch on (IG)	11 to 14 V
   	Engine switch off	Below 1 V

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. Disconnect the transmission control switch connector.

2. Measure the resistance between each terminal of the transmission control switch when the shift lever is moved to each position.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   3 (IG) - 7 (S)	Shift lever in M, "+" or "-"	Below 1 Ω
   	Shift lever not in M, "+" or "-"	10 kΩ or higher
   2 (SFTU) - 5 (E)	Shift lever held in "+" (Up-shift)	Below 1 Ω
   	Shift lever not held in "+"	10 kΩ or higher
   1 (SFTD) - 5 (E)	Shift lever held in "-" (Down-shift)	Below 1 Ω
   	Shift lever not held in "-"	10 kΩ or higher

NG → See step   6 

OK: Go to next step 

1. Connect the transmission control switch connector.

6. Disconnect the spiral cable connector.
7. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   A6-8 (SFTU) - Body ground	Shift lever held in "+" (Up-shift)	Below 1 Ω
   	Shift lever not held in "+"	10 kΩ or higher
   A6-7 (SFTD) - Body ground	Shift lever held in "-" (Down-shift)	Below 1 Ω
   	Shift lever not held in "-"	10 kΩ or higher

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK → See step   5
