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

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   J24-2 (ECC) - Body ground	Always	Below 1 Ω

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.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   J24-2 (ECC) - k1-6 (ECC)	Always	Below 1 Ω
   J24-9 (SUP) - k1-2 (SUP)	Always	Below 1 Ω
   J24-10 (SDN) - k1-3 (SDN)	Always	Below 1 Ω

NG → REPLACE SPIRAL CABLE SUB-ASSEMBLY 

OK: Go to next step 

1. Disconnect the switch wire connector from the transmission shift switch.

2. Measure the resistance between each terminal when the paddle shift is moved to each position.

   Standard Resistance

   Tester Connection	Paddle Shift Position	Specified Condition
   SUP - ECC	Pull continuously "+" (Up shift)	Below 1 Ω
   	Release "+" (Up shift)	10 kΩ or higher
   SDN - ECC	Pull continuously "-" (Down shift)	Below 1 Ω
   	Release "-" (Down shift)	10 kΩ or higher

NG → REPLACE TRANSMISSION SHIFT SWITCH ASSEMBLY 

OK: Go to next step 

1. Connect the switch wire connector to the transmission shift switch.

2. Measure the resistance between each terminal when the paddle shift is moved to each position.

   Standard Resistance

   Tester Connection	Paddle Shift Position	Specified Condition
   k1-2 (SUP) - k1-6 (ECC)	Pull continuously "+" (Up shift)	Below 1 Ω
   	Release "+" (Up shift)	10 kΩ or higher
   k1-3 (SDN) - k1-6 (ECC)	Pull continuously "-" (Down shift)	Below 1 Ω
   	Release "-" (Down shift)	10 kΩ or higher

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. Connect the spiral cable connector and steering pad switch connector.

2. Disconnect the ECM connector.
3. Disconnect the transmission control switch connector.
4. Measure the resistance according to the value(s) in the table below when the paddle shift is moved to each position.

   Standard Resistance

   Tester Connection	Paddle Shift Position	Specified Condition
   A6-8 (SFTU) - Body ground	Pull continuously "+" (Up shift)	Below 1 Ω
   	Release "+" (Up shift)	10 kΩ or higher
   A6-7 (SFTD) - Body ground	Pull continuously "-" (Down shift)	Below 1 Ω
   	Release "-" (Down shift)	10 kΩ or higher

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK → See step   6
