Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Inspection Procedure
- CHECK HARNESS AND CONNECTOR (SPIRAL CABLE - BODY GROUND)
- Disconnect the steering pad switch connector and spiral cable connector
- Measure the resistance according to the value(s) in the table below
Standard Resistance
STANDARD RESISTANCE SPECIFICATIONTester 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
- INSPECT SPIRAL CABLE SUB-ASSEMBLY
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
STANDARD RESISTANCE SPECIFICATIONTester 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
- Measure the resistance according to the value(s) in the table below.
- INSPECT TRANSMISSION SHIFT SWITCH ASSEMBLY
- Disconnect the switch wire connector from the transmission shift switch.
- Measure the resistance between each terminal when the paddle shift is moved to each position.
Standard Resistance
STANDARD RESISTANCE SPECIFICATIONTester 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
- CHECK HARNESS AND CONNECTOR (SPIRAL CABLE - TRANSMISSION SHIFT SWITCH)
- Connect the switch wire connector to the transmission shift switch.
- Measure the resistance between each terminal when the paddle shift is moved to each position.
Standard Resistance
STANDARD RESISTANCE SPECIFICATIONTester 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
- CHECK HARNESS AND CONNECTOR (SPIRAL CABLE - ECM)
- Connect the spiral cable connector and steering pad switch connector.
- Disconnect the ECM connector.
- Disconnect the transmission control switch connector.
- Measure the resistance according to the value(s) in the table below when the paddle shift is moved to each position.
Standard Resistance
STANDARD RESISTANCE SPECIFICATIONTester 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: PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE (See PROBLEM SYMPTOMS TABLE )

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
