PROCEDURE

1.	READ VALUE USING TECHSTREAM (SPORT SHIFT SWITCH STATUS)

(a) Connect the Techstream to the DLC3.

(b) Turn the ignition switch to ON.

(d) Enter the following menus: Powertrain / Engine / Data List.

(e) According to the display on the Techstream, read the Data List.

Powertrain > Engine > Data List

Tester Display	Measurement Item	Range	Normal Condition	Diagnostic Note
Sport Shift Up SW	Sport shift up switch status	ON or OFF	ON: Shift lever held in "+" or "+" shift paddle switch operated OFF: Shift lever not held in "+" and "+" shift paddle switch released	-
Sport Shift Down SW	Sport shift down switch status	ON or OFF	ON: Shift lever held in "-" or "-" shift paddle switch operated OFF: Shift lever not held in "-" and "-" shift paddle switch released	-

CHECK FOR INTERMITTENT PROBLEMS

2.	CHECK HARNESS AND CONNECTOR (SHIFT PADDLE SWITCH CIRCUIT)

(a) Disconnect the ECM connector.

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

Standard Resistance:

Tester Connection	Condition	Specified Condition
A24-20 (SFTU) - A24-28 (ECCS)	"+" (Up shift) shift paddle switch operated and held	Below 2.5 Ω
A24-20 (SFTU) - A24-28 (ECCS)	"+" (Up shift) shift paddle switch not operated	1 MΩ or higher
A24-19 (SFTD) - A24-28 (ECCS)	"-" (Down shift) shift paddle switch operated and held	Below 2.5 Ω
A24-19 (SFTD) - A24-28 (ECCS)	"-" (Down shift) shift paddle switch not operated	1 MΩ or higher

GO TO STEP 4

3.	CHECK HARNESS AND CONNECTOR (ECM - BODY GROUND)

(a) Disconnect the ECM connector.

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

Standard Resistance:

Tester Connection	Condition	Specified Condition
A24-10 (E1) - Body ground	Always	Below 1 Ω

PROCEED TO NEXT SUSPECTED AREA SHOWN IN PROBLEM SYMPTOMS TABLE

REPAIR OR REPLACE HARNESS OR CONNECTOR (ECM - BODY GROUND)

4.	CHECK HARNESS AND CONNECTOR (SPIRAL CABLE SUB-ASSEMBLY - ECM)

(a) Disconnect the spiral cable sub-assembly connector.

(b) Disconnect the ECM connector.

Standard Resistance:

Tester Connection	Condition	Specified Condition
A24-20 (SFTU) - G20-8 (SUP)	Always	Below 1 Ω
A24-19 (SFTD) - G20-1 (SDN)	Always	Below 1 Ω
A24-28 (ECCS) - G20-2 (ECC)	Always	Below 1 Ω
A24-20 (SFTU) or G20-8 (SUP) - Body ground	Always	10 kΩ or higher
