PROCEDURE

1.	READ VALUE USING TECHSTREAM (SPORTS SHIFT UP SIGNAL, SPORTS SHIFT DOWN SIGNAL)

(a) Connect the Techstream to the DLC3.

(b) Turn the power switch on (IG).

(c) Enter the following menus: Powertrain / Hybrid Control / Data List / Sports Shift UP Signal, Sports Shift DOWN Signal.

Powertrain > Hybrid Control > Data List

Tester Display
Sports Shift UP Signal
Sports Shift DOWN Signal

(d) Read the values displayed on the Techstream.

Normal Condition

Sports Shift UP Signal

Sport shift up switch status

ON or OFF

Shift paddle switch RH (+) operated: ON

Shift paddle switch RH (+) not operated: OFF

Sports Shift DOWN Signal

Sport shift down switch status

ON or OFF

Shift paddle switch LH (-) operated: ON

Shift paddle switch LH (-) not operated: OFF

Result	Proceed to
The Techstream display changes according to the shift paddle switch (transmission shift switch assembly) operation.	A
The Techstream display does not change according to the shift paddle switch (transmission shift switch assembly) operation.	B

(e) Turn the power switch off.

CHECK FOR INTERMITTENT PROBLEMS

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

(a) Disconnect the A30 hybrid vehicle control ECU assembly connector.

(b) Disconnect the G23 transmission control switch (shift lock control unit assembly) connector.

(c) Measure the resistance according to the value(s) in the table below when the shift paddle switch (transmission shift switch assembly) is moved to each position.

Standard Resistance:

Tester Connection	Condition	Specified Condition
A30-24 (SFTU) - Body ground	Shift paddle switch RH (+) operated	Below 2.5 Ω
A30-11 (SFTD) - Body ground	Shift paddle switch LH (-) operated	Below 2.5 Ω
A30-24 (SFTU) - Body ground	Shift paddle switch RH (+) not operated	1 MΩ or higher
A30-11 (SFTD) - Body ground	Shift paddle switch LH (-) not operated	1 MΩ or higher

(d) Reconnect the G23 transmission control switch (shift lock control unit assembly) connector.

(e) Reconnect the A30 hybrid vehicle control ECU assembly connector.

REPLACE HYBRID VEHICLE CONTROL ECU ASSEMBLY

3.	CHECK HARNESS AND CONNECTOR (SPIRAL CABLE SUB-ASSEMBLY - BODY GROUND)

(a) Disconnect the G20 spiral cable sub-assembly connector.

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

Standard Resistance (Open):

Tester Connection	Condition	Specified Condition
G20-2 (ECC) - Body ground	Always	Below 1 Ω

*a	Front view of wire harness connector (to Spiral Cable Sub-assembly)

REPAIR OR REPLACE HARNESS OR CONNECTOR

4.	CHECK HARNESS AND CONNECTOR (SPIRAL CABLE SUB-ASSEMBLY - HYBRID VEHICLE CONTROL ECU ASSEMBLY)

(a) Disconnect the A30 hybrid vehicle control ECU assembly connector.

(b) Disconnect the G20 spiral cable with sensor sub-assembly connector.

Standard Resistance:

Tester Connection	Condition	Specified Condition
A30-24 (SFTU) - G20-8 (SUP)	Always	Below 1 Ω
A30-11 (SFTD) - G20-1 (SDN)	Always	Below 1 Ω
A30-24 (SFTU) or G20-8 (SUP) - Body ground	Always	10 kΩ or higher
A30-11 (SFTD) or G20-1 (SDN) - Body ground	Always	10 kΩ or higher

8.	INSPECT NO. 1 SWITCH WIRE

(a) Disconnect the z5 No. 1 switch wire connector.

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

Standard Resistance:

Tester Connection	Condition	Specified Condition
z5-2 (SUP) - z5-3 (ECC)	"+" (Up shift) shift paddle switch operated and held	Below 2.5 Ω
z5-2 (SUP) - z5-3 (ECC)	"+" (Up shift) shift paddle switch not operated	1 MΩ or higher
