Title: HYBRID / BATTERY CONTROL: HYBRID CONTROL SYSTEM (for LITHIUM-ION BATTERY): Shift Paddle Switch Circuit; 2020 - 2024 MY Camry HV [09/2019 - ]

Shift Paddle Switch Circuit

DESCRIPTION

Moving the shift lever to S enables the shift range to be selected. The shift range can be selected by operating the "+" or "-" shift paddle switch.

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.

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 K70 hybrid vehicle control ECU assembly connector.

(b) Disconnect the K29 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
K70-9 (SFTU) - Body ground	Shift paddle switch RH (+) operated	3 Ω or less
K70-8 (SFTD) - Body ground	Shift paddle switch LH (-) operated	3 Ω or less
K70-9 (SFTU) - Body ground	Shift paddle switch RH (+) not operated	10 kΩ or higher
K70-8 (SFTD) - Body ground	Shift paddle switch LH (-) not operated	10 kΩ or higher

(d) Reconnect the K29 transmission control switch (shift lock control unit assembly) connector.

(e) Reconnect the K70 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 K22 spiral cable sub-assembly connector.

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

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

Standard Resistance (Open):

Tester Connection	Condition	Specified Condition
K22-2 (ECC) - Body ground	Always	Below 1 Ω

REPAIR OR REPLACE HARNESS OR CONNECTOR

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

(a) Disconnect the K70 hybrid vehicle control ECU assembly connector.

(b) Disconnect the K22 spiral cable with sensor sub-assembly connector.

Standard Resistance:

Tester Connection	Condition	Specified Condition
K70-9 (SFTU) - K22-8 (SUP)	Always	Below 1 Ω
K70-8 (SFTD) - K22-1 (SDN)	Always	Below 1 Ω
K70-9 (SFTU) or K22-8 (SUP) - Body ground	Always	10 kΩ or higher
K70-8 (SFTD) or K22-1 (SDN)- Body ground	Always	10 kΩ or higher

8.	INSPECT NO. 1 SWITCH WIRE

(a) Disconnect the z4 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
z4-2 (SUP) - z4-3 (ECC)	"+" (Up shift) shift paddle switch operated and held	Below 1 Ω
z4-2 (SUP) - z4-3 (ECC)	"+" (Up shift) shift paddle switch not operated	10 kΩ or higher
z4-4 (SDN) - z4-3 (ECC)	"-" (Down shift) shift paddle switch operated and held	Below 1 Ω
z4-4 (SDN) - z4-3 (ECC)	"-" (Down shift) shift paddle switch not operated	10 kΩ or higher
