2. Check the connectors of TCM and CVT unit for water intrusion, or damage or corrosion of the terminals.
Is the inspection result normal?
YES >>
GO TO 3.
NO >>
Repair or replace damaged parts.
CHECK DETECTED DTC

Are other solenoid valve malfunctions detected in addition to select solenoid valve?
YES >>
GO TO 4.
NO >>
GO TO 7.

CHECK SOLENOID GROUND CIRCUIT - 1

Connect TCM harness connector.

Check continuity (resistance) between CVT unit harness connector terminal and ground.

CVT unit		—	Continuity (Resistance)
Connector	Terminal	—	Continuity (Resistance)
F46	20	Ground	Existed (1 Ω or less)

Is the inspection result normal?

YES >>

GO TO 6.

NO >>

GO TO 5.

CHECK SENSOR GROUND CIRCUIT - 2

Disconnect TCM harness connector.

Check continuity (resistance) between TCM harness connector terminal and CVT unit harness connector terminal.

TCM		CVT unit		Continuity (Resistance)
Connector	Terminal	Connector	Terminal	Continuity (Resistance)
F23	44	F46	20	Existed (1 Ω or less)

Is the inspection result normal?

YES >>

GO TO 6.

NO >>

Repair harness or connector.

CHECK TCM POWER SUPPLY AND GROUND CIRCUITS

Check TCM power supply and ground circuits. Refer to Diagnosis Procedure.

Is the inspection result normal?
YES >>
INSPECTION END
NO >>
Repair or replace damaged parts.

CHECK SELECT SOLENOID VALVE CIRCUIT - 1

Check continuity between TCM harness connector terminal and CVT unit harness connector terminal.

TCM		CVT unit		Continuity (Resistance)
Connector	Terminal	Connector	Terminal	Continuity (Resistance)
F23	37	F46	4	Existed (1 Ω or less)

Is the inspection result normal?

YES >>

GO TO 8.

NO >>
