Repair procedures

Inspection

1.	Turn ignition switch OFF.

2.	Remove the battery and battery tray. (Refer to Engine Electrical System - "Battery")

3.	Disconnect the solenoid valve connector (A).

Check that the resistance is within the specification.

•	If DTC about the Torque Converter Control Solenoid Valve is found, replace according to the procedures removal / installation.

Removal

Replacing an on/off solenoid valve (SS-A, SS-B) does not require additional hydraulic pressure adjustment; however, the hydraulic pressure will need to be adjusted after replacing the VFS solenoid valve. If replacing the VFS solenoid valve; also replace the valve body assembly.
