SL Solenoid

WARNING: This page is about a different car, the 2002 Toyota Land Cruiser, 2002 Lexus LX 470, 2001 Toyota Land Cruiser, and 2001 Lexus LX 470. However, it is still accessible from the selected car via links, so may be relevant.

To check solenoid seals, remove suspect solenoid. See Fig 1. Connect battery voltage to solenoid. Apply 71 psi (5 kg/cm² ) to solenoid with battery voltage connected. See Fig 2.
With battery voltage applied, air should not pass through solenoid. Disconnect voltage to solenoid. Ensure air does pass through solenoid. Replace solenoid if defective.
