S46B Liftgate Unlatch Switch

1. Ignition/Vehicle Off
2. Disconnect the electrical connector: S46B Liftgate Unlatch Switch
3. Test for infinite resistance between the test points: Signal terminal 1 & Ground terminal 2 - Not Pressed
   • If less than infinite resistance 

     Replace the component: S46B Liftgate Unlatch Switch

   • If infinite resistance 
4. Test for less than 3 Ω between the test points: Signal terminal 1 & Ground terminal 2 - Pressed
   • If 3 Ω or greater 

     Replace the component: S46B Liftgate Unlatch Switch

   • If less than 3 Ω
