B85 Rear Compartment Lid Key Cylinder Switch-Dynamic Test

1. Ignition/Vehicle - Off
2. Disconnect the electrical connector: B85 Rear Compartment Lid Key Cylinder Switch
3. Test for infinite resistance between the test points: Signal terminal 1 & Ground terminal 2 - The switch is in the open position.
   • If less than infinite resistance 

     Replace the component: B85 Rear Compartment Lid Key Cylinder Switch

   • Go to next step: If infinite resistance 
4. Test for less than 3 ohms between the test points: Signal terminal 1 & Ground terminal 2 - The switch is in the closed position.
