Normal Operation
WARNING: This page is about a different car, the 2010 Mercury Milan, 2010 Lincoln MKZ, and 2010 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
The key removal inhibit solenoid (part of the ignition switch) receives battery voltage from Smart Junction Box (SJB) fuse 27 (20A) through circuit SBP27 (BU/RD). When the selector lever is moved out of the PARK position, the park range switch (part of the selector lever) closes and connects circuit CET22 (GY/BN) to circuit GD116 (BK/VT), providing ground to the key removal inhibit solenoid. The key removal inhibit solenoid activates and prevents the ignition lock cylinder from being turned to the OFF position and the key removed.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Ignition switch
- Selector lever
