Pinpoint Test H: The Ignition Key Can Be Turned to the OFF Position When the Selector Lever is Not in PARK
Refer to Wiring Diagram Set 37 (Escape/Mariner, Escape Hybrid/Mariner Hybrid), Shift Interlock for schematic and connector information. Diagrams By Number
Normal Operation
The key removal inhibit solenoid (part of the ignition switch) receives battery voltage from 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 CDC41 (WH/BN) to circuit GD112 (BK/GN), providing ground to the key removal inhibit solenoid. The key removal inhibit solenoid activates and prevents the ignition key from being turned to the OFF position.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Ignition switch
- Selector lever
PINPOINT TEST H: THE IGNITION KEY CAN BE TURNED TO THE OFF POSITION WHEN THE SELECTOR LEVER IS NOT IN PARK
NOTICE: Use the Flex Probe Kit for all test connections to prevent damage to the wiring terminals. Do not use standard multi-meter probes.

H1 CHECK THE KEY REMOVAL INHIBIT SOLENOID CIRCUIT FOR GROUND
- Select NEUTRAL.
- Measure the resistance between ignition switch C250-3, circuit CDC41 (WH/BN), harness side and ground.
- Is the resistance less than 5 ohms?
Yes
INSTALL a new ignition switch. REFER to Ignition Switch Ignition Switch. TEST the system for normal operation.
No
GO to H2.
-------------------------------------------------
H2 CHECK THE KEY REMOVAL INHIBIT SOLENOID CIRCUIT FOR AN OPEN
- Disconnect: Floor Shifter C2096.
- Measure the resistance between ignition switch C250-3, circuit CDC41 (WH/BN), harness side and floor shifter C2096-2, circuit CDC41 (WH/BN), harness side.
- Is the resistance less than 5 ohms?
Yes
GO to H3.
No
REPAIR circuit CDC41 (WH/BN). TEST the system for normal operation.
-------------------------------------------------
H3 CHECK THE FLOOR SHIFTER GROUND CIRCUIT FOR AN OPEN
- Measure the resistance between floor shifter C2096-4, circuit GD112 (BK/GN) harness side and ground.
- Is the resistance less than 5 ohms?
Yes
INSTALL a new selector lever. REFER to Automatic Transaxle/Transmission External Controls - 6F35 Service and Repair or Automatic Transaxle/Transmission External Controls - Hybrid . TEST the system for normal operation.
No
REPAIR circuit GD112 (BK/GN). TEST the system for normal operation.
