WARNING: This page is about a different car, the 2010 Lincoln MKX and 2010 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: 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.
- Disconnect: Ignition Switch C250.
- 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 . TEST the system for normal operation.
- No: GO to H2 .
H2 CHECK THE KEY REMOVAL INHIBIT SOLENOID CIRCUIT FOR AN OPEN
- Disconnect: Floor Shifter C3245.
- Measure the resistance between ignition switch C250-3, circuit CDC41 (WH/BN), harness side and floor shifter C3245-2, circuit CDC41 (WH/BN), harness side.
