- I1 CHECK THE KEY REMOVAL INHIBIT SOLENOID CIRCUIT FOR GROUND
- Select NEUTRAL.
- Disconnect: Ignition Switch C250.
- Measure the resistance between ignition switch C250-3, circuit CET22 (GY/BN), harness side and ground.
- Is the resistance less than 5 ohms?
- Yes : INSTALL a new ignition switch. REFER to IGNITION SWITCH in this service information. TEST the system for normal operation.
- No : GO to I2 .
- I2 CHECK THE KEY REMOVAL INHIBIT SOLENOID CIRCUIT FOR AN OPEN
- Disconnect: Floor Shifter C3233.
- Measure the resistance between ignition switch C250-3, circuit CET22 (GY/BN), harness side and floor shifter C3233-2, circuit CET22 (GY/BN), harness side.
- Is the resistance less than 5 ohms?
- Yes : GO to I3 .
- No : REPAIR circuit CET22 (GY/BN). TEST the system for normal operation.
- I3 CHECK THE FLOOR SHIFTER GROUND CIRCUIT FOR AN OPEN
- Measure the resistance between floor shifter C3233-5, circuit GD116 (BK/VT), harness side and ground.
- Is the resistance less than 5 ohms?
- Yes : INSTALL a new selector lever. REFER to AUTOMATIC TRANSAXLE/TRANSMISSION EXTERNAL CONTROLS - AISIN AW21/6F35 -- FUSION, MILAN & MKZ (EXCEPT HYBRID) article or AUTOMATIC TRANSAXLE/TRANSMISSION EXTERNAL CONTROLS - FUSION HYBRID, MILAN HYBRID & MKZ HYBRID article. TEST the system for normal operation.
- No : REPAIR circuit GD116 (BK/VT). TEST the system for normal operation.
