Pinpoint Test E : The Ignition Key Can Be Turned To The Off Position When The Selector Lever Is Not In Park

WARNING: This page is about a different car, the 2018 Lincoln Navigator. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.

NOTE: The following Pinpoint Test uses a test lamp to simulate normal circuit loads. Use only a Rotunda Test Lamp (SGT27000) or 250- 300mA incandescent bulb test lamp. To avoid connector terminal damage, use the Rotunda Flex Probe kit for the test lamp probe connection to the vehicle. Do not use the test lamp probe directly on any connector.

E1 CHECK THE KEY INHIBIT SOLENOID CIRCUIT FOR GROUND

Ignition OFF.

Disconnect Ignition Switch C250 .

Set the park brake.

Select NEUTRAL.

Connect:

Positive Lead	Measurement / Action	Negative Lead

Is the test lamp illuminated?

Yes

GO to E2

GO to E4

E2 CHECK THE IGNITION SWITCH
- Ignition OFF.
- Disconnect Ignition Switch C250 .
- Carry out the Ignition Switch Component Test. Refer to Wiring Diagram Component Testing for schematic and connector information.
Does the ignition switch pass the component test?

Yes GO to E3

No INSTALL a new ignition switch. REFER to:Ignition Switch .

E3 CHECK THE BCM (BODY CONTROL MODULE) KEY INHIBIT GROUND CONTROLLED CIRCUIT FOR AN OPEN

Ignition OFF.

Disconnect BCM C2280B .

Measure:

Remove the fused jumper wire.

Does the test lamp illuminate with the fused jumper wire connected?

Yes	INSTALL a new brake shift interlock actuator. REFER to: Brake Shift Interlock Actuator .

No	REPAIR the circuit.

E6 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION

Disconnect and inspect all BCM connectors.

Repair:
- corrosion (install new connector or terminals - clean module pins)
- damaged or bent pins - install new terminals/pins
- pushed-out pins - install new pins as necessary

Reconnect the BCM connectors and all other previously disconnected connectors. Make sure they seat and latch correctly.

Operate the system and determine if the concern is still present.

Is the concern still present?

Yes

CHECK OASIS for any applicable service articles: TSB, GSB, SSM or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no service articles address this concern, BCM guided routine is not applicable for this vehicle and market. Replace the component that was faulted through service information diagnosis.

No	The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
