2006 Ford F150: Will Not Shift out Of Park?

The Vehicle not shifting to drive or reverse mode.
The Gear shifter stuck in park mode.


When the shifter will not shift from Park,

• First- Check your rear brake lights to see if they are working when you step on the brake pedal.
• If the brake lights are NOT working, check your fuses. 
• If the fuses are good, and still no brake lights, then the problem will be the Stop Lamp Switch.

The Stop Lamp switch is  located at the top of the brake pedal arm.

Working of Stop Lamp switch:----
This switch controls the rear brake lights, and also sends a signal to the Shift Interlock, telling it to release when the brake pedal is depressed.

Carefully inspect the electrical connector for any loose, broken or damaged wires. If the visual inspection checks ok, replacing the switch will solve the problem.

See this help diagrams shown below for exact part location:-----



NOW think other way.

If the brake lights ARE working, then the problem is going to be in the Shift Interlock system. Most commonly, the Interlock Solenoid. The interlock solenois is located on the steering column, behind the steering wheel and clockspring assembly. Again, inspect the electrical connector for any damaged or loose wires. If the visual inspection checks ok, suspect a faulty Interlock Solenoid.

See the diagram showing the shift interlock solenoid



In this types of problems there aren't many other items involved in the Interlock System. It's the brake light switch, to the shift interlock solenoid, which releases the lock on the shift cable. Ford does not provide an "over-ride" procedure, however, on "SOME" models, turning the key to "ACC" and then shifting to Neutral does the trick. Also, sometimes, the shifter is just "hard" to shift from park due to an incline. Try to have someone push the vehcile a bit, and relieve some pressure on the rear wheels, and then try to shift. BUT If the Interlock solenoid is the culprit, then, it is what has to be replaced.

This details will help.
Thanks.

1996 Toyota Corolla: Transmission Shift Interlock will not Release?

Shift Lever Stuck in Park Mode.

In this types of cases,first check the Brake lights.Depress the brake pedal and see,is the brake lights coming ON or NOT.
Most of the cases this problem is due to shorted fuse.OR it can be the ECU/ECM  issue.ECU/ECM means The computer also called as Engine control module or Unit.


The brake stop light fuse does power up the shift lock ECU. The stop light fuse is mounted to the brake pedal bracket. The lower dash panel does not need to be removed to gain access to it. It is a tight reach and fit but all you need to do is break the 14 mm lock nut loose then the brake light switch unscrews. There is a single electrical connector with either two pins or four pins depending on whether not you have cruise control. Depress the lock tab and remove the electrical connector before unscrewing the stop light switch.

Before you do any of this though my recommendation would be to remove the left kick panel. In behind there you will find several connectors that go to the wiring harnesses that run along the left running board. Disconnect all these electrical connectors and see if the short goes away. If it does then you know the problem is somewhere to the rear brake light system. If the short is still there then the problem may be in the shift interlock solenoid itself in the center console.

At this point you would need to remove the center console and disconnect the connectors to the solenoid and computer. Sometimes stuff gets spilled into the solenoid and causes it to short out.

You will find the the 15 ampere fuses for the stop lights in the fuse box on the left driver's side of the car.Inspect/Test that fuses properly.If the fuses look blown out,then replace the fuse.

The 15 amp stop light fuse provides power to one side of the stop light switch when the stop light switch is activated or the pedal is depressed it closes the circuit and provides power to the shift interlock ECU and the brake lights. This is the only way the shift interlock computer/ECU knows that you have your foot on the brake and then will disengage the solenoid to allow the shifter to come out of Park. If you push down the bypass pressure switch on the center console it will allow you to temporarily get the shifter out of Park.


This details will help you.
Thanks.
