Brake lockout cable connected to the shift interlock latch

If your 2007 Impala is stuck in park and the gear override silver button doesn't work, there may be a few potential problems that are causing the problem. Here are some common causes and troubleshooting solutions you can try: Brake light switch: The most common cause of this problem is a faulty brake light switch. The brake light switch is responsible for sending a signal to the shift interlock solenoid to release the shifter when the brake pedal is depressed and can prevent the shifter from releasing if the switch does not operate properly. Make sure your brake lights work by pressing on the brake pedal. If they don't work, it's probably a brake light switch issue that needs to be replaced. Shift Interlock Solenoid: The shift interlock solenoid is a mechanism that prevents the shifter from moving without pressing the brake pedal If the solenoid is faulty or a blown fuse can cause the shifter to go into park. Check the fuse connected to the shift interlock system and replace if necessary. If the fuse is good, the solenoid may need to be replaced. Shift Cable: The shift cable connects the shifter to the transmission and allows you to change gears. Damaged, loose, or misaligned cables can prevent the shifter from leaving the parking space. Inspect the shift cable for any obvious issues and make sure it is securely attached to the shifter and transmission. Shift lock control module: Some vehicles have a shift lock control module that ensures proper operation of the shift interlock system. Malfunction of this module can cause the problem. It may be necessary to use a diagnostic scan tool to check for any error codes associated with the module. Ignition switch: Faulty ignition under certain conditions

This is a problem with the brake sensor lockout. Most likely it is out of place or broken and shorting. It is on the brake pedal lever.

Do you have floor console shifter ?
Shift Interlock System A brake/shifter interlock system consists of the following:

• ignition switch (11572)
• brake pedal stoplight switch (13480)
• brake shift interlock module
• brake shift interlock solenoid assembly (attached to key interlock assembly)
• necessary wiring

On floor-shift vehicles, the ignition/shifter interlock cable (3F719):

• locks the floor shift transaxle range selector lever in the PARK position when the ignition switch is in the LOCK position.
• requires the floor shift transaxle range selector lever to be in the PARK position to turn the ignition switch to the LOCK position.

what car, you never said? NOR YEAR?
park lock out feature;. its broken , they do that. (BTSI system)
got A/T? or M/T both auto and stick shift have lockout.

no car/year, you get the generic answer.
there is a park lockout DEFEATER on most cars, (never on new cars,due to federal bs)

on the shift console, see the defeat device.
the operators guide covers this. its for EMERGENCIES.
pick one.

the A/T box,
Brakes + handle button press, unlocks BTSI

on 2005 and up , no bypass
if the key gets locked too, that tells you what is bad , on newer jeeps
on newer jeeps read this

this feature (pain) has many failure points.
any cable that jams, there are 2 , one to tranny or ignition
switch. and the brake solenoid unlocker in shift handle.
and the button, to unluck shifter, brake switch (no brake lights/)
to diagnosis it is easy , dismantle the console at shifter
then disconnect cables to find if one is stuck, (easy huh?)
and defeat the solenoid, by hand or 12v applied. and check the button
that it does in fact release.
NOT PARK LOCKOUT: (for if not on flat ground?)
reason 2 , driver, parked on a hill with tire to curb and did so
not setting brakes first (or bad ebrake ) and now the tranny parking
pawl is jammed , opps. so wiggle the steering and wiggle shifter,
or have some one push car forward (parked up hill on right) to release
parking pawl. (or gorilla it, ask bubba to muscle it out of park.)
if down hill , well, you get the idea..... pain.. gotta love A/Ts not.
Folks in Sanfranciso, just roll eyes at you, new in town>?

now the grand cherroke,, why not post car model, and year, dang.

Brake/Transmission Interlock Manual Override Your vehicle may be equipped with a shift lock manual override. The manual override may be used in the event that the shift lever should fail to move from PARK with the ignition switch in the ON position and the brake pedal pressed. To operate the shift lock manual override, perform the following steps: 1. Turn the ignition switch to the ON position without starting the engine. 2. Firmly set the parking brake. 3. Using a flat-bladed screwdriver, carefully remove the shift lock manual override cover, which is located on the PRNDL bezel. 4. Press and maintain firm pressure on the brake pedal. 5. Using the screwdriver, reach into the manual override opening. Press and hold the shift lock lever down. Interlock Manual Override end quote.
no all jeeps have this,

Brake light switch , wiring etc... Do you know how to test automotive electrical circuit's using a wiring diagram an a DVOM -digital volt ohm meter ? Free wiring diagrams here http://www.bbbind.com/free-tsb Enter vehicle info. Year , make , model an engine size . Under system click on transmission / transaxle .Under subsystem click on shift interlock . Click the search button an then the blue link . Test the electrical circuits .
Shift Interlock System An ignition/shifter interlock mechanism is installed to prevent shifting the transaxle out of the PARK position unless the ignition switch is rotated to RUN and the brake pedal is applied. The floor shift interlock system consists of:

• an actuator assembly integral to the ignition/shifter interlock cable assembly.
• a bracket retaining the actuator.
• the necessary wiring.

The solenoid is energized when the ignition switch is turned to the RUN position, locking the transaxle range selector lever in the PARK position. When the brake pedal is applied and the stoplight switch (13480) is activated, the ignition/shifter interlock actuator is deactivated and the transaxle range selector lever can be moved out of the PARK position.

Sounds like you may have an adjustment problem with the cable. There is an Interlock feature which keeps you from starting your car in gear.

In a nutshell, your car does not know it is in Park or Neutral- the 2 modes which allow the starter to work. You need to adjust the length of the cable to finetune the Lockout. Some cars also require a foot on the brake pedal to allow for starting and these 2 switches work together so that your car can not be started in gear or without a foot on the brake(some models).

as a safety precaution today's vehicles are not supposed to shift out of park until brake pedal is depressed. usually it is one of two things that might cause your dilema, 1- you have a bad brake light switch and truck does not release shifter since it does not recognize you brake pedal as being pushed or 2- a bad shift interlock switch. make sure your brake lights work if they are orerational than most likely you have a bad shift interlock switch, not an uncommon problem. if this was helpful please leave positive rating.

There are few things that has to be checked 1)Transmission Lockout switch on the brake pedal 2) If transmission lockout switch checked out OK , then the solenoid on the gear lever that is activated by that switch has to be checked. 3)Step on the brake pedal and see if the brake lights come on. If they don't, check the brake light fuse to see if it is blown.
If they the brake lights come on, then turn the key to where the steering wheel unlocks, but no lights come on. Set the park brake and see if the shifter will shift into neutral.
If the shifter moves out of park, then you will need to check the shift interlock actuator as its not getting power when the brake pedal is depressed. Thanks. you can rate this solution and show your appreciation.

There is what is called a shift interlock mechanism. It is suppose to keep you from putting it into gear withut putting your foot on the break.

Do a quick test. See if your brake lights come on when you press the brake peddle. If they do, you will have to go into the wireing of the brake switch and see if power is coming out of the switch to the interlock solenoid. If power is going to the solenoid, then you have a bad solenoid.

Hope this helps.

There are actually 2 pink release buttons. The one at the right rear of the shifter is the brake interlock. The other one is at the left front with a cable attached to it and it is the reverse lockout. There are 2 steps to getting out of P. Try it without pressing the brake and you'll notice that you can't even move the stick to the right to leave P. Press the brake (or press the pink brake interlock tab down) and you'll be able to move the stick to the right and a little bit back toward R but you won't be able to get into R. That's where the other pink piece comes in. Push this pink piece straight towards the rear of the car and you'll bypass the reverse lockout.

This gets you moving but now to figure out why the reverse lockout is not working correctly. Anyone know the solution?
