When Parked Apply Parking Brake Nissan Leaf?

I own a 2019 Leaf, so I thought I’d share my story in case it helps anyone else. The screen would display the above message, “When Parked Apply Parking Brake,” starting a few weeks ago when I turned it on, and at that time it wouldn’t move out of park. The automobile would occasionally start up fine, but while driving, the display would occasionally indicate a “T/M system fault.” After doing some online research, I discovered that individuals had had a problem with the 12V battery, so I bought a battery charger and connected it, trying various things with varying degrees of success. To make a long tale short, when I finally took the car to the shop, they discovered that the problem was a loose connector on the parking actuator relay, which is covered by Nissan service bulletin NTB19-054a. Within a few hours, they found the problem, fixed it, and covered it under warranty.

The internet was created for this purpose. Your advice prevented me from having to wait an hour for the tow truck while I had a pregnant wife, a toddler who had just received a flu vaccination, and me in the hot heat. That stupid device only needed to be pushed and pulled to work! Thank you so much for sharing it

Yes, I think the parking actuator that is impacted is for the parking brake. However, regardless of whether the parking brake was engaged or disengaged at the time the error notice appeared, I was unable to move the car out of Park.

I know that seems ridiculous, but I have the 2018 leaf. Is the p button a physical brake and the switch next to the cup holder an electrical parking brake? What makes you prefer one over the other? Does the button on the right with the clock and plug turn off the charging timer so I can charge immediately?

Yes, the button is next to the drink holder if you have an electronic parking brake. It should not be mistaken with the e-pedal, which is located next to the eco button. The P button places the transmission in park, but legally you should always have the car in park and engage the parking brake, which presses the brake pads on your back wheels into the disc rotor, when you’re parked.

Yes, even when you are outside the charge timer window, the clock+plug instructs your car to begin charging; however, if I’m not mistaken, it will continue to obey the shutoff time on your charge timer if one is set.

In whatever car I’ve ever owned, I’ve never used the parking brake, and I’ve never experienced any issues. I left the parking brake on in 1974 while operating a Volkswagen Bug and traveled about 10 miles. The car couldn’t have benefited from it. I might apply the parking brake if I lived in the San Francisco hills. Without that, nope.

went to the dealer, who eventually found the problem and rectified it. The proper cure is to replace the wire harness fully, which should be done by a mechanic. If you’re in a pinch and your car is stuck somewhere unsafe, you can try to fiddle with the relevant plug directly to get your car moving.


In regards to our 2017 Leaf 30, we have an issue. It no longer enters drive mode and flashes the warning. Apply a parking break and an I-Key warning while parked.

When my wife was driving home from work yesterday, everything all began. She stopped at a store, and as she tried to leave once more, she saw the I-Key warning. She then got out of the locked car, got back in, and drove home after the car had started. There was a whining sound coming from the outside of the car as she arrived at her house and got out, and there was a persistent beeping inside.

I attempted to move the automobile and spent several hours researching probable problems. The car reversed off the drive and back on without incident, but it has never since returned to drive mode. Occasionally, I could turn the automobile off, but these days, whenever I try to, it keeps starting up again. When you click the power button, the dash temporarily shuts off before turning back on, yet the satellite navigation system and stereo remain on all the time. The 12v battery must be disconnected in order to turn it off.

In relation to that, this is frequently cited as a flaw in children who are 3 or older. So, when I tried it last night, the charge was insufficient.

We therefore bought a new this morning, but the problem persists. Because the car won’t switch off, I had to unplug the battery to stop it from depleting.

On the dash, I’ve seen that the Security indication light, the 12-volt battery charge warning light, and the Electric shift control system warning light are all on. I’m not sure if this is a coincidence or a red herring.

Before going to the primary dealer, I’d prefer to rule out any obvious potential causes (as this car was purchased second hand). We can’t get the car into neutral, so I’m not sure how to proceed if it does need to go to the dealer.

I-Key system error: “When parked, use the parking brake” Leaf on a bench

I’m trying to convert a Rover Mini’s drivetrain to a Nissan Leaf. I bought a 2014 SL that was wrecked but still drivable, removed the complete electrical harness from the vehicle, and now I have it lying on a bench at my home. Since then, I’ve been attempting to get the motor to spin outside of the vehicle.

I have a brand-new, fully charged 12 volt battery connected to the automobile. Currently, when I press the power button, a few relays click, the dash illuminates, and I receive the following two messages:

Looking around, it appears that the 12 volt battery is the problem, but I’m confident that mine is in good condition. The pre-charge relay and resistor are also mentioned. Several relays click when I turn the power on, but none of them are in the container for the traction batteries (where these are located). Although it seems suspicious that the PRND indicator never illuminates, it is related…

The 12v wiring is not connected to the HVAC module, only the HV wiring. Though I don’t believe it should be necessary, the brake system and the rest of the vehicle are gone.

I’m a little perplexed right now. To make sure I’m not missing any connectors, I’ll start by disassembling the wire harness. But boy, that’s a long-winded stab in the dark. Is there a more organized approach to troubleshooting that I can use? Despite the fact that my wireless OBD adapter has a lighted LED when plugged in, LeafSpy won’t operate (it did when the car was complete).

With a dead battery, how do you release an electric parking brake?

Electric parking brakes are not intended to function when the batteries are dead. There are two ways to deactivate the electric park brake if your car’s battery is dead. Either you jump-start your automobile using a portable jump starter or another car, or you physically release the brake.

Additionally, in addition to a jack tool, a special tool is required to manually release it. Remove the plug from the tire well, attach the correct bit to the tool, enter the jack tool, and rotate it counterclockwise to release.

How does a Nissan Leaf release its parking brake?

In the footwell, far left, is where you’ll find the parking brake. Simply depress the parking brake pedal to release it. 3 Leaving via car. Choose “D” for drive or “R” for reverse while keeping your foot firmly on the brake pedal.

On a Nissan LEAF, how does Park operate?

ProPILOT Park will automatically park the vehicle in three simple steps by managing the steering, accelerator, brakes, gear shift, and parking brake. The technology will switch the transmission to “P” and engage the electronic parking brake after the parking process is complete.

Why does it say that my parking brake is engaged even when it is not?

A number of dashboard warning lights may suddenly begin to illuminate. Everyone is aware of the functions of the battery and oil lights, but many other lights call for consulting the owner’s manual. To assist make things a little clearer, we’ll look at several lights and what they represent in the upcoming months.

The parking brake warning light is displayed here. It can be either red or orange, depending on the brand of the car. It flashes to indicate that the parking brake or emergency brake is applied and needs to be disengaged before moving on with a drive.

It indicates that you need to add brake fluid if it stays lit after the parking brake is released or if it flashes intermittently while you’re driving. You must get the braking system checked if you check the fluid, add as necessary, and the light doesn’t go out.

In fact, you should get a brake inspection regardless of whether there is a leak in your brake system. Why? As your brake shoes or pads deteriorate, more fluid is needed to press them against the rotors or drums to stop the car. This dashboard light can be gently alerting you that brake servicing and repairs are about due.

The parking brake needs maintenance if there is an illuminated wrench under the light. The car can be operated safely, but it needs to see a mechanic.

When I put my car in park, why does my parking brake light up?

The transmission in your car is designed to deteriorate over time. You might not be aware of it, but simply parking causes your transmission to experience more wear. If you frequently park on an elevation, your transmission will be more negatively impacted. As a general rule, apply the e-brake before shifting into park. By doing this, you will reduce the stress on your parking pawl by allowing your brakes and parking mechanism to absorb the incline’s pressure on your car.

What is the mechanism of the parking brake?

When you use the parking brake, parking brake shoes—discs within your rear wheels that restrict your tires from spinning and prevent your car from rolling away—expand and press against the inner part of the wheel.

Consult your owner’s manual and adhere to these four simple procedures to utilize your parking brake correctly.

Press the ((P)) button or pull the lever to engage the parking brake.

You can relieve transmission stress by applying your e-brake before shifting into “park” and letting the hydraulic brake system handle the task!

When parking, should you apply the parking brake?

The quick response is “every time you park”! You should always engage your parking brake when parking, according to Driver’s Ed Guru, regardless of whether your car is a manual or automatic or the terrain is level or hilly.

Your safety and the safety of those around you depend on the parking brake. A parking pawl, which is essentially a device that locks up your transmission when you put your car in park, controls the brakes on your vehicle. Your car would roll away without it!

The pawl can malfunction or break for any variety of causes, just like any other component of your car. Even while it might appear that putting the car in “Park” is sufficient, frequently using the parking pawl might harm your transmission and the pawl (especially if you frequently park on steep inclines).

Pro-Tip: To reduce the strain on your transmission, give yourself an extra measure of security, assist minimize parking failure, and possibly even avoid future transmission repairs, engage the parking brake BEFORE putting the car into “Park” (and engaging the pawl). The two systems work better as a team; think of them as a dynamic duet!
