How To Bypass Parking Brake In Pioneer Car Stereo

If your goal is to unwind and savor the ride, the Pioneer parking brake might hinder your plans. 

The Pioneer car stereo intends to entertain passengers without distracting the driver. Additionally, many governments have imposed restrictions on installing DVD screens in the front for safety concerns. 

Hence, while the brake is in place for safety purposes, most individuals are curious about bypassing it to utilize their devices. 

This blog post explains how to bypass parking brake in pioneer car stereo like a pro.

How To Bypass Parking Brake In Pioneer Car Stereo

The incorporation of parking brake mode serves as a preventive measure to deter drivers from engaging in video viewing while actively operating their vehicles. 

The methodology for effectively bypassing the DVD player varies depending on the particular car model and the specifications of the DVD player.

Outlined below are several widely recognized approaches to circumvent the DVD player, thereby enabling passengers to partake in video entertainment while the vehicle is in motion: 

1. Ground the Head Unit of the DVD Player

Parking brake mode is a widely adopted strategy in many older car models and DVD players integrated with brake interlock systems.

When employing this method, the DVD player can detect the activation status of the parking brake, allowing video playback exclusively when the brake is engaged.

To bypass such a DVD player, one must disconnect the head unit from the interlock system of the brake and establish a connection with the black ground wire. 

This involves detaching the parking brake wire from the interlock system or cutting it midway. 

The remaining end is then securely wrapped with electrical tape, while the exposed end of the parking brake wire originating from the head unit is stripped to reveal the conductive portion.

To accurately identify the parking brake and ground wires, consulting the user manual of the specific DVD player is advised, especially when dealing with aftermarket DVD units. 

Additionally, before commencing the procedure, it is essential to ensure that the ignition key is turned off.

Step 1

Carefully dismantle the plastic trim surrounding the head unit using the appropriate removal tools.

Once the attachment points of the trim are released, extract the radio from the din slot and gently remove it from the dashboard.

Step 2

With the radio successfully extracted from the dashboard, locate the black 12-volt ground wire and the light green parking brake wire at the rear of the head unit.

If any uncertainty arises, referring to the user manual for the DVD player will aid in accurately identifying the parking brake and ground wires.

Step 3

Disconnect the parking brake wire from the interlock system or cut it at an intermediate point.

Next, securely wrap the remaining end with electrical tape. To expose the ends, strip the section of the parking brake wire originating from the head unit.

Proceed to cut the ground wire connecting the DVD player head unit to the car chassis, ensuring it is cut midway. Strip both ends of the ground wire, leaving approximately ¼ to ½ inch of exposed wire.

Step 4

Meticulously join the exposed ends of the wires, ensuring a seamless connection, and apply an additional layer of tape around each connection point.

Step 5

Once the car’s head unit is securely reinstalled, use the screws removed in step 2 to fasten it firmly.

Next, install one side of the plastic trims individually, then install the other side before starting the vehicle. This method should yield the desired outcome if all steps have been followed accurately.

It should be noted that some modern DVD players can detect such bypass attempts, potentially causing temporary interruption of video playback. 

If the radio was functioning correctly after the bypass but suddenly stopped, this may be the underlying issue.

For the bypass to function effectively, the head unit must detect the grounding before activation. 

If any issues arise, disconnecting the parking brake wire and reconnecting the brake to the ground wire should resolve the problem.

2. Using Toggle Switch to Bypass Parking Brake in Pioneer Car Stereo

If you find the previously mentioned method uncomfortable and possess an older DVD player, an alternative option is using a toggle switch to bypass the player while driving.

To initiate the process, follow steps 1 to 3 as outlined in the earlier method to expose the pertinent wires effectively.

Following this, connect one end of the toggle switch to the parking brake wire originating from the head unit, while the other end is connected to two ground wires.

Once the connection is established, replace the stereo player, securely affix the trim cover, and ensure the toggle switch remains easily accessible and visible.

Switch to the “off” position to enjoy video playback while driving. Start your vehicle, drive, and toggle the switch back to the “on” position.

3. Using Relay

Another way to bypass the parking brake in Pioneer car stereo involves successfully installing a relay switch to bypass the parking brake.

Before initiating the installation process, it is imperative to procure the appropriate relay switch and meticulously follow the subsequent steps to facilitate the installation, enabling a seamless bypass of the DVD player while driving.

Step 1

Begin by severing the remote signal wire connection to the amplifier and establishing a new connection to the relay’s power pin (pin 86). 

Simultaneously, route a ground wire from one side of the coil (pin 85), ensuring that all ground connections are diligently wired to the car chassis.

Step 2

Subsequently, utilize an additional ground wire and route it from the open contact point.

Step 3

Connect the pink or green parking brake wire from the head unit to pin 30 on the relay switch. 

It is important to note that this connection will remain an open circuit until the DVD player receives power.

The DVD player will perform an initial check on the parking brake wire after powering the unit. Once the booting process is completed, it will engage the remote power functionality, powering the amplifier and triggering the relay switch.

When the relay switch is activated, it will establish a ground connection with the parking brake wire. 

As a result, whenever the DVD player is turned on, it will effectively bypass the parking brake sensor, ensuring uninterrupted operation.
