Bypass Parking Brake Wire

The android head unit in the car is to be signaled via the brake wire.

It comprises a wire that connects solely to the amp remote wire and parking brake wire at the back of the radio, as well as a wire that supplies power and grounds.

These devices are used for radios that employ an on/off/on sequence to verify that the e-brake is applied.

Direct connection to the ground is possible with simpler radios looking for a ground signal via the park brake radio line.

If you require the true bypass, you must understand the signal type the radio is looking for.

How To Bypass The Parking Brake Wire?

Parking brake mode has been included to discourage drivers from watching movies while driving. Driving and watching DVDs at the same time is dangerous.

The methods for bypassing parking brake wires are shown below. Parking brake bypass then won’t be a problem.

Grounding The Head Unit Of The DVD Player

It is a common technique for DVD players connected to the brake interlock system. The technique is also applicable to aftermarket DVD models. Remember to turn the ignition off before starting.

  1. Utilizing the removal tools, remove the plastic trim from the head unit. To access the two screws holding that trim surround, pull up the left side just enough.
    Pull the radio out of the din slot and away from the dash after loosening the trims’ attachment point.
  2. Find the green wire and the black wire. It is the black ground wire 12-volt at the back of the head unit. Consult the DVD player’s user manual if you need clarification.
  3. From the brake interlock system, disconnect the parking brake cable. You can also chop it off at the midpoint.
    Use electrical tape to wrap the remaining end. You must strip the parking brake wire’s head unit end to reveal the ends.
  4. Obtain the ground wire that joins the car’s chassis to the DVD player head unit. Then, split it in two. Remove the ground wire’s two ends.
    Ensure you remove the insulation from the three ends, leaving the wires exposed by between 1/4 and 1/2 inches.
  5. Use sturdy tape to join the wire’s exposed ends. Around each connection point, put another layer.
  6. Use the screws you removed to mount your car’s head unit after you’ve mounted it.
    Before starting the vehicle, install one side of the plastic bracket and then the other. If everything goes as planned, this should work.

Some DVD players can recognize hacks and temporarily halt video playback. If the radio continued to function after bypassing and stopping, this might be the problem.

Using Toggle Switch

The second method we use involves installing a little switch. Any momentary toggle switch is acceptable. You might use a toggle switch to bypass the parking brake when driving.

  1. Utilizing the removal tools, remove the plastic trim from the head unit. To access the two screws holding that trim surround, pull up the left side just enough.
    Pull the radio out of the din slot and away from the dash after loosening the trims’ attachment point.
  2. Find the green wire and the black wire. It is the black ground wire 12volt ground at the back of the head unit. Consult the DVD player’s user manual if you need clarification.
  3. From the interlock system, disconnect the parking brake cable. You can also chop it off at the midpoint.
    Use electrical tape to wrap the remaining end. You must strip the parking brake wire’s head unit end to reveal the ends.
  4. Obtain the ground wire that joins the car’s chassis to the DVD player head unit. Then, split it in two.
    Remove the ground wire’s two ends. Ensure you remove the insulation from the three ends, leaving the wires exposed by between 1/4 and 1/2 inches.
  5. Connect the toggle switch’s one end to the head unit’s parking brake wire. You should connect the other end wire to the ground.
    The stereo player may now be replaced, the trim cover secured, and you can ensure the toggle switch is visible and reachable.
  6. Flip the toggle switch off to stop watching a video while driving. The parking brake bypass switch is what it is. Drive your vehicle for a while before turning the switch back on.

Using Relay

Installing a relay is necessary to help circumvent the parking brake on more recent pioneer models. You must first obtain the proper relay switch.

  1. Eliminate the amplifier’s remote ground signal cable connection. After that, join it to the power pin of the relay.
  2. Connect a ground wire to the coil’s one side. The car chassis can be linked to all ground connections.
  3. Pick up a second ground wire. Run it from the open contact after that.
  4. Connect pin 30 on the relay switch with the pink or green parking brake cable. The connection type will be an open circuit until the boss DVD player is turned on.
  5. After being turned on, the device will check the parking brake wire before turning on the remote power. The amp will then turn on and trip the relay switch after that.

The relay switch will discharge ground onto the parking brake cable when triggered. The parking brake sensor is disregarded whenever the DVD player model is turned on.

FAQs

What Does The Parking Brake Do On A Car Stereo?

The purpose of a parking brake is to prevent your car from rolling while parked. The brake pedal must be applied every time you park a manual gearbox vehicle.
