Frequently Asked Questions about technical topics in relation with installations, problems or Digi4Park® way of work. Also you will get information about simple and common errors that you can commit and how to solve them in the simple way.
Information on connection points signals in order to connect D4P to the CAN BUS vehicle is not listed in the manual because D4P vary depending on the vehicle model. But step by step we will be including this information in the files of each D4P compliant vehicles that are published on the web for both GROUP II to the III.
Locate your vehicle [FIND YOUR CAR] page provided before each installation, to see if there is extensive information on the specific vehicle on which you are installing.
D4P control unit must be installed close to the car radio unit place as we usually read the required information from the CAN BUS radio (infotainment). However, in some vehicles such information may not in radio or do not enter it but MOST CAN information. In this case the vehicle should look in the database D4P car to check the connection points.
Remember that the information BB.DD. of D4P is constantly updating and which complements the universal information shown in the installation manual. In the event that the CAN BUS is not present on the radio and also not report on its connection point or unknown, please contact us via tikets system so we can provide extended information about the connection. Remember that you need the SERIAL NUMBER of your D4P control unit to request such information.
This is a really important question. There are two points to keep in mind when painting the sensors:
To paint the sensors conveniently has two options. Use masking tape to protect the system thread or use the template incorporating D4P boxes. Within the instructions you find a painted sheet which reports the process to follow to use the box, painted template and useful punch to make holes in the box D4P. No problem if the rubber that is inserted into the sensor side but should paint the sensor without the rubber finish, and standing upon completion of installation.
Furthermore remember D4P sensors are aluminum and are painted factory black. Normally the black color is the most used in vehicles since many of them incorporate defenses or black bumpers for the area of the sensors while the car of another color. If the sensors be painted another color should lightly sand the sensors before painting again (you will see the aluminum surface behind the black paint), otherwise the new paint will not properly set and also subtracted detection power sensor.

NORMALLY NOT. In Digi4Park® we have tested radar detection systems such as Stinger or with assistance systems such as Distronic driving system by Mercedes Benz and have had no interference problems. Note that the wiring has a mesh D4P protection against electromagnetic interference and also the information sent by the wiring is digital, so that information is only taken into account if it arrives without errors. If there were any errors in the data, the information is eliminated.
Notwithstanding own electronic sensor itself may be subjected to interference. This Digi4Park® protection is working on both magnetic and electronic level to be included in the production phase of the product (MAY 2014) . Currently in preproduction product, external EMI protection systems are used, such as aluminum tape for the sensor.
What you must consider is the metal bumper or special paints, are not capable of generating interference D4P, as with other sensors analogue sensors
Because D4P is designed in that way. It has no special meaning the rear speaker sounds when the vehicle is moving forward, as it might attract undue alerts. The objective of the sensor system to alert the driver of a possible collision with an obstacle when moving in one direction. If it does not move in that direction does not make sense alert.
Note that if the vehicle incorporates front and rear sensors when the vehicle moves , it is normal that the system only alerted acoustically front.
However if the vehicle is moved back, then the front speaker will sounds if detect a close obstacle, because in the backward movement the front area of the car can be approximated to a barrier to turn the vehicle.
In both cases, however the LED DISPLAY will keep to you informed about the distance to the obstacle and also by the vehicle OEM screen, if it is within the GROUP III compatibility. Check the behavior diagram manual for further information.
Note that in some cases some concepts of the logic of the sensor system manufacturer original D4P override. An example of this type occurs in BMW vehicles compatible with the GROUP III. In this case if there is an obstacle in the detection and rear vehicle moves forward the rear speaker sound. Since the speaker is controller by the radio’s own vehicle.

If the system is automatically activated when it is moving, it is because it has detected an obstacle closer than one meter to the front bumper. This system is referred to D4P “System Auto Detect ” and no other devices on the market that incorporate it. Has more information on its operation on the [PRODUCT / INTELLIGENT OPERATION ] .
This system will help in the following scenarios:

When the D4P button LED light is blinking, the system is warning that there is an alert condition that may be related to the following reasons:
If a sensor is defective, the D4P control unit emit a series of flashes of the LEDs in RED and GREEN incorporated, the control unit indicates the number of faulty sensor. Note that if you have left off all sensors, each LED will blink four times, indicating that the high level sensor is detected. If you change the sensor and the error persists, sure the problem is the cable or which are not seen are rear sensors, check that they are not active.
In addition if you connect a LED display to the area with fault sensor, the LED display will show for 2 seconds the total number of faulty sensors (E4 = all sensors) and the location of the fault (red LED of display)
It is very difficult for a factory sensor is faulty. The sensors are checked one by one in manufacturing and also after a test one by one before going to market.
If the Digi4Park® LED display show a message during the first two seconds after activation of the type [Ex], indicates that there is an error in a sensor. The “x” is replaced by the number of faulty sensors in total, to indicate the position of the faulty sensors on each side of the vehicle the four red LEDs that are next to the orange digits show the fault sensor. So what red light will means “damaged sensor”. The message disappears after 2 seconds.
Digi4Park® can operate with only one active sensor. Check the installation manual for more information on this topic.
In this case there can only be two reasons why the rear sensors are not displayed or not work:
If the blue light of D4P control unit is blinking and after a short time it switch off, is that it is not detecting the vehicle CAN BUS. If it D4P control unit can not detect the CAN the system will power to off. It’s an interesting way to check if you have connected the CAN BUS backwards. Check your connections. Remember that some models have the connection information directly into the CAN BUS Vehicle record database Digi4Park® in the web.
If red or green lights that are on the control unit D4P blink, an error in one of the system sensors. An error may be due to 2 reasons:
If the LED flashes 4 times, it is likely that the wiring is not connected, as by default D4P first reports of the absence or disconnection of sensor-order (4) and then progressively as it is finding successive 3, 2, 1.
To update the database with support vehicles and D4P functions will need to disconnect your D4P control unit from the vehicle, a USB to Mini USB wire , software upgrade, and patch file. All these elements except the cable can be downloaded from the website of Digi4Park® section [SUPPORT / SOFTWARE & UPDATES]
If one of the sensors is damaged your system you should report any of these ways:
Refer to the installation and contact your installer or dealer.
