The backup assist PDC system comes with 1 acoustic warning loudspeaker (buzzer, master device), 1 waterproof control unit (slave device) and 6 compact waterproof paintable
sensors. The sensors are configurable via the master device according to your preferences and bumper type (contact a qualified Service Center).
Sensors can be fitted all 6 on the rear bumper or split between the top and bottom (4 on the bumper and 2 at the top to detect high-level obstructions such as overhanging tree
branches, porches, low roofs, sign posts etc.).
1.1 - ACTIVATION: The buzzer activates automatically when ignition key is switched ON while the control unit activates only when reverse gear is engaged. Once powered, the
control unit carries out a complete operating self-diagnostic test and transmits data to the buzzer. If all 6 sensors are operative, 1 Beep will confirm activation otherwise, a deep error
tone (Bop) will sound followed by the number of beeps corresponding to the faulty sensor. From this moment on, communication remains active betweenthe 2 devices to monitor the
area behind the vehicle until reverse gear is disengaged.
a) Tow Bar/Rear Spare Tire Configuration
When a vehicle has a tow bar or a rear spare tire, the control module can be configured to push out the impact detection zone past the accessory. The control module must be
configured by a qualified Service Center.
CAUTION: OBSTACLES BETWEEN THE BUMPER AND THE NEW STOP ZONE WILL NOT BE DETECTED.
b) Trailer Recognition
See OPTIONAL CONNECTIONS par.10.1.
c) Bike rack detection
See OPTIONAL CONNECTIONS par.10.1.
1.2 - OBSTACLE DETECTION
During a reversing maneuver, detection of obstacles is signalled by the buzzer with an audible proximity warning which becomes a continuous solid tone when the preset minimum
safety distance (STOP zone) is reached.
1.3 - SENSOR DETECTION INFORMATION
Certain conditions may affect the ability of the sensor to correctly detect obstacles:
1. Presence of human beings, animals or small obstacles or objects/materials with low reflectance might not be detected by the parking system.
2. In case of heavy rain/snow the parking system might give an audible alert even if no obstacles are present: this does notnecessarily indicate that the PDC is defective.
3. If the sensors are covered with mud, ice or snow (normal function resumes after cleaning or defrosting).
4. An extremely bumpy road or an incline, gravel or grass.
5. Vehicle horns, motorcycle engines, air brakes of large vehicles or other loud noises producing ultrasonic waves.
6. Heavy rain or splashes on the sensors and water puddles.
7. Obstacles located below the bumper will not be detected when they are in close proximity.
1.4 - SENSOR FAILURE INDICATION
When ignition is turned ON and reverse gear is engaged, the system provides an instant, automatic, self-diagnostic function. If all the sensors are operative, 1 Beep will confirm
activation. If one of the sensors is faulty or disconnected, a deep error tone (Bop) will sound followed by the number of beeps corresponding to the faulty sensor
The cycle will repeat
until all faulty sensors have been signaled. 2 Bops will confirm the end of the self-test cycle. The system will exclude any faulty sensor and keep the others active. The following is an
example of error indications:
Sensor 1 inoperative => 1 Bop + “1 Beep” + 2 closing Bops.
Sensors 1 and 2 inoperative => 1 Bop + “1 Beep” + 1 Bop + “2 Beeps” + 2 closing Bops.
1.5 - BASIC MAINTENANCE TIPS
When cleaning the sensors take special care not to scratch or damage the surface:carefully clean the sensors with a soft cloth.
In car washes which use steam jet or high-pressure washers, keep the nozzle at least 10 cm away from the sensors.

Sensors and adapters can be spray painted before assembly to match the color of the vehicle (optional). To spray paint proceed as follows:
1. Use isopropyl alcohol to clean the sensors and the adapters and let dry. Avoid touching the cleaned surfaces.
2. Insert the selected adapters in the supplied cardboard template:
Inner adapters fully insert into the cardboard template slots from the top side.
Outer adapters => press halfway down the slots, up to the side tabs, from the top side.
3. The sensors must be inserted in the slots from underneath the cardboard. For a perfect spray-paint finish, we recommend turning down the black silicone seal
around the sensor head before inserting the sensor into the slots (paint might not adhere to the silicone).
4. Fold the cardbox template into a box. Spray paint the sensors and the adapters and let dry thoroughly before assembling.
NB: Too much spray paint can impair the sensors performance.

System performance will depend on the correct positioning and angling of the sensors.
1. Accurately calculate and mark the sensor positions on the bumper.
2. Remove the bumper and make sure there are no obstructions that may hinder the fitting of the sensor heads and the control unit (ECU).
3. Use a small diameter bit to drill pilot holes for each sensor.
4. Finish the holes to the proper diameter using a cone drill bit that matches the diameter of the selected adapters.
Determine the correct mounting height and position to achieve the best detecting angle and distance (the figures shown below are purely indicative).
Installation and connections should only be done by qualified personnel.
Disconnect the negative battery terminal before doing any electrical work.
Some bumpers have factory markings on the inner side; before drilling any holes, make sure they correspond to the recommended positions.
Some bumpers require correction adapters around the sensors to obtain the proper fitting angle.

The PDC kit is directly Plug & Play connected as follows:
1. Connect the 6 wires coming out of the control unit to the 6 sensors (the longest wires to the sensors at the opposite end of the control unit).
2. Connect the connector coming out of the control unit to the corresponding reverse lightconnector.
10.1 – OPTIONAL CONNECTIONS:
1. BROWN wire: by connecting this wire to the radio MUTE, volume is temporarily excluded or reduced when an obstacle is detected.
2. BLUE wire: by grounding this wire (wire can be hooked up to an optional toggle switch), rear sensors can be disabled when towing. The system can also be made to
disable automatically by connecting the trailer plug (if a free pin is available for electrical ground).
3. YELLOW wire: by grounding this wire (wire can be hooked up to an optional toggle switch), the impact detection zone can be pushed out past the bike (minimum safety
distance (STOP zone) is pushed out approx. 1m). Bike rack mode must be selected before engaging reverse gear. When reverse gear is engaged, 3 audible warnings
(Beep-Bop-Beep) will confirm that the bike rack option is enabled. These beeping tones will be followed by the 2 activation tones.
CAUTION: OBSTACLES BETWEEN THE BUMPER AND THE NEW STOP ZONE WILL NOT BE DETECTED.
10.2 – CHECK AFTER INSTALLATION
ATTENTION: Make sure there are no other conflicting Master devices in use nearby.
1. Reconnect the negative battery terminal.
2. Turn ignition key ON and engage reverse gear. Activation will be confirmed by a short Beep.
3. Test the sensors one by one for detection by moving different obstacle simulators in front them.
Distances and detections are approximate because ofthe position, size and shape of the objects. For a more accurate detection, test the sensors by placing
the objects at different angles of the sensors field of view.
If needed, the sensor sensitivity can be modified (see configuration table).
4. If the parking sensors are working correctly, secure the bumper in place.
