Pre-installation of Blind Spot Sensor (code J1V) package includes:

• 2 Blind spot sensors
• 2 Plastic brackets
• 2 Covers
• 8 Screws (connect plastic bracket with cover)
• Wiring harness interface in the driver seat box

For more information:

• Visit Upfitter Portal (www.UpfitterPortal.com) for 3D CAD data
• Review Sprinter Body and Equipment Guideline (BEG) section 8.9.4 ‘Blind Spot Assist/ Rear Cross Traffic Alert (RCTA)/ Exit Warning’

Position Requirements

Measured from the reference point of the sensor, the blind spot sensor must be placed:

• At most 6250 mm from the wheel center of the front axle
• At most 1650 mm from rear end of vehicle body
• At least 350 mm from the ground
• At most 1000 mm from the ground

Mounting Information

To install the blind spot sensors to the box body side walls, the upfitter must:

• Make a cutout at appropriate position based on the provided specifications on each side of the box body side walls
• Cutout dimensions: approximately 5.9 in X 5.9 in (150 mm X 150 mm)
• Create a metal bracket for each side that holds the sensor at 10.5° +/- 1° from the side wall
• Surface that is angled at 10.5° +/- 1° (e.g. metal bracket) must be mounted perpendicular (90° +/- 1°) to the ground
• Mount the metal bracket with the sensor and cover to the side wall with protruding part facing the vehicle rear
• Sensor plug must point downward
• Protect against water intrusion and corrosion
• Water drops should not fall onto the sensor as this could interfere with the sensor's ability to detect objects

Upfitter Bracket

The upfitters must design and manufacture their own bracket that will hold the blind spot sensor assembly and fit to the design and the layout of box body side wall. Following are the guidelines for designing the upfitter bracket:

• Ensure that the bracket is made out of metal with 0.08 in (2 mm) thickness to allow the plastic bracket clips to pass through
• Include three threaded holes to fasten the metal bracket onto the Mercedes-Benz plastic bracket. Part number for screws is A0059907612.
• Include two small rectangular holes for clips from the Mercedes-Benz plastic bracket. See Appendix for measurements for hole patterns.
• Include a gap at the bottom of the bracket for the wiring to sensor to pass through
• Account for water drainage in the case any liquid leaks into the bracket assembly

Illustration of an example design for the upfitter-designed metal bracket, showing screw holes and clips. For reference, an example design of the metal bracket is available on the Upfitter Portal. Please see under ‘3D CAD Data’ page on the Upfitter Portal.

Assembly Instructions

1. Assemble all the ex-factory Mercedes-Benz parts together. Mount the sensor onto the plastic brackets and affix the plastic bracket to the plastic cover. Note that screws have tightening torque of 1.6 Nm +/- 0.2 Nm.
2. Mount the metal bracket designed by the upfitter onto the cutout (~ 5.9 in X 5.9 in) on the box body side wall.

3. Locate the mating connector to the sensor plug and cover the blind spot sensor wiring harnesses to protect against sharp edges and/or debris.
4. Slide the mating connector wiring through the metal bracket mounted on the side wall panel. Note that the wiring needs to go from inside of the side wall panel to the outside of the panel.
5. Connect the mating connector to the plug of the blind spot sensor located on the outer surface of the side wall panel. Note that the sensor plug should face down.

6. Fasten the blind spot sensor assembly to the metal bracket from inside the side panel. Note that screws have tightening torque of 1.6 Nm +/- 0.2 Nm.

Mounting Restrictions

Please observe the following requirements when installing the blind spot sensors:

• When installing and testing the blind spot sensors, ensure that the workplace and the workers are equipped with ESD protection. Without such protections, the sensors may be damaged by electrostatic discharges.
• Blind spot sensors must be positioned symmetrically on the left and right side wall panels.
• Do not install any additional cover to the provided ex-factory blind spot cover. Do not cover the blind spot sensor.
• Radar cone of the sensor (in yellow) must not touch the side wall. Radar cone is included in 3D CAD data for blind spot sensor.
• Entire rear outer edge of the cover (see arrow) must be at least 0.08 in (2 mm) extruded out from the side wall outer-surface.

Diagram illustrating the mounting restriction where the rear outer edge of the cover must be extruded at least 0.08 in (2 mm) from the side wall outer-surface.

Please observe the following requirements when installing the blind spot sensors:

• Do not mount blind spot sensor on moveable surfaces (e.g. storage doors, slide-outs). Blind spot sensor must be mounted on a surface that is rigidly fixed on the vehicle body.
• No parts must be inside the radar cone, especially metallic parts. Do not install any parts projecting out in the direct line between the sensor and the rear of the vehicle. Any extruding parts that are attached perpendicular (90°) to the side panel and/or are round in shape can reflect the rays from the blind spot sensor back to the sensor.
• No attachments protruding from the surface wall (e.g. door handles, signal lights) may be installed between the sensor and the rear of the vehicle at a vertical angle of +/- 20° from the sensor reference point (see below image). Please see slide 4 for reference point position.

Please observe the following requirements when installing the blind spot sensors:

• No detachable parts may be mounted on the vehicle rear at area that is outside of 10° inward angle measured from at least 3.9 in (100 mm) into the side wall.

Paint for Plastic Cover

The ex-factory plastic cover will be delivered unpainted, so that the upfitters can paint the plastic cover to match the outer side wall panel of their upfitted vehicles. Please note that the paint coat structure must not exceed the following limits:

• A maximum of two color coats with a thickness of 591 μin (15 µm) each.
• With metallic silver, only one coat with a thickness of 591 μin (15 µm) plus one coat in white 591 μin (15 µm) thick are permissible.
• The material thickness must be homogeneous in order to prevent distortion of the radar waves.
• Specified thickness for unpainted covers: 0.098 in +/- 0.004 in (2.5 mm +/-0.1 mm), without paint

Electrical Connection – Driver Seat Box

Wiring harness for the blind spot sensor is located inside the driver seat box. This includes the connector, shown below, that must connect to the blind spot sensor.

Upfitters must acquire their own extension wires based on the length of the upfitted vehicle. Using the extension wires, connect the blind spot sensor connector in the driver seat box to the blind spot sensor mounted at the rear of the vehicle.

Electrical Connection - Sensor

The plug at the bottom of the blind spot sensor is shown below. Using extension wires, link the connector in the driver seat box to the connector on the blind spot sensor. The upfitter must protect the wires against sharp edges and/or debris.

Follow the pin information provided in the table when pinning to the sensor connector. Note that the wiring for the right side sensor differs from the wiring for the left side sensor.

Xentry – Software Coding

Once the blind spot sensors are installed, use Xentry Diagnostic Tool to activate blind spot sensor functions. If you do not have Xentry Diagnostic Tool, please visit your local dealer for the following steps.

1. Add option code OB2 ‘Activation of Blind Spot Sensor’ to VeDoc using Xentry.
2. Add appropriate O-codes based on the upfitted vehicle's dimensions for each of the following categories: Rear overhang, Vehicle width without mirrors, Mounting height, Mounting x-distance to the rear axle. Please see Appendix for all the available relevant O-codes.
3. Perform SCN coding on the following control modules:
   • B92/21 Outer right rear intelligent radar sensor system (IRS-HRA)
   • B92/24 Outer left rear intelligent radar sensor system (IRS-HLA)

No calibration needed after installation of blind spot sensor.
