Bendix ESP and Wingman Collision Mitigation Troubleshooting Guide

Vertical Radar Alignment Check

This section details the procedure for checking and adjusting the vertical alignment of the radar unit.

1. Park the bus on a level surface. Ensure the air suspension is charged as it would be during normal operation.
2. Place the digital inclinometer on a horizontal section of the frame rail. Zero out the inclinometer.
3. Place the calibrated inclinometer against the front surface of the radar unit, ensuring it is in the same orientation as it was on the frame rail.
4. Verify that the inclinometer displays 0° (+/- 1.5°).
5. If no adjustment is necessary, proceed to the next section or page.
6. If adjustment is necessary, use a Torx T-20 Screwdriver. Rotate the top left adjustment screw on the forward-facing radar unit until the inclinometer display reads 0° (+/- 1.5°).
7. Re-cycle the ignition key.
8. If necessary, clear the Diagnostic Trouble Code (DTC) using Bendix ACom.
9. Proceed to the next section or page.

Visual Aid Description: A digital inclinometer device is shown, displaying 'LEVEL 0.55' with buttons for ON/OFF, TILT%, ZERO, and HOLD. An illustration of the radar unit indicates where to use a Torx T-20 screwdriver for vertical alignment adjustment. A critical note reads: "IMPORTANT: Do not adjust this stand-off!!"

Lateral Radar Alignment Check

This section outlines the steps for checking and adjusting the lateral alignment of the radar unit.

1. Select "OK" on the Driver Information Unit (DIU).
2. Using the arrows on the DIU screen, navigate to the menu: "Radar" then "Alignment Check", and press "OK".
3. A "Learned Alignment" indicator will be displayed. It is important to note that the system learns its true alignment over many hours of driving; this indicator does not necessarily mean something is wrong with the system.
4. If no correction is required (the display shows 0), proceed to the next section or page.
5. If a correction is required, the display may show a counterclockwise correction indicated by the number 5 in a circular arrow. Note that this correction may be in either direction and represented by any number.
6. Using a Torx T-20 Screwdriver, rotate the bottom right adjustment screw on the forward-facing radar unit five full turns counterclockwise.
7. Upon completion, select "Reset" and then "Exit" on the DIU.
8. Re-cycle the ignition key.
9. If necessary, clear the DTC using Bendix ACom.

Visual Aid Description: The DIU screen is depicted, showing "Learned Alignment 1.6°" and "Correction 5" with a circular arrow, along with navigation buttons "Reset", "Next", "Exit", and "OK". An illustration of the radar unit shows where to use a Torx T-20 screwdriver for lateral alignment adjustment. A critical note reads: "IMPORTANT: Do not adjust this stand-off!!"

Camera Mounting

This section provides instructions for mounting, removing, and replacing the camera unit and its bracket.

General Warnings and Preparation

WARNING: Whenever re-installing or replacing a camera (e.g., after a windshield replacement), the recommended position for the vehicle must be used. Failure to install the camera in the correct position can result in system Diagnostic Trouble Codes being set and system performance degradation.

Temperature Requirements: The ambient temperature must be in the range of 50-100° F.

Cleaning: Thoroughly clean the area of the windshield where the camera will be installed with a lint-free cloth and a 50-50 water/isopropyl alcohol solution. Make certain that there is no grease or contamination present and that the windshield is completely dry before installing the bracket.

Marking: Use removable tape or a non-permanent marker to indicate where the top of the bracket will be installed.

Bracket Installation:

1. Remove the protective film from the tape covering the adhesive on the bracket.
2. Using a small "torpedo" level, ensure the bracket is level.
3. Install the bracket on the glass, holding firmly with a minimum of 62 lb. (28.1 kg.) pressure for ten (10) seconds.
4. Wait at least twenty minutes before installing the camera. At this point, a 50% bond strength is created. The full bond between the bracket and windshield is achieved after 72 hours.

Visual Aid Description: A diagram illustrates measurements for camera bracket placement on the windshield: 7 1/8 inches down from the bottom edge of the rubber windshield seal, and 6 inches over from the center line of the windshield.

Camera Removal

CAUTION: Do not use a twisting action when releasing the camera tabs. Insert two medium-sized flat-blade screwdrivers into the slots at the lower corners where the camera and bracket meet, fully seating them. Then, gently pry by moving the screwdriver handles towards each other a small amount – push against the retaining clips to release the camera. Never twist the screwdrivers as the tabs may break! Replace the bracket if the tab is broken.

Visual Aid Description: A diagram labeled "Figure 13 - Camera Release" shows the two specific locations at the lower corners of the camera/bracket interface where screwdrivers should be inserted for removal.

Bracket Removal

The camera must be removed prior to this procedure. The preferred method for removing a bracket ideally requires two technicians. Using a heat-gun, one technician gradually applies heat to the outside of the windshield at the location of the adhesive, while the other gently applies a prying force to the bracket, being careful not to damage the windshield.

As soon as the ideal temperature is reached, the bracket will release. Allow the windshield to completely cool down before cleaning the glass and installing a replacement bracket.

When replacing brackets, use only replacements with the same part number or a direct superceding replacement number supplied by Bendix or the OEM. If you have questions, contact the Bendix Tech Team at 1-800-AIR-BRAKE (1-800-247-2725), option 2.

NOTE: Some OEMs may offer the windshield with the bracket pre-installed. Contact the dealer for more information.

Installing Camera into Bracket

To install the camera into the bracket:

1. Engage the top of the camera into the bracket. There are two channels in the camera that need to line up with the bracket housing; check to be sure that both sides engage into the bracket.
2. While maintaining the engagement at the top of the camera, rotate the rest of the camera body about that hinge point, towards the bracket.
3. When the camera and bracket meet, there are retaining clips built into the bracket that will snap into place, holding the camera in position.
4. IMPORTANT: Double-check that the camera is fully engaged into the bracket by verifying that the channel between them has the same gap all the way around. Pull gently on the camera to check that the tabs at the top and bottom are engaged and that there is no play.
5. Remove any tape or temporary marks made during the installation.

Visual Aid Description: Series of diagrams illustrate the camera installation process: engaging the top, rotating the body, and confirming the click of retaining clips. A visual warning "WRONG-TOO WIDE ❌" is shown, with instructions to verify the gap between the camera and bracket is consistent all around and to pull gently to ensure tabs are engaged and there is no play.
