Who Requires Or Recommends MIG Brazing? UPDATE

Posted on 25 November 2020

Non-SRS Wiring Repairs: Mercedes-Benz

Posted on 17 September 2019

What is a non-SRS wiring repair? It is the repairing of an electrical component that is not part of the supplemental restraints system circuit (usually identified by yellow wire looms). As technology increases on vehicles, so does the number of components that utilize electricity. Many of the sensors and modules are becoming smarter and more sensitive. If the wire is too long, the wrong gauge, or spliced in the wrong location it can cause malfunctions in the components that it’s powering. Many OEMs have different restrictions and guidelines for repairing wiring that does not control SRS components. On the other hand, there are OEMs that don’t allow wiring repairs at all, so full harness replacement is the only option.

Bumper Cover Repair With ADAS: Mercedes-Benz

Posted on 16 May 2019

A simple bumper repair on a modern vehicle may not be as simple as it seems. New technologies like blind spot monitoring, adaptive cruise control, and other advanced driver assistance systems (ADAS) utilize sensors behind the bumper covers. The ability for these sensors to be able to see clearly, normally requires special caution when considering a bumper repair. Many OEMs have different levels of warnings when it comes to repairing bumper covers with ADAS. So, what does Mercedes-Benz say on the subject?

Additional Calibration Requirements: Mercedes-Benz

Posted on 21 July 2017

The addition of the OEM Calibration Requirements Search to the RTS portal was a big step for the collision industry. While this new feature has been well received, there has been some confusion about what is included in the search tool. The OEM Calibration Requirements Search is designed to provide information on the calibration requirements that are needed for vehicles equipped with advanced driver assistance systems (ADAS). This includes systems such as adaptive cruise control, lane keep assist, and collision braking.

It does not include occupant classification systems (OCS), steering angle sensors, battery disconnects, or other calibrations/initializations required, when not related directly to ADAS. Let’s take a look at what additional items may require calibrations/initializations on Mercedes-Benz vehicles.

Structural Sectioning Procedures: Mercedes-Benz

Posted on 28 June 2017

Ask I-CAR receives many technical inquiries referring to sectioning. The collision repair industry wants to know where can you section, does the OEM have a sectioning procedure, and where can I find the sectioning procedure? Most OEMs allow sectioning to outer body panels and the front and rear rails. Sectioning reinforcements is not as common, as most reinforcements are replaced at factory seams.

Parts are made from various materials including HSS, UHSS, aluminum, and carbon fiber. These parts also have complex designs to collapse or transfer collision forces in a specific manner. Introducing a sectioning joint to many of these parts will alter how the part reacts to those collision forces. For this reason, sectioning a part is only allowed if supported by vehicle maker repair information. Let’s see what Mercedes-Benz says about structural sectioning.

Corrosion Protection Guidelines: Mercedes-Benz

Posted on 7 June 2017

A key factor in collision repair is making long-lasting repairs. When a vehicle is repaired, many areas of corrosion protection are disturbed. This creates corrosion hot spots, that left untreated will lead to corrosion, and potentially a repair failure. However, there are certain precautions that can be taken to safely and properly restore the corrosion protection throughout the repair process. OEMs often give specifications on restoring corrosion protection. These specifications generally include seam sealer, adhesives, foam fillers, and cavity waxes. Let’s take a look at what Mercedes-Benz says.

Posted on 11 May 2017

Have you noticed anything different looking on new vehicle grilles? If you have, you may have thought what is that strange looking flat spot? Sometimes this flat area is somewhat hidden by a manufacturer emblem. Other times it’s integrated into the grille itself, including grille lines. Let’s take a look at this new design element and what it’s hiding.

Awareness of Changing Refrigerant Types

Posted on 20 April 2017

You may have noticed that A/C refrigerant on many new vehicles has started to change. For many years, OEMs used R134a. However, government mandates require OEMs to phase out R134a by the year 2021. This left OEMs scrambling to find a replacement. Many US OEMs chose to use R1234yf to replace R134a, but there are some OEMs that have chosen a different route. Let’s take look at these new refrigerants.

Weld-Through Primer Guidelines: Mercedes-Benz

Posted on 3 April 2017

Weld-through primers are generally a zinc-based product that is applied to the mating surfaces prior to welding. Corroding zinc forms zinc oxide, which protects the steel. This is called sacrificial corrosion. For a quality weld to be made it’s required that the weld-through primer be removed from the direct weld zone before welding the joint, when MIG welding. Many OEMs have a position on when and how to use weld-through primer or when it shouldn’t be utilized. Let’s see what Mercedes-Benz recommends and where this information can be found.

Battery Disconnect Considerations

Posted on 21 February 2017

When a damaged vehicle enters a collision repair facility, many times the repairs require the battery to be disconnected. Operations such as welding, SRS repairs, engine work, and body panels being open for extended periods of time, can all require that the battery be disconnected. At one time the radio presets would be written down before the battery was disconnected and programmed after the battery was reconnected. However, today many OEMs have special precautions or steps that need to be taken when disconnecting the battery. Let’s take a look at what some OEMs require when disconnecting the battery.

Mercedes-Benz Glass Replacement Requirements

Posted on 23 November 2016

The role of the windshield is a lot more complex than simply allowing a view of the road ahead. It is considered a structural part of the vehicle as it contributes to the strength of the roof and A-pillars. The windshield helps to manage collision energy and has become an integral part of several advanced safety systems.

It is commonly asked, "What is required when replacing a windshield?" With this question in mind, we will be presenting a series of articles that highlight some of the requirements from the various OEMs. As always, it is important to read through each vehicle-specific procedure to ensure a complete, safe, and quality repair.
