01. Primary Dimensional Allocation & OEM Interfacing
This rear-aperture signaling hardware is engineered exclusively around the structural layout of the 2024–2026 BYD Yuan Up (ATTO 2) platform. Serving as a full-depth physical replacement for factory components SC3E-4135100A (driver side) and SC3E-4135200A (passenger side), the units fit natively into the lower bumper trim boundaries. By using inverted CAD modeling of the factory rear fascia, the mounting tabs align with the chassis receiver tracks to prevent panel-margin gaps, ensuring the compact EV maintains its intended aerodynamic styling and clean rear profile immediately following installation.
02. Asymmetrical Optoelectronic Configuration & Safety Redundancy
The hardware configuration treats the left and right bumper recesses as distinct functional zones to meet specialized lighting requirements. The left-hand module integrates a solid-state LED assembly that serves as an active, high-penetration rear fog lamp to increase visibility through heavy rain, road spray, or urban smog. Concurrently, the right-hand module operates as a non-powered retroreflective unit featuring a dense micro-prism lens matrix. This intentional asymmetry provides a balance of active illumination and zero-power passive marking, keeping the vehicle visible even during unexpected electrical outages.
03. Material Passivation & Environmental Isolation Standards
To withstand long-term exposure to the elements, the outer lenses are extruded from automotive-grade PC polycarbonate layered with a permanent UV50+ photolytic stabilizer to block solar yellowing and surface cracking. This lens structure is hot-glued to an injection-molded ABS housing to form an IP67-certified environmental barrier. This complete seal protects the internal electronics and reflective layers from high-pressure car wash nozzles, road salt mixtures, and moisture pooling across an operating temperature range of -40°C to +85°C.
04. Terminal Harness Integration & Electrical System Isolation
The driver-side active lighting unit features a factory-keyed plug designed to connect directly into the vehicle's native auxiliary wiring loom. This plug-and-play design allows for a non-destructive installation that avoids wire splicing or adding aftermarket load resistors. By maintaining factory current limits and keeping the passenger-side reflector completely mechanical, the entire replacement set remains isolated from the vehicle’s low-voltage CAN bus diagnostics, eliminating the risk of dashboard warning lights, error codes, or battery drain.
Technical Bulletin: BYD Yuan Up (ATTO 2) Bumper Module Deployment
Stage I: Pre-Assembly Cavity Decontamination
Prior to component integration, ensure the vehicle's low-voltage electrical system is completely dormant to prevent localized circuit faults. Thoroughly cleanse the lower bumper retention apertures using an isopropyl alcohol solution to dissolve road film, salt residues, and debris. A pristine receiver channel is mandatory to guarantee that the multi-point mechanical tabs engage at their engineered friction thresholds without structural interference.
Stage II: Asymmetric Extraction Protocol (Left vs. Right)
Left Active Lumen Cavity: Locate the primary electrical junction behind the left bumper fascia. Depress the locking tang on the factory wiring connector to isolate the harness. Using a non-marring nylon pry tool, apply outward leveraging force along the peripheral seam to release the internal retention clips, then extract the weathered fog lamp housing.
Right Passive Reflector Module: Since the passenger side contains no electrical components, bypass the harness isolation step. Direct the pry tool to the lateral edges of the right aperture, disengage the mechanical clips from the bumper receiver track, and pull the unit straight out.
Stage III: Dual-Nature Insertion & Terminal Interfacing
Active Port Integration (Left): Guide the new LED assembly into the left bumper housing until the indexing alignment studs seat firmly into the factory receiver slots. Apply distributed palm pressure to engage the lock tabs. Once mechanically secure, plug the factory-keyed terminal harness into the integrated socket until the water-sealed locking tab locks into place, restoring the circuit's original continuity.
Passive Port Integration (Right): Align the retroreflective module with the right-side bumper channel. Press firmly across the lens face to engage the snap-lock tabs, ensuring the component sits flush with the native bumper styling line.
Stage IV: Photometric Validation & Tolerance Audit
Energize the vehicle’s auxiliary power circuits and activate the rear fog control switch to verify the solid-state LED’s luminous flux output. Perform a physical alignment audit around the perimeter of both components; the localized panel-margin gaps must be uniform and zero-tolerance. Because this deployment strategy avoids the use of secondary liquid adhesives, the mechanical clip-on system achieves immediate load-bearing stability, allowing the vehicle to return to fleet service without a cure-time delay.
Customer Care & Warranty Standards
01. Pre-Shipping Verification & Order Protection Policy
To guarantee an absolute transaction standard for every BYD Yuan Up (ATTO 2) owner, our logistics team executes a rigorous structural verification process prior to dispatch. We cross-reference your specific regional model variations to prevent delivery errors and ensure complete alignment with your procurement intent. If you have any questions regarding your order before it ships, you can upload clear imagery of your current vehicle configuration directly through our merchant portal, allowing our customer care team to perform a specialized verification check and secure your purchase.
02. Asset Preservation & Daily Operational Guidelines
We prioritize the long-term aesthetic and functional value of your vehicle accessories. To maintain the original surface luster and optical clarity of your new components over years of daily exposure, we recommend standard cleaning using neutral soaps and non-abrasive microfiber cloths. During vehicle detailing or automated maintenance cycles, avoid directing localized pressure washers or concentrated chemical solvents toward the rear bumper accessories. This proactive care safeguards the housing integrity from premature weathering and keeps your vehicle looking pristine.
03. Comprehensive Manufacturer Warranty & Support Framework
Every component set is backed by a dedicated 6-month limited warranty that secures your investment against verified manufacturing anomalies, including premature lens discoloration or material structural defects under standard operating conditions. This protection framework focuses entirely on product quality and hardware exchange, excluding any secondary labor costs or auxiliary vehicle service fees. If you experience any issues with your set, our professional support division is fully reachable to provide step-by-step guidance, issue resolutions, or expedited hardware replacements.
