Autel Corner Reflector for Radar-Based ADAS Calibration (BSD, Rear Collision)

The Autel Corner Reflector (SKU: AULCSC0802-01) is a passive radar calibration target designed for static calibration of rear and side radar-based ADAS systems — including Blind Spot Detection (BSD), Rear Cross-Traffic Alert (RCTA), Rear Collision Warning (RCW), and Lane Change Assist (LCA). If your shop touches rear bumpers, rear radar sensors, blind-spot modules, or rear quarter panels in collision repair, this is the target component you need to complete those jobs correctly.

What a Corner Reflector Does and Why It Matters

Camera targets are flat printed panels. Radar targets are different. A corner reflector uses a precisely angled metallic trihedral geometry to bounce radar waves directly back to their source — the vehicle's radar ECU. This return signal is what the ECU measures during calibration: signal strength, angle of incidence, and detection range. Without a proper corner reflector positioned at the OEM-specified lateral and rearward distance from the vehicle, the radar ECU cannot complete its calibration routine. The system will not accept a calibration complete command. The job is not done.

This matters practically: a technician who replaces a rear bumper cover, swaps a blind-spot sensor, or performs any repair involving the rear quarter panels is legally and professionally responsible for restoring those safety systems to factory specification. A road test does not satisfy that requirement. A documented static calibration with the correct target does.

Which ADAS Systems Require This Target

• Blind Spot Detection (BSD): Rear-mounted radar sensors that monitor adjacent lanes. Any sensor R&R, bracket damage, or bumper removal requires static recalibration.
• Rear Cross-Traffic Alert (RCTA): Detects crossing traffic when reversing. Calibration required after any rear bumper or sensor work.
• Rear Collision Warning (RCW): Monitors closing vehicles from behind. Recalibration required after rear-end collision repairs.
• Lane Change Assist (LCA): Uses the same side/rear radar array as BSD on many platforms. Calibration of one often requires calibration of the other.

How This Fits the Autel CSC Calibration System

The AULCSC0802-01 corner reflector is an accessory component for the Autel CSC (Calibration Standard Components) frame system. The CSC frame provides the structural rail and positioning hardware; vehicle-specific targets — including this corner reflector — attach to or position relative to that frame according to OEM calibration procedures. The calibration routine itself runs on a MaxiSYS tablet (Ultra, MS909, MS919, or Elite II) with Autel ADAS software loaded. The software walks the technician through positioning requirements, runs the ECU communication, and confirms calibration acceptance.

Note: this corner reflector is for rear and side radar calibration only. Front radar (Adaptive Cruise Control/ACC) calibration uses a separate target. If your shop handles both front and rear radar work, confirm with us which additional targets you need for your vehicle mix.

Who Needs This in Their Shop

• Collision repair shops: Any rear-end hit involving the bumper cover, fascia, or rear quarter panels almost certainly requires BSD/RCTA recalibration before delivery.
• Independent mechanical shops: Rear bumper R&R for any reason — trailer hitch installs, sensor replacements, cosmetic repairs — triggers radar recalibration on equipped vehicles.
• Dealership service departments: Warranty and goodwill repairs involving rear radar sensors require documented static calibration.
• ADAS calibration specialists: If you are positioning your shop as an ADAS calibration center, rear radar coverage is a requirement, not an option.

Calibration Workflow Overview

• Step 1: Complete all mechanical repairs. Confirm vehicle is on level ground, tires inflated to spec, and all rear panels are reinstalled.
• Step 2: Set up the Autel CSC frame and position the corner reflector at OEM-specified lateral offset and rearward distance from the vehicle (retrieved from Autel ADAS software by make/model/year).
• Step 3: Connect MaxiSYS tablet, navigate to ADAS calibration for the target system (BSD, RCTA, etc.), and follow the guided procedure.
• Step 4: The radar ECU measures the reflected signal from the corner reflector, validates against factory parameters, and confirms calibration complete.
• Step 5: Print or save the calibration report for the repair order.
