Wade Sensing – OEM Water Depth Detection Retrofit

What This Retrofit Includes
- A pair of genuine Wade Sensing ultrasonic sensors that mount securely inside each front door mirror housing. These sensors send and receive high‑frequency sound pulses to measure water depth with millimetre accuracy.
- The dedicated Depth Detection Module (DBS module) that processes the sensor signals and communicates with the vehicle network. We mount the module in its factory‑designated location behind the instrument panel.
- A complete vehicle‑specific wiring harness that links the sensors to the DBS module and integrates with the Medium‑Speed CAN network. Every connector and terminal matches the original circuit diagram—no splicing, no adapters.
- Full software enablement using JLR Pathfinder. We update the Car Configuration File (CCF) to register the “Wade Sensing” feature and the DBS module. The touchscreen then presents the dedicated depth‑display interface and trigger points within the 4x4i menu.
- A rigorous water‑simulation test. We verify that the signal path functions correctly, the display updates in real time, and the threshold warnings activate at the manufacturer‑specified depths.
Compatible Land Rover Models
Wade Sensing is native to Land Rover’s advanced all‑terrain platforms. Vehicles that offered the option from the factory have the necessary mirror brackets and CAN‑bus architecture already in place. We source and install the complete hardware set for:
| Model | Supported Years |
|---|---|
| Discovery 5 (L462) | 2017 – 2026 |
| Range Rover (L460) | 2022 – 2026 |
| Range Rover Sport (L461) | 2023 – 2026 |
| Defender (L663) | 2020 – 2026 (with ClearSight mirror doors) |
We check your VIN to confirm that the door mirror harness and CAN gateway accept the new module. If your vehicle originally had power‑fold, heated mirrors, the upgrade proceeds without any physical modification to the door shells.
How the System Delivers Real‑Time Depth Data
Each mirror sensor emits an ultrasonic pulse downward. The pulse reflects off the water surface and returns to the sensor. The Depth Detection Module measures the time‑of‑flight and calculates the precise distance from the mirror to the water surface. Because the mirrors sit at a known height above the vehicle’s lowest point (typically the differential or exhaust), the module converts that distance into the effective wading depth. The result appears on the touchscreen with a clear numeric readout and a graphical water‑level indicator. As you drive forward, the system continuously updates the measurement, giving you instant feedback when the depth approaches the vehicle’s maximum wading capability. All processing happens within the DBS module, so the display remains smooth and responsive, exactly as the factory trained it.
The Retrofit Process Step by Step
- You place your order and provide your VIN. We procure the exact sensor kit, DBS module, and harness that match your Land Rover’s specification.
- Our mobile technician arrives with genuine parts and JLR‑approved diagnostic tools.
- We fit the ultrasonic sensors into your existing door mirror housings. The sensors clip into the reserved mounting brackets and connect to the new mirror loom that runs through the door conduit.
- We install the Depth Detection Module behind the dash, secure it on the factory bracket, and integrate the harness into the Medium‑Speed CAN network.
- We reconfigure the vehicle software with Pathfinder. The CCF update enables Wade Sensing, and the touchscreen software loads the water depth interface directly into your 4x4i menu.
- We test the system by simulating water surfaces at known distances. You watch the depth reading change in real time, and we confirm that the warning threshold triggers at the correct depth—giving you full confidence before your next off‑road adventure.
Why Choose LR‑Retrofit for This Upgrade
- Complete OEM integration – You receive the same sensors, module, and wiring that Land Rover fits on the production line. The touchscreen displays depth data without any third‑party overlay.
- No compromise on vehicle safety – The DBS module communicates via the dedicated CAN bus, leaving the original network architecture intact. All other driver‑assistance features—like blind‑spot monitoring and ClearSight ground view—continue to operate normally.
- Mobile convenience – We bring the entire installation to your home or workplace, eliminating the need for a dealership visit.
- Warranty‑safe procedure – Genuine parts and manufacturer‑approved software flashing preserve your vehicle’s warranty and future serviceability.
Important Considerations
Wade Sensing requires door mirrors that have the internal mounting bosses for the ultrasonic sensor. Most vehicles that had power‑fold mirrors from the factory already include these bosses. We confirm compatibility from your VIN before ordering parts. The retrofit adds no visible changes to the mirror exterior; the sensor hides behind the lower trim cap, and the mirror glass and housing remain unchanged.
The feature works seamlessly with the existing 4x4i screen and adds a dedicated “Wade Sensing” tile. When water depth reaches the pre‑set caution threshold, the system triggers a visual and audible alert. You gain the same real‑time confidence that original owners of high‑specification vehicles enjoy—without any clutter on the dashboard.
