2015-2016 Range Rover Sport Parking Module: 'Unavailable' Errors & Programming Guide
This guide covers the common failures, programming requirements, and replacement costs for the parking aid control module in the 2015-2016 Land Rover Range Rover Sport.
- Programming is mandatory for any replacement module (new or used) using Land Rover-specific diagnostic tools.
- The 'Parking Aid Unavailable' message is the most common symptom, but it can be caused by a simple bad sensor, not just the module.
- Before replacing the module, check for faulty sensors by listening for a faint clicking sound from each one.
- Always match the OEM part number from your original module to ensure compatibility.
Symptoms of a Failing Parking Aid Control Module
When the parking aid module begins to fail, your vehicle will provide several clear warnings. Ignoring them can lead to an increased risk of collision while parking.
- 'Parking Aid Unavailable' Message: This is the most common symptom. A message will appear on the instrument cluster, indicating the system has a fault and is disabled. 🎬 Watch: How to fix the Land Rover Park Aid Unavailable warning
- Flashing Park Assist Button: The light on the parking assist button on the dashboard will flash instead of staying solidly lit when the system is active. This flashing indicates a system fault.
- No Beeping or Visual Alerts: When reversing or approaching an object, the system will remain silent and may not show distance graphics on the main screen.
- Constant Beeping: In some cases, a faulty module or sensor can cause a constant, steady tone as soon as the system is activated, even with no obstacles nearby.
- OBD-II Fault Codes: A diagnostic scan can reveal specific trouble codes related to the module or sensors. Common codes include B1B50, B1B52, B1B53, and U0159, which point to a malfunctioning or failing module. Codes in the range of B1B44 to B1B4B often indicate a fault with a specific sensor, which can help pinpoint the problem.
Known Issues & TSBs for 2015-2016 Range Rover Sport
While the module itself can fail, problems with the parking aid system are often caused by external factors or software glitches.
Software Errors and TSBs
Land Rover has issued Technical Service Bulletins (TSBs) for parking aid issues. TSB LTB00860NAS2 addresses intermittent operation of the Park Assist system on 2015 Range Rover Sport models, where a maneuver might be canceled unexpectedly. The cause is identified as a software error, and the fix involves reconfiguring the existing parking aid control module using dealer-level diagnostic tools. This procedure does not require replacing any parts but is essential for restoring proper function.
Sensor and Wiring Failures
Often, what appears to be a module failure is actually a problem with one or more of the ultrasonic sensors in the bumpers. These sensors are exposed to the elements and can fail due to:
- Dirt and Debris: A layer of mud, snow, or even heavy rain can block a sensor and cause the system to report a fault. 🎬 Watch: Causes and fixes for blocked or unavailable Park Assist
- Physical Damage: Minor parking lot bumps can crack or dislodge a sensor, causing it to fail.
- Wiring Corrosion: The wiring and connectors for the sensors are located behind the bumpers and are susceptible to water intrusion, leading to corrosion and bad connections.
Pro Tip: Before condemning the control module, check the individual sensors. With the ignition on and the system active (in reverse), listen closely to each sensor. A healthy sensor will emit a faint, rapid clicking sound. A silent sensor is likely dead and is the source of your problem.
Programming and Installation Requirements
Warning: This module is not a plug-and-play part. It requires programming and configuration to work correctly with your vehicle.
Whether you install a new or used parking aid control module, it must be configured to your Range Rover Sport's specific Vehicle Identification Number (VIN) and optional features. The module needs to know how many sensors the vehicle has, whether it's equipped with a 360-degree camera, and other system-specific parameters.
This configuration process must be performed with a Jaguar Land Rover (JLR)-approved diagnostic tool, such as the JLR SDD (Symptom Driven Diagnostics) software. A Land Rover dealer or a qualified independent shop with the proper equipment can perform this service. Without proper configuration, the system may not produce any sound from the sensors or may not function at all. Some advanced aftermarket diagnostic tools may also offer this programming capability.

A used OEM module is an excellent, cost-effective alternative to a brand-new unit, provided you take a few precautions.
- Match the Part Number: Land Rover uses several part numbers for this module, including CPLA14C261AC, FW93-2C491-AB, and GX63-15C859-DG. While some numbers may be interchangeable or superseded, the safest approach is to match the part number from your original module exactly. The part number is printed clearly on the module's label.
- Inspect for Corrosion: The module is typically located in the rear of the vehicle, an area that can sometimes be prone to moisture. Carefully inspect the electrical connector pins on the used module for any signs of green or white crust, which indicates water damage. Do not buy a module with any signs of corrosion.
- Source from a Reputable Seller: Purchase from a seller that tests their parts and offers a warranty. This protects you in case you receive a defective unit.
- Factor in Programming Costs: Remember that you will need to pay for programming after installation. Contact a local dealer or specialist shop beforehand to get a quote for this service.
Cost of Replacement
The cost to replace a parking aid control module can vary significantly based on the parts source and labor rates.
| Item | Estimated Cost |
|---|---|
| New OEM Module | $350 - $500+ |
| Used OEM Module | $50 - $150 |
| Shop Labor (Installation & Programming) | $150 - $300 |
Note: Prices are estimates and can vary by location and supplier. Labor for just programming an already-installed module is typically around 0.5-1.0 hours.
Frequently Asked Questions (FAQ)
Does a used parking aid module need to be programmed?
Yes. Any replacement module, whether new or used, must be programmed and configured to your vehicle's VIN and specific options using a JLR-approved diagnostic tool. Without this step, the system will not function correctly.
Where is the parking aid module located on a 2015-2016 Range Rover Sport?
The rear parking aid control module is typically located in the rear of the vehicle, often behind the right-side luggage compartment trim panel. Accessing it requires removing some interior panels.
What causes the 'Parking Aid Unavailable' message?
This message can be caused by a faulty control module, a bad sensor, damaged wiring, or even just a dirty sensor. A diagnostic scan is the best way to determine the exact cause, but you can start by cleaning all sensors and checking them for the faint clicking sound that indicates they are working.
Can I replace just one bad sensor instead of the whole module?
Yes. If diagnostics confirm that only one sensor has failed, you can replace just that individual sensor. This is a much cheaper and simpler repair than replacing the entire control module. After replacement, the fault codes should be cleared.
