Vehicle-specific module service
JLR replacement module configuration is provided as a vehicle-specific service. JLR replacement module configuration matches a compatible control unit to the vehicle specification after the original fault is proven.
About JLR Replacement Module Configuration
A replacement module may need software, CCF data, security alignment, initialisation or calibration before it can operate correctly. A matching connector or partial part number does not prove compatibility.
The original unit, full vehicle scan and proposed replacement are compared before programming. This reduces the risk of transferring the wrong configuration or masking a wiring fault.
What this service includes
- Original fault and circuit confirmation
- Part-number, hardware and software comparison
- Security and previous-use status checks
- Backup of accessible coding and CCF data
- Supported configuration or programming
- Network scan and affected-function validation
The final scope is confirmed before work begins. No feature, key or module is treated as compatible solely because it looks correct or appears in a generic parts list.
When this service may be suitable
- A BCM, KVM, RFA or supported module has been replaced
- A new module communicates but functions are missing
- Configuration mismatch codes are stored
- A used module needs suitability assessed
- The original unit is available for data comparison
These signs help route an enquiry, but they do not replace diagnosis. Two vehicles showing the same message can require different work because their platform, software, equipment and failure history differ.
Compatibility and diagnostic checks
- Original and replacement part numbers
- VIN, market and equipment specification
- Module security state and software level
- Power, ground and network integrity
- Calibration or online programming requirements
We preserve the complete diagnostic evidence, including the reporting module and DTC suffixes. Low voltage, damaged wiring, lost network communication or missing hardware must be resolved before programming is presented as the answer.
How the mobile service works
- Identify the vehicleConfirm the registration, VIN, exact model, year and fitted security or control-module platform.
- Verify authority and compatibilityCheck ownership where security work is involved and prove the proposed key, part or configuration is suitable.
- Diagnose before changing dataTest battery condition, communication, relevant wiring and the original fault evidence.
- Complete the agreed serviceWe verify the module and underlying circuit, preserve accessible original data and apply the supported configuration route. The vehicle is then rescanned and every affected function is tested.
- Validate the resultRepeat the original operating conditions, scan the vehicle and test every affected function before handover.
What to send with your enquiry
Vehicle details
- Registration and VIN where available
- Jaguar, Land Rover or Range Rover model
- Exact model year and postcode
- Whether the vehicle starts and can be moved
Fault or service details
- Number of working keys
- Exact warning wording and full DTC suffixes
- Relevant part numbers or fitted retrofit details
- Recent battery, wiring, module or key work
Photos of the current key, scan report, module labels or dashboard message can prevent the wrong part or service being selected.
Frequently asked questions
Can any used module be configured?
No. Some modules remain security-locked or contain incompatible hardware and software.
Should the original module be kept?
Yes where safe. It may contain coding, identity or diagnostic evidence needed to configure the replacement correctly.
Does configuration include calibration?
Not always. Cameras, radar, steering and other systems may require a separate physical calibration procedure.
