JET‑Pro JLR Engineering Tool – Diagnostic Coding

Full‑stack engineering diagnostic & coding platform for Jaguar Land Rover technicians. The JET‑Pro Engineering Tool combines diagnostic data acquisition with authorised coding capabilities, giving workshops a single solution for fault‑finding, parameter verification and approved configuration changes.

Product Overview

The Engineering Tool is a **modular suite** that integrates:

• Real‑time diagnostic data capture (live sensor streams, CAN‑bus frames, DOIP traffic).
• Advanced fault‑code analysis – includes JLR‑specific Extended Diagnostic Trouble Codes (EDTC).
• Configuration editing (CCF/CCS) under strict OEM‑approved edit‑rights.
• Exportable reports (PDF, XML) that can be attached directly to the JLR Service Portal.

Key Technical Features

• Unified interface for diagnostics and coding – switch between “Diagnostic” and “Coding” tabs without leaving the application.
• Support for **all JLR model years 2017‑2025** (auto‑detects ECU firmware version).
• Secure PKI‑based authentication with the JLR Service Cloud – each coding session is signed and logged.
• Built‑in **Safety Verification Engine (SVE)** that checks for conflicts before any write operation.
• Customisable “**Workflows**” – technicians can save a series of diagnostic steps and coding actions as a reusable template.
• Integration with popular workshop management systems (RSM, Autodata, etc.) via REST‑API.

Typical Workflow

1. **Connect** the approved JLR VCI to the vehicle.
2. **Launch** the Engineering Tool – select “Diagnostic” to read live data and retrieve fault codes.
3. **Analyse** the data; if a configuration‑related fault is identified, switch to the “Coding” tab.
4. **Load** the current CCF, review the relevant parameters, and apply only those flagged as “editable”.
5. **Commit** the change – the tool automatically signs the payload, uploads it, and generates a Diagnostic‑Coding Report (DCR).
6. **Close** the session – the DCR is stored in the workshop’s service record and can be sent to the JLR Service Portal for warranty or compliance purposes.

Use Cases

• **Fault‑code isolation** – combine live data with coding verification to pinpoint module mismatches.
• **Retrofit validation** – verify that newly installed components are correctly represented in the ECU configuration.
• **Warranty & recall support** – produce audit‑ready reports that satisfy OEM requirements.
• **Technical training** – teach new technicians a unified diagnostic‑coding workflow.
• **Dealer‑level feature activation** – safely enable optional equipment after a sale.

System Requirements

• Windows 10 / 11 (64‑bit), 16 GB RAM recommended, i5 ≥ 2.5 GHz processor.
• Dedicated diagnostic laptop (Panasonic CF‑54, Dell Latitude 7420, or equivalent).
• JLR DoIP VCI (firmware ≥ v3.5) **or** SDD VCI – both sold separately.
• Internet connection for licence activation, cloud authentication and OTA updates.

Installation & First‑Run Steps

1. Download the JET‑Pro_Engineering_Tool_Setup.exe from your lr‑retrofit.com account.
2. Run the installer – it will place the core engine, the diagnostic modules and the coding database (covers 2017‑2025).
3. Enter the licence key emailed to you; the software validates the token with the JLR Service Cloud.
4. Connect the approved VCI, launch the application and log in with your dealer credentials.
5. Run the “Initial System Scan” – the tool automatically detects ECU versions and loads the matching CCF schema.
6. Begin a “Diagnostic Session” → review live data → switch to “Coding” when required.

Support, Updates & Warranty

Each licence includes 12 months of technical support (phone + email) and **unlimited software updates**. Updates are delivered via the built‑in “Update Manager” and include new vehicle models, bug‑fixes and security patches. A 90‑day money‑back guarantee is offered if the tool does not meet the advertised specifications for your vehicle range.

Compliance & Safety

The Engineering Tool complies with JLR’s Technical Service Bulletin 2024‑07, which mandates that any coding operation be accompanied by a signed audit record. The built‑in Safety Verification Engine prevents accidental overwrites of critical parameters, and all actions are logged to the JLR Service Cloud for traceability.
