JLR DTC Fault Code Lookup

How This Free JLR DTC Fault Code Lookup Works

This free JLR DTC fault code lookup searches the complete factory database of 10,991 diagnostic trouble codes compiled from JLR workshop documentation. Type an exact code with its suffix (P0087-00), a base code (P0087) to see every variant, a prefix (U2) to list a code family, or a plain keyword such as "fuel rail" — results appear instantly, capped at 20 per search. Each result shows the code, its workshop-manual definition and the control modules and systems it belongs to.

What a DTC Actually Tells You

A diagnostic trouble code is a standardised message a control module stores when it detects a fault — see the OBD-II trouble code reference for the underlying standard. The first letter names the system: P codes cover the powertrain (engine, gearbox, emissions), B codes the body (airbags, seats, locks, climate), C codes the chassis (ABS, suspension, steering) and U codes the network (module communication). The digits that follow identify the specific circuit or failure mode, and the two-character suffix (e.g. -00, -23) pinpoints the exact fault type — "signal stuck", "circuit open", "implausible signal" and so on.

Reading for JLR Codes Correctly

JLR vehicles use the standard OBD-II code structure, but the workshop-level meaning is model-specific — the same code can have different guided diagnostics on a Defender than on an XF. That is why each result here shows the definition together with the control modules that document it:

• Exact codes (P0087-00) return the single matching record
• Base codes (P0087) return every -xx variant of that fault
• Prefixes (U2) list the whole code family, 20 at a time
• Keywords (battery, camshaft, CAN bus) search definitions across the full 10,991-code database

When You Need SDD or Pathfinder Instead

A lookup tells you what a code means — it cannot read or clear codes on the vehicle. For that you need the right diagnostic platform: JLR SDD for pre-2017 CAN vehicles, or JLR Pathfinder and TOPIx Cloud for 2017+ DoIP vehicles. Not sure which generation yours is? Decode your VIN with our free VIN decoder first — the model year digit settles it. If you would rather hand the whole job to a technician, our remote coding service covers diagnostics, programming and retrofits in one session.

Beyond Definitions: Fixing the Fault on the Vehicle

Once you know what the code means, the next step is reading and clearing it on the car — the product strip above the search results lists the exact tools for the job:

• Complete technical data — TOPIx Cloud online access with factory guided diagnostics, wiring diagrams and programming authentication
• Engineering software — JET Master and JET Pro for coding and flashing, CCF Tools for configuration editing
• Diagnostic hardware — the SX-DOIP interface and JLR Enet adapters that read and clear these codes on the vehicle
• Retrofit kits & parts — genuine retrofit kits and activation packages for feature faults that are really missing-configuration codes
• Remote sessions — a technician diagnoses and clears the faults for you, per VIN, wherever the vehicle is
