Remote Engine Start (RES) enable for Jaguar & Land Rover — let the engine be started remotely (from the key or app) to pre-heat or pre-cool the cabin, and set how it behaves. Set via the CCF and coded to your VIN / As-Built over OBD, remote & mobile.

What this activation does

  • Enables Remote Engine Start so you can start the engine from the key fob or app to warm up or cool down the cabin before you get in.
  • Set how it behaves — whether the engine stays running in Park/Neutral and when it switches off (e.g. when lamps are used).
  • Software enable via the CCF, coded to your VIN / As-Built. Availability depends on model/market and hardware.

Choose the option that matches your vehicle

Dropdown option What it means
Not supported The vehicle does not support RES — factory place-holder, do not select.
Vehicle supports RES Enables Remote Engine Start.
RES not supported Marks RES as unsupported — the feature stays off.
Stay ON in park or neutral After a remote start the engine keeps running in Park or Neutral.
Switch OFF in park or neutral The engine switches off when Park or Neutral is selected.
Switch off with position lamps or greater The remote-started engine stops once position lamps (or more) are switched on.
Switch off with dip beam lamps or greater The remote-started engine stops once dipped-beam headlamps (or more) are switched on.
Error Factory place-holder value — not a real choice, do not select.

Key terms explained

  • Remote Engine Start (RES): Starting the engine remotely (key fob or phone app) so the climate system can warm or cool the cabin before you drive.
  • CCF (Car Configuration File): The master list of feature flags stored in the vehicle. Setting a value here switches a factory feature on or off. All of these activations are done by editing the CCF, not by fitting parts.
  • As-Built: Your vehicle's original factory configuration record, tied to the VIN. Every change is written back against your As-Built so the car stays consistent with JLR records.
  • Coded to your VIN: The change is applied to your specific vehicle over the OBD diagnostic port — remote and mobile, no bench work and no new hardware.
  • Error / Undefined: Factory enumeration place-holders that exist inside the parameter list. They are not real choices — do not select them. Pick the plain-English option that matches your vehicle.

The CCF parameters behind Remote Engine Start

The dropdown above maps to these values in the Car Configuration File:

CCF address Parameter Block Byte Bits Values (from the CCF data set)
0x4421 Remote Start Capable 0x44 2 1–0 01 = supports remote engine start, 02 = remote start not supported.
0x4427 DRL Transmission Interaction 0x44 2 7–5 01 = daytime running lamps stay on in park / neutral, 02 = daytime running lamps switch off in park / neutral.
0x4424 DRL Main Lighting Interaction 0x44 2 4–2 01 = switch off with position lamps and above, 02 = switch off with dip beam and above.

Remote Engine Start lets the engine be started from the key fob or the phone app to warm or cool the cabin before you get in. It needs a car whose body and engine modules support remote start. Where the support is present but the flag was never enabled we switch it on; software cannot add the capability to a car that does not have it — we check your As-Built first.

Remote Engine Start on Jaguar Land Rover — 2013 to 2026

Earliest model year the options existed on each line:

Model Platform Model years Notes
Range Rover / Range Rover Sport L405 / L494 2013–2022 Remote engine start where the body and engine modules support it.
Land Rover Discovery / Defender L462 / L663 2017–2026 Remote engine start on the current Land Rover lines.
Range Rover / Range Rover Sport L460 / L461 2022–2026 Remote engine start on the current platforms.

Earliest model year remote start existed on each line; it needs a car that supports it. We confirm by VIN.

Two ways we switch this on — both remote, no parts

Depending on model year and architecture, Remote Engine Start is enabled by one of two methods. We pick the correct one for your VIN — you do not need to know which in advance.

  • CCF editing over OBD — on cars that support remote start we set the remote-start values above in the Car Configuration File, write them back against your As-Built, then re-configure the body and engine modules so remote engine start works from the fob and the app.
  • OEM-tool online configuration — where the module holding the flag needs its configuration re-issued from the manufacturer’s programming database rather than a direct CCF value, the same result is completed remotely through the OEM diagnostic tool’s online configuration for that module.

Either route is performed over the OBD diagnostic port, remote and mobile, with no bench work and no parts. The change is reversible the same way.
