IMMOBILIZER EMULATOR FOR LAND ROVER DISCOVERY 3 / RANGE ROVER SPORT
Immobiliser emulator for LAND ROVER DISCOVERY 3 L319 / RANGE ROVER SPORT L320 / L322 vehicles.
Currently tested ECUs with which this emulator works include: SID204, SID203, DENSO MB279700-9240, 5WS40278B-T, 5WS40061F-T, 5WS40371C-T, 5WS40622B-T.
The immobiliser system library used in the ECU SID204 from LAND ROVER/RANGE ROVER vehicles is not the same as in JAGUAR with SID204, we have a different special emulator for Jaguar SID204.
We do not need to modify the flash file or the eeprom file in the ECU, so it remains in its original state, we only transfer the synchronisation bytes from the ECU to the emulator.
Please also read the general information on the difference between the immobilizer emulator and the so-called IMMO-OFF here.
Four wires should be connected: CAN-H, CAN-L, GND (ground) and +12 V IGN ( terminal „15”) or +12 V after the ECU/ECM relay. Ensure the connection adheres to the vehicle’s repair schematics.
The colors of the corresponding wires are specified in the photo.
The location of the eeprom 24C02 memory is also specified in the photo.
Please remember the CAN terminator – terminator resistor, is in many cases indispensable especially when the ECU works standalone.
On emulator PCB we have 3 x LED GREEN, RED, YELLOW, thanks to them we can carry out diagnostics of the emulator connection, they clearly indicate the current status of the CAN bus connection and the status of matching to the ECU.
The emulator is designed for the HS-CAN bus of LAND ROVER vehicles, replacing the communication of the immobiliser with the BCM based on the 9S12 + PIC18F6620 microcontroller, from which we are also able to extract the synchronisation code for the emulator.
This solution allows the 2.7 TDV6, 3.6 TDV8 Landrover engine to be used for buggy projects.
Before analysing the files, we will verify the ECU by reviewing the logs provided by the customer. The CAN-bus log can be captured on the bench (there are many damaged ECUs with incorrect CAN-bus communication). Therefore, a CAN-bus analyser or logger is mandatory.
In the process of preparing and testing the emulator, we need ECU files from all 3 areas: MPC, Flash and eeprom, as we create a copy of the ECU on our table and test the data for proper emulator operation.
Custom-made immo emulator edition for V8 petrol engine.

A special option for people swapping these engines for other vehicles, boat, buggies and other swaps, a simple way to unlock – immobilizer emulator.
WARNING: We receive a large number of inquiries with the content „HELP IMMO-OFF?” … We do not respond to such messages at all.
The service of preparing the emulator is intended for professional companies specializing in automotive electronics, the company submitting the inquiry must have a vehicle (e.g., a buggy or similar) in their workshop and significant experience in automotive electronics, the sender of the enquiry must provide detailed information on the problem he wishes to solve by means of our services.
If you are an EU-based automotive electronics company, you can send us an engine control unit for assembling and testing the emulator for service – please contact us or to one of My distributors .
In order to use this solution, the customer must be qualified as an automotive electronics technician and have the necessary diagnostic tools and wiring diagrams.
In the event of problems and the need for technical support, a CAN bus analyzer will be required in addition to the ECU files, as well as the ability to operate it.
