|Values, configuration settings, and other stored information which can be read from the ECU, edited and then rewritten back. Read settings can also be stored as a standard HTML page for reference. These pages can then later be re loaded and re written back to the ECU. Please note that some values may be read only due to the fact that they are supplied from the ECUís ROM or are internally calculated.
- GM code: The GM code is a component of a vehicle configuration coding scheme which is a method from which the vehicle manufacturer can identify any specific vehicle variant using this in combination with SA code and VN code.
- SA code: The SA code is a component of a vehicle configuration coding scheme which is a method from which the vehicle manufacturer can identify any specific vehicle variant using this in combination with GM code and VN code.
- First 4 digits of VN number: It is interesting to note that the EWS 3D Immobiliser only stores the first four digits of the VN number. It does not store the remaining 6 digits of the code.
- Information field 1: Field in the ECU memory that is used to store data. For L322 and Freelander, this first 8 characters are the AGM code, the next 16 characters are the ASA code. For Rover 75, the first 10 characters are the last 10 characters of ASA code, the next 4 characters are the last 4 characters of AVN code (it will contain 32 times hexadecimal characters)
- Information field 2: Field in the ECU memory that is used to store data. For L322 and Freelander, this first 10 characters are the AVN code. For Rover 75, this field is empty (will contain 32 times "F").
AGM Code/ASA Code/AVN Code: The AGM Code, the ASA Code and the AVN Code are used to identify the personalised configuration of the vehicle - which options have been set or not by Land Rover. In addition, under the "Other Systems" page there is a function which allows the GM, SA and VN Codes to be disassembled from the code into their relative meanings and vice versa, a code to be made from the vehicle configuration. This function in the other settings also covers the AGM, the ASA and the AVN to convert them from code to meaning and from meaning to code.
These codes are used by Land Rover's Testbook to configures the map to talk to any ECU on the vehicle. It uses the GM, SA and VN codes in order to tell it what options the vehicle has, what specification it has, in order to correctly code all the other ECUs in the vehicle. Similarly, the AGM, ASA and AVN codes are used to configure the personalised settings that the customer may have had put on to their vehicle at other dealerships, so that if the codes are incorrect, this may mean that any work done to it at a Land Rover dealer may end up with the vehicle being incorrectly programmed.
- Gearbox type: This tells the EWS 3D Immobiliser whether to look for the gearbox to be in PARK or NEUTRAL or not, for inhibiting starting as the gear interlock. This is preset from the factory and cannot be changed.
- EMS Message Type: This changes the coded mobilisation message which is being sent to the engine management in order to start the engine from being the EWS 3 type which is on later vehicles including the Range Rover or earlier systems using the EWS 2 configuration of message. This is preset from the factory and cannot be changed.
- K-bus Configuration: This denotes if K-bus messages are sent or not. Options are ENABLED or DISABLED and for the Range Rover the choice is normally DISABLED. This is preset from the factory and cannot be changed.
- Starter Cutoff Speed Value: For EWS 3D ECUs with a coding index of 81, this is the engine speed at which the starter will cut out. The value shown is the engine RPM divided by 100. The values set are as follows:
For EWS 3D ECUs with a coding index of 82, this is the engine speed at which the starter will cut out. The value shown is the pulses and it is the amount of pulses per 300ms. The values set are as follows:
| ||Petrol 4 cylinder||10|
| ||Diesel 4 cylinder||14|
| ||Diesel 4 cylinder M47 engine||11|
| ||Petrol 6 cylinder||10|
| ||Diesel 6 cylinder||14|
| ||Diesel 6 cylinder M57 engine||11|
| ||Petrol 8 cylinder (NGRR)||10|
| ||Diesel 8 cylinder||11|
| ||Petrol 12 cylinder||10|
| ||MEMS 4 cylinder||9|
| ||Diesel BMW engine||9|
| ||V6 petrol engine||12|
- Starter Cutoff Time Value: On the coding index 81 - this is the starter cut off time in 2 second increments. On the coding index of 82 this is the starter cut off time in 300 millisecond increments.
- Passive Immobilisation Time: This is the period of time after the key is removed before the immobiliser will automatically activate.
- EMS Message Timing Configuration: This is a value that determines the message interval spacing for the immobilisation message sent to the engine management ECU. It is 10 for all engines except for the KV6 which is the V6 petrol engine management which is 15.
- Part number: This is the manufacturer's identification part number for this ECU.
- Hardware number: This is the processor and circuit board version for the EWS 3D immobiliser ECU.
- Software number: This is the software within the processor of the EWS 3D immobiliser ECU.
- Supplier number: This is the unique number which can identify the individual suppliers.
- Bus index: This denotes the communication types available from this ECU to interface with data buses within the vehicle.
- Coding index: This defines the programming mask and type for this EWS 3D immobiliser ECU.
- Diagnostic index: This denotes the diagnostic communication protocols available with this ECU.
- Week of manufacture: This is the week number this ECU was manufactured.
- Year of manufacture: This is the year this ECU was manufactured.
- Currently inserted key: This is the key which is currently in the ignition.
Inserted key identity starts from 1 and ends at 10, but the keys are recognised in the ECU as being programmed into key slots 0 to 9.
- Key Slot Status 0-9: Key memory slots 0 to 9 shows if the key slot has been used or not. i.e. a key has been activated to this slot.
- Key Slot Enable 0-9: Shows if the key that has been activated to this slot is enabled or disabled.
- Random Code Tolerance Count 0-9: This is the number of errors that will be accepted from this key to allow it still to work. This is automatically incremented by the ECU if it detects intermittent or bad communications.
