5.1 Special function "Transponder Tool"
Required equipment
- Abrites AVDI interface
- The transponder programmer, connected to the AVDI interface
- For cloning: a TPX1 or an empty (brand new) TPX2 transponder, produced by JMA Company or compatible
- For preparation of a key by dump: an IC programmer
Before you start
Before usage of special function "Transponder Tool" please be sure that your transponder programmer is connected to the AVDI interface.
When your transponder programmer is detected a list of sub functions will appear:
- Identification of a key or transponder
- Cloning of a key/transponder
- Preparation (production) of transponders ready for usage with Daihatsu vehicles
- Programming transponder by the dump of immobilizer/smart system
Before usage of your programmer please take into account:
- while operating, the antenna of the transponder programmer should be kept away from metal surfaces;
- the key or transponder should be placed near the antenna to allow proper reading and programming.
Key and transponder positions
Transponder position should be at 1 cm from the antenna surface. Find below examples of some key and transponder positions:
Regular key example:
Smart key example:
5.1.1 Identification of a key or transponder
If you have a key or transponder simply place it near the antenna of the programmer and press the "Read/Identify" button. A message about the type of your transponder and the content programmed will be displayed. If your transponder is one of the known transponder types, information about this type (e.g. Texas Crypto 4D) will be displayed.
Abrites Diagnostics for Daihatsu will try to recognize ONLY transponders/keys used in Daihatsu vehicles. These types are as follows:
| Type | Description |
|---|---|
| Fixed transponder Texas 4C | This type of transponder consists of only an identification number and does not contain any authentication logic. |
| Crypto transponder Texas 4D | This type of transponder consists of a set of data fields programmable by the user that can be used by the immobilizer system to decide whether the key has been programmed in the vehicle. In addition this transponder provides the ability for programming of 40 bits secret keys which can be used by immobilizers to identify the transponder by a special authentication algorithm. |
5.1.2 Cloning of a key or transponder
With the help of this option you can prepare a fully functional cloning of an existing vehicle's keys. Supported keys/transponders for cloning are:
| Original | In the cloned key use |
|---|---|
| Texas 4C fixed | Transponder type TPX1 produced by JMA Company or compatible |
| Texas 4D | An empty (brand new) transponder named TPX2 produced by JMA Company or compatible |
5.1.3 Preparation of transponders/keys ready for usage with the vehicle
Usually when you need to add an additional key to the vehicle or all keys are lost you need to use some kind of key or transponder. The transponder inside of the key should be with a special content in order for future programming by diagnostics to be possible.
The "Production" utility provides the ability to program an empty (brand new) transponder as a transponder ready for acceptance by the immobilizer system of the vehicle. Transponders applicable for this utility are virgin Texas 4D transponders or TPX2 transponders.
5.1.4 Preparation of a key by dump of immobilizer
This utility will provide the ability to prepare a key when you have the dump of the immobilizer system.
1. Read the EEPROM
Read with an IC programmer the EEPROM of your immobilizer/smart module.
2. Load the dump in the application
Load it in the application - it will automatically identify the type of your vehicle and the needed transponder or key for programming.
3. Program the key and the new dump
When the key is programmed, with the same IC programmer you can program the new dump (modified by the application) back in the immobilizer/smart module.
