This document describes a probe designed for programming VAG MED17.5.2 Bosch ECUs, specifically for use with an AVDI (Abrites Vehicle Diagnostic Interface) flash tool. The probe is designed to simplify the process of reading and programming these ECUs by eliminating the need for soldering.

Function Description:

The primary function of this probe is to provide a non-invasive interface for programming VAG MED17.5.2 Bosch ECUs. It facilitates communication between the ECU and a flash tool (such as AVDI) for operations like reading passwords and programming the ECU in boot mode. The probe is equipped with LEDs to assist in accurate alignment with the ECU's BDM (Background Debug Mode) points. It also integrates switches for controlling "Boot" resistors and the ignition feed, which are crucial for different programming stages.

Important Technical Specifications:

Compatibility: Specifically designed for VAG MED17.5.2 Bosch ECUs.
Flash Tool Integration: Connects to flash tools via an OBD cable, with a serial port connection on the probe itself.
Power Supply: Requires an external power supply connected via a power jack (C).
Alignment Aids: Features integrated LEDs for precise alignment with the ECU's BDM points.
Boot Resistors: Includes DIP switches (D) to enable or disable "Boot" resistors, which are essential for specific programming modes (e.g., reading passwords).
Ignition Control: Features an ignition selection switch (E) with "ON," "OFF," and "K-Line" positions.
K-Line Connection: For the AVDI version of this probe, the ignition selection switch (E) must always be set to the "K-Line" position. This is because the AVDI requires a permanent connection via a 510 Ohm resistor between the K-Line and 12V, rendering the "ON" and "OFF" positions of this switch non-functional in this specific configuration.
BDM Frame Integration: Designed to fit into most standard BDM positioning frames, allowing for secure and stable contact with the ECU.

Usage Features:

The probe offers several features to streamline the ECU programming process:

Solder-Free Operation: A significant advantage of this probe is that it eliminates the need for soldering, which reduces the risk of damage to the ECU and simplifies the connection process.
Accurate Alignment: The integrated LEDs provide visual guidance for aligning the probe's pins with the corresponding pads on the ECU, ensuring proper contact.
Switchable Boot Resistors: The DIP switches (D) allow users to easily enable or disable the "Boot" resistors. This is critical for different programming phases, such as reading the password (where they are lifted up) and programming in boot mode (where they are pushed down).
Ignition Control: The ignition selection switch (E) allows for control over the ignition feed. However, for the AVDI version, it must remain in the "K-Line" position at all times due to the AVDI's specific K-Line requirements.
Modular Connections: The probe uses standard connections: a serial port (A) for communication with the probe itself, a power jack (C) for the power supply, and an output (F) that connects to the OBD cable of the flash tool.

Operational Workflow:

Preparation:
- Ensure the power switch (B) is in the "OFF" position before placing the probe. This is a critical safety measure to prevent damage to the ECU from live pins during alignment.
- Place the probe into a BDM frame and secure it.
- Connect the adapter cable (G) from the probe's serial port (A) to the flash tool's OBD cable (F).
- Connect the power supply to the probe's power jack (C). The LEDs will illuminate to assist with alignment, but the ECU will not be powered until the power switch (B) is turned on.
- Carefully adjust the ECU within the frame and move the probe retainer to ensure all pins make proper contact with their designated positions on the ECU. The retainer should move smoothly without backlash.
- Refer to the diagram on page 3 of the manual, which highlights the specific pads on the ECU (marked in red) that must make contact with the probe.
Reading Password (for TP8+ only):
- Lift up the Boot DIP switches (D).
- Set the Ignition switch (E) to the "ON" position.
- You can now proceed to read the password.
Programming the ECU:
- Push the DIP switches (D) down.
- Set the Ignition switch (E) to the "K-Line" position.
- You can now proceed with programming the ECU over boot mode.
Disconnecting:
- To safely disconnect the probe, first, TURN OFF THE POWER Switch (B).
- Once the power supply is disconnected, it is safe to lift the frame and probe away from the ECU.

Maintenance Features:

Robust Design: The probe is designed to fit into standard BDM frames, suggesting a robust and stable connection during operation.
No Soldering Required: The elimination of soldering reduces the need for specialized tools and skills for connection, minimizing potential maintenance issues related to poor solder joints.
Clear Instructions: The manual provides clear, step-by-step instructions for handling, adjustment, and operation, which helps prevent misuse and potential damage to the device or ECU.
Safety Precautions: Emphasizing the importance of keeping the power switch off during alignment is a key safety feature that protects both the probe and the ECU from electrical damage.
