Vehicle diagnostic devices are essential for the maintenance and repair of all types of vehicles, be it cars , trucks or motorcycles . These devices enable the reading and deletion of error codes generated by the vehicle's control units using the error readers. With a high-quality vehicle diagnostic device, workshops and private users can quickly and precisely identify and resolve the cause of problems. Thanks to the comprehensive diagnostic options and the ability to program control units , professional diagnostic devices are indispensable tools for every workshop. Regular use of these devices extends the service life of the vehicle and increases operational reliability.
Professional diagnostic devices offer far more functions than simple OBD readers. They not only allow you to read and delete error codes with the error readers , but also to carry out live data tests and actuator tests. They also offer advanced functions such as calibrating control units and adjusting comfort functions. In today's world, where vehicles are becoming increasingly complex, such comprehensive diagnostic options are invaluable. With a professional diagnostic device, workshops can ensure that they are able to carry out even the most demanding repairs and maintenance work efficiently and precisely.
OBD diagnostic devices are standardized tools used in almost every modern vehicle. They allow you to read engine and emissions data and monitor various vehicle systems. With an OBD diagnostic device, potential problems can be identified early and resolved before they lead to major damage. These devices are of great use not only to workshops but also to vehicle owners. They offer an easy way to monitor the condition of the vehicle and carry out necessary maintenance work in a timely manner. Car diagnostics become more efficient and effective with OBD diagnostic devices.
Car diagnostics play a crucial role in the long-term health and performance of a vehicle. By using modern diagnostic devices, mechanics and vehicle owners can make precise diagnoses and carry out targeted repairs. This saves time and money and helps extend the life of the vehicle. Modern car diagnostics not only include reading error codes with the error readers , but also analyzing live data, carrying out special tests and adjusting control units. With a reliable diagnostic device, you always have all the important information at hand to optimally maintain and repair your vehicle.
Anyone working in vehicle diagnostics with General Motors vehicles knows the GM Tech 2 diagnostic tool as one of the most reliable tools for reading fault codes, programming ECUs, and monitoring systems. However, without the right cables and adapters, the device is useless. That's where our product range comes in: At auto-diagnostik.de, you'll find exclusively accessories and adapter plugs for the GM Tech 2 system – ideal for workshops, automotive technicians, and ambitious DIY mechanics.
Whether main cable, CANDI module or 16-pin adapter plug – our products guarantee secure communication between vehicle and diagnostic device and enable you to perform stable, precise and fast diagnostics.
The GM Tech 2 diagnostic tool was originally developed by General Motors to perform professional diagnostics on vehicles from the GM group. This includes, among others, Chevrolet, Buick, Cadillac, GMC, and European brands such as Opel and Saab.
However, the device alone is not enough: Special accessories are required for it to be operational. These consist of:
a main cable that connects the device to the vehicle,
a CANDI module that supports CAN bus vehicles,
as well as a 16-pin adapter plug that allows connection to the OBD2 interface.
All these elements are crucial for the GM Tech 2 to function at its full potential – and you can find exactly these accessories in our shop.
A good adapter plug is the heart of reliable diagnostics. It ensures an uninterrupted connection between the diagnostic tool and the vehicle's OBD2 interface. With the appropriate GM Tech 2 adapter plug, you can:
Read and clear fault codes from all relevant control units,
Read live data, e.g. sensor values, motor data and system voltages,
Perform coding and programming on control units,
Resetting service intervals or performing functions such as key learning (depending on vehicle model and software version).
Our adapter plugs are specifically designed for GM vehicles, thus offering the highest compatibility and diagnostic quality.
Modern vehicles manufactured from approximately 2004 onwards are generally equipped with a CAN bus system. To diagnose these vehicles with the GM Tech 2, the CANDI module (Controller Area Network Diagnostic Interface) is required. It acts as an intermediary between the diagnostic tool and the vehicle's CAN network.
Key advantages:
Supports the diagnosis of new GM vehicles with CAN protocol,
Enables access to control units that could not be addressed without a CANDI module,
Robust construction for continuous use in workshops,
Compatible with the GM Tech 2 via the standardized interface.
A CANDI module is therefore essential if you want to diagnose not only older vehicles (e.g. Opel Astra G, Vectra B), but also newer models such as Chevrolet Cruze, GMC Acadia or Cadillac CTS.
The GM Tech 2 main cable, part number P28769, is one of the most commonly used connection cables for diagnostics on GM vehicles. It connects the Tech 2 device directly to the vehicle's diagnostic connector.
Features:
Robust rubber coating and plug contacts for high durability,
Specifically designed for professional use,
Compatible with the CANDI module and the 16-pin OBD2 adapter,
Flexible cable design, ideal for mobile applications.
Especially in workshops that regularly service GM vehicles, a reliable and durable main cable is essential. At auto-diagnostik.de, we offer tested quality – for a secure connection, every day.
The 16-pin adapter plug bridges the gap between the GM Tech 2 diagnostic tool (via the main cable) and the vehicle's OBD2 interface. This adapter ensures that your Tech 2 is also compatible with vehicles that already have the standardized OBD2 port.
Advantages:
Perfectly fitting connection without wobbly transitions,
Fast and error-free reading of control units,
Broad vehicle compatibility within the GM group,
High-quality materials for a long service life.
The precise processing ensures a clean, interference-free data flow – and thus a clear error analysis and professional evaluation of all vehicle systems.
