How To Read Mercedes Edc17cp57 With Ktag 7.020 Gpt Cable May 2026
By following this guide, you can safely extract the original file for EGR/DPF deletes, AdBlue removal, or performance remapping. Always keep your original backup file in a safe place before writing any modified data back to the ECU.
To put the ECU into "Boot Mode," you must connect a grey wire (Boot) to the specific boot pin on the PCB. In many Mercedes EDC17CP57 variants, this involves a single soldering point or a probe held firmly against a small resistor or pad on the underside or topside of the board. The Reading Process Once the hardware is connected and the ECU is powered up: Click "Select" on the protocol in KSuite. Go to the "Read" tab.
Soldering iron and fine wire (if using a boot pin connection). Positioning frame with probes (recommended for stability). Software Configuration How to read Mercedes EDC17CP57 with Ktag 7.020 GPT cable
Open your KSuite software (version 2.23 or higher is recommended for Ktag 7.020). Select "Car" from the main menu. Choose "Mercedes" as the manufacturer. Locate the model of your vehicle. Select the ECU: BOSCH EDC17CP57.
To help you get the connections right, would you like the specific for your Mercedes model or the resistor values often used for boot mode? By following this guide, you can safely extract
Ensure you are using KSuite 2.23 or 2.25. Versions older than 7.020 firmware often lack the GPT algorithms for newer EDC17 units.
The EDC17CP57 requires a specific combination of power, ground, CAN signals, and GPT signals. Follow the Ktag on-screen connection diagram strictly, as pinouts can vary slightly by hardware generation. Main Connector Pinout Pin 5, 46: +12V (Red) Pin 2: GND (Black) Pin 68: CAN-L (Blue) Pin 67: CAN-H (White) GPT Connection In many Mercedes EDC17CP57 variants, this involves a
It will then attempt to "Check for Password." This is where the GPT cable does its work.
Ktag will first perform an "Identification" to check the hardware and software numbers.
The software will identify the correct Protocol: P682 (or similar depending on the specific hardware variant). Wiring and Connection Steps
