Follow the KTAG software diagram to identify the boot point and the GPT connection points. Solder Connections: Boot: Solder a wire to the designated boot pin on the PCB. CNF1: Solder a wire to the CNF1 point. GPT1 & GPT2: Solder the GPT cables to the required points.
— some clone cables have miswired CAN or K-line.
Before attempting to read the Mercedes EDC17CP57 with Ktag 7.020 GPT cable, make sure you have the following:
Plug the soldered wires into the corresponding slots on the KTAG breakout box. Connect the GPT cable to the designated port. 3. Understanding the Communication Process How to read Mercedes EDC17CP57 with Ktag 7.020 GPT cable
Connect your bench power supply to the Ktag tool and turn it on. Plug the Ktag 7.020 into your computer’s USB port. In KSuite, select .
Select . The software will typically provide a generic diagram, but the GPT cable wiring is specific. Step 2: Wiring & Pinout Connection

Mercedes EDC17CP57 Ktag 7.020 , you must use the "GPT" (Guided Password Transmission) function to decrypt the secret password of the Tricore microcontroller. This allows you to read and write both Flash and EEPROM memories. Essential Preparation (typically v2.23 or v2.70 for Ktag 7.020). : Ensure your Ktag 7.020 is connected to a stable power supply (approx. 13.5V). : Select the protocol for Bosch EDC17CP57 IROM TC1793 (often listed under Mercedes protocols or protocol #1033). Connection Pinout (Standard) You will need the cable for power/CAN and the GPT flat cable. Connector/Pin Number Wire Color +12V (Power) Pins 03, 15, 16 Red/Orange Ground (GND) See Diagram (F34NTA15) Specific GPT Pin See Diagram (F34NTA15) Specific GPT Pin Specific internal pad Step-by-Step Reading Process
The software will display specific wiring diagrams. Always cross-reference your exact board generation with the on-screen schematic before executing standard pins. Step 2: The Physical Wiring Layout (Pinout Guide)
It is highly recommended to consult with licensed automotive technicians or certified chiptuning specialists who have the necessary calibration tools and insurance. GPT1 & GPT2: Solder the GPT cables to the required points
, provided you have the patience for careful physical disassembly and soldering. ktag-7.020-mb-w166-edc17cp57-7 | OBDII365.com Official Blog
ESD (Electrostatic Discharge) wrist strap. Step 1: Locating and Opening the ECU
The GPT functions allow the Ktag hardware to intercept the security handshake signals, extracting the decryption keys necessary to unlock both the internal flash memory and the EEPROM sectors. : Connect to Pin 52 (typically the Yellow GPT wire). GPT 2 : Connect to Pin 53 (typically the Orange GPT wire). Step 3: Executing the Reading Process in K-Suite
