Save the files to a secure directory. Do not alter the file extensions generated by KSuite. Critical Troubleshooting Tips
: Typically version 2.23 or 2.25, installed on a stable Windows machine.
Choose the specific plugin for the EDC17CP57. For Ktag 7.020, this is typically (or P693 ), labeled as Mercedes Bosch EDC17CP57 . Step 2: Main Connector Pinout Configuration
Select . The software will typically provide a generic diagram, but the GPT cable wiring is specific. Step 2: Wiring & Pinout Connection How to read Mercedes EDC17CP57 with Ktag 7.020 GPT cable
: Ensure you are using a compatible hardware version (often referred to as the "red PCB" version). GPT Cable : Typically designated as cable 14P600KT06 Go to product viewer dialog for this item. .
Connect the Red wires to Pin 1 and Pin 5 . Ground (GND): Connect the Black wire to Pin 2 . CAN High (CAN-H): Connect the White wire to Pin 68 . CAN Low (CAN-L): Connect the Blue wire to Pin 67 . Step 3: GPT Cable Connections
Locate the small square pads on the PCB labeled CNF1 , CNF2 , and CNF3 . These are usually located near the main processor. Save the files to a secure directory
Connect the from the Ktag harness directly to the specific single pad on the circuit board as illustrated in the K-Suite help guide. Use a positioning frame with a spring-loaded probe pointer or solder a micro-wire directly to the pad. Step 4: Reading the ECU Data
: Select the Tricore GPT protocol. This is often listed under Protocol 700 for this specific ECU.
: The standard multi-colored ribbon cable ( 14P600KT02 ). Choose the specific plugin for the EDC17CP57
: Plugin 697 or 704 (varies depending on specific Mercedes-Benz K-Suite platform listings). Required Equipment Checklist
– you must open the ECU.
The Bosch EDC17CP57 relies on an Infineon Tricore TC1793 processor. Older tuning tools required physical soldering to boot pads on the motherboard to bypass anti-tuning protection (TPROT). Ktag 7.020 simplifies this via its GPT communication protocol.
