GPT 1: Connect to the specific pad designated in the KSuite help manual. GPT 2: Connect to the secondary designated pad.
Ktag will first perform an "Identification" to check the hardware and software numbers.
Ensure the GPT 1 and GPT 2 wires are not swapped. These are polarity sensitive. How to read Mercedes EDC17CP57 with Ktag 7.020 GPT cable
It will then attempt to "Check for Password." This is where the GPT cable does its work.
Save the files individually or as a compressed backup when prompted. Troubleshooting Common Issues GPT 1: Connect to the specific pad designated
To perform this operation successfully, you will need the following tools: Ktag 7.020 Master or Slave unit. GPT Cable (supplied with Ktag 2.23/2.25/2.47 kits). 14P600KT02 cable for power and CAN lines. A stable 12V-14V power supply (minimum 2A).
The software will identify the correct Protocol: P682 (or similar depending on the specific hardware variant). Wiring and Connection Steps Ensure the GPT 1 and GPT 2 wires are not swapped
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 GPT signals allow the Ktag to communicate with the processor's security layer to unlock the "No Help" password.
