OBDSTAR DC706 Boot Mode Solution for GPEC2 ECM

 How to read and clone the GPEC2 module? This module is used in Jeep, Chrysler, Dodge, and other American CDI vehicles.

We will perform the process using the OBDStart DC706 ecu tool along with its MP001 adapter cable.

Step-by-Step Process:

Connection Setup
First, we connect to the vehicle via OBD. Then, we navigate through the tool’s menu to find the GPEC2 module. This module is used across multiple brands: Chrysler, Dodge, and Jeep. In our case, we are working on a Jeep with a PC56 / 66 Plus 95 320 system.

Adapter Configuration
Depending on your setup, you may use:

• A PC adapter with two wires (CAN High and CAN Low).
• An adapter with a GPTAN connector.

In all cases, you can read modules such as BDL03 Plus or BDL03, but you must add a 120-ohm resistor between CAN High and CAN Low for proper communication.
Alternatively, you can use BDL01, which already has the resistor built in.

Starting the Process
We begin by selecting the correct connection type in the tool menu.

Adapter MP001

It’s important to note: this programmer works online, unlike some others that work offline. Once connected, the device will initialize and prompt you to proceed.

Reading the Module
You have the option to read:

• External PROM
• Internal Flash

We proceed with reading the internal flash. The tool works quickly and accurately — truly impressive.

Saving the Data
After reading, we save the data to a file. The tool will ask you to save the dump — we do so, of course.

Switching for Cloning
Next, we switch the connection to another module (the donor) for cloning.
We change the wiring accordingly and prepare to write the data to the new module.

Important Notes:

Ensure correct resistor placement if needed.

Always save your reads before writing.

Use proper adapters and follow on-screen prompts carefully.

OBDSTAR DC706 ecu programmer is powerful and efficient, making complex procedures like GPEC2 cloning much more accessible.
