OBDSTAR DC706 Clone GM ACDelco E39A ECM Step by Step

 Tutorial: how to clone GM ACDelco E39A ECM step-by-step using OBDSTAR DC706 on bench.

Model example: 2014 GMC Arcadia

Purpose: engine hard start, there were ECM code saying that lost communication with the ECM.  Need to replace ECM module (with an used one)

 

Procedure:

We’re going to go ahead with the cloning process.

Quick search E39A ECM type

Check wiring diagram. As you can see right here two Powers, ground can high, can low.

Get the module connected with dc706 and jumper cables. Put on Wi-Fi.

We’re going to do on bench mode. Turn on ignition on P004 adapter.

Press ECU Info, it should communicate and give us the VIN number and everything of the vehicle ECU.

We’re going to go ahead and back up the eeprom and the Flash.

You’ve got to connect first before you can actually read and modify the eeprom and the Flash.

Read the shadow flash password and save.

Read internal eeprom and save. Read eeprom very fast.

Read internal flash and save. It takes about 3 minutes.

Then read pin code and as you can see there’s the PIN code for this vehicle is 1833.

We’re now going to connect up the donor ECM with obdstar dc706 and write this information into the donor ECM and then connect it to the vehicle.

Go ahead and connect it up and then we’re going to copy the data over to it.

We got everything hooked up and gave power to the ECM.

Read ECU infor, that’s the VIN for the donor ECM. Back this up.

Backed it up as in this step is not necessary but just did it anyway.

We’re going to write the original flash to the donor ECM. Load External file.

It’s already in our default folder and it’s called it should be this one internal flash.

It’s going to first erase the flash on the donor unit before it writes the file to it.

It’s successfully written the Flash so now we’re going to write the eeprom.

Load it from external file and it is already in our default folder.

Write the eeprom should be pretty quick. It is written.

Read the PIN code which should reflect the first one 1833.

So now we’re going to do disconnect.

Read ECU info of the donor ECM again. It should reflect our VIN number from the vehicle and not the donor ECM.

Then connect ECM to the vehicle. It should be Plug and play now.

Remove the original and plug in our donor that we just cloned and see if there’s any change this vehicle.

If there is an extended crank, clear fault code because some PCM error messages were occured.

There is no security light and it should be a crank and possibly no start because there’s most likely an engine issue here so checking light came on right away.

Security light should go off and it did so that is a successful clone.

Done.
