CM554 QSC 8.3 ECM Reflash issue

[J99]

Hi all,

On a QSC 8.3 CAPS CM554 from 2003, I purchased a new ECM without Calibration, planning to do the calibration myself (as I was able to with Calterm 3.17 on the original one).

When trying to download the original cummins calibration, it throws an error "DCLDevice Write Failed. DCL Status = 27. The remote node could not validate the restricted access node."

When going into the Calterm 3 Unlock Menu, I can see that the ECM came in with Calibration Security "Secured" unlike the original one (and in RomBoot, normal, Module Status 5EED). Using the button "Switch" next to the Calibration Security, it is not doing anything.

Trying with Calterm 5.16 on another PC, when trying to reflash it tells me "Module is secure. Download to secured modules is not supported by Calterm".

Do you have any advice how I can manage to unlock this ECM and get my Calibration in ?

Thanks for your help !

In Calterm 3, select Tools from the top menu, then click Unlock. This will open the Calterm Unlock utility.

Click Datalink and verify that the communication settings are correct. Once verified, return to the Unlock window and click Find Devices. The tool should detect 0x00 (hex) / 0 (decimal), which is typically Engine #1.

Next, click Display Current Status. Under Calibration Security, the ECM should report Locked. If it does, click Switch. This sends a special command over the datalink that instructs the ECM to enter Unlock Mode.

After the ECM has been unlocked, try flashing the calibration again.

If the flash still fails, troubleshooting becomes more difficult. Older ECMs can be extremely finicky about which E2M file is used during the flash process. In that case, there is a good chance you are using the wrong E2M file for the ECM.

an FYI for next time...

Buy from a certified stealers%it, cummins directly.. YOU GET A BRAND NEW CIRCUIT BOARD INSIDE IT!. They can manufacture that board for far less moneys than it would be to hire some team of people to sit and solder on them + troubleshoot. - ALL they re-use in a reman ECM is the casing and frame inside it.. and slap a whole new board in them. That is why all of the the connectors (that are part of the board and not the casing) on the front if it is always brand spanking new as well.

AND YES... ALWAYS pay them extra to flash it fully. All ready to go for your truck so that you can just drive away. This is really cheap insurance against having to buy a second one if there is anything wrong with it out of the box. AS with any electronics, .. THEY WILL NOT TAKE IT BACK IF YOU CLAIM ITS DEAD OR HAVE ISSUES WITH IT NOT WORKING, ETC!.

It needs to be flashed by them (usually costs a couple hundred bucks extra) and then simply installed and then the engine run for 10+ minutes BEFORE doing anything else to it (like any custom programming, etc) if need be. This grantees that they cannot tell you that you caused it not to run.. and verifies that it is ok before you go fiddling with it.
