This could also be due to a drop in battery voltage, aftermarket components, connections, wiring issues, or a delay or interruption in the data transmission into the module.

E4399/M4403 is generally related to a communication loss between the module and the programming tool.It typically isn’t related to a module or vehicle issue. E4398 indicates a programming error due to a lack of, or incomplete, calibration data files.E4398, E4399, E4403, E4414, E4423, E4491 (E4423 and E4491 are the most common)Īll of these error codes have to do with some sort of programming failure:.Typically you’ll see one or more of these codes displayed on your computer screen:

In addition, you may find a communication error - code U0101 - stored in some of the other modules. You may see some transmission data, but the data parameters are coming from the ECM, not the TEHCM. The codes are displayed on your computer’s reprogramming screen as part of the failed programming process. These codes typically aren’t the codes you’ll see on your scan tool, because your scan tool won’t be able to communicate with the TEHCM. When you face one of these situations, you’ll likely have codes associated with the programming failure. The vehicles in the example scenarios aren’t global modules, but the lockout action operates as if it were a global controller platform. You can’t swap modules in the global platform vehicles because the module ID won’t match, which will lock the module out. You may already be aware that GM has Global A and Global B technology incorporated into many of their modules. Everything goes fine until they get an Error Message, Program Failed, and the transmission won’t work properly because it’s stuck in default mode. It appears to have a TEHCM problem, so the technicians replace it.

Scenario 3 - A vehicle comes in with an issue related to the transmission.

Once again, everything goes fine, right up until they get an Error Message, Program Failed, and now the new transmission won’t operate properly because the system’s in default mode.

The customer is price-sensitive, so they decide to install a reman or salvage yard unit. Scenario 2 - A vehicle comes in with an issue related to the transmission.So the manager now has to explain why a vehicle that drove into the shop now can’t drive out of the shop. In addition, the transmission is now in default or limp mode.

No matter what they do from this point, the software won’t load. Everything goes wonderfully right up to the end when they receive an Error Message, Program Failed, indicating the software didn’t load properly.

The technicians decide a software update may address the issue, so they start to install the update.

Scenario 1 - A vehicle comes in with an issue related to the transmission.

Here are a few common scenarios and how they play out: A year or so ago, these units seldom experienced problems, but today, as they become more popular and as reprogramming system changes have been implemented, difficulties are showing up.

In addition, many modules now require the program be stored in a flash drive - one with at least 4GB formatted to FAT32 - because theĪs of late, a number of technicians have run into problems loading software or calibrations into the TEHCM on the 6L and 6T series transmissions.

Eliminate or disconnect aftermarket equipment that could interfere with the programming process.

Select the correct RPO codes based on how the vehicle is equipped.

Make sure you have a good internet connection and PC-to-pass-thru connection, preferably hard-wired to your reprogramming equipment.

Make sure your scan tool, pass-thru device, and computer have the correct software.

Check the battery and replace it if needed prior to programming.

Never use a battery charger the voltage fluctuations can cause programming errors.

Use a “memory saver” to regulate and maintain battery voltage.

There are some basic processes to follow to minimize the chance of issues during programming. Some programming issues are “self-inflicted,” while others are due to vehicle issues or software conflicts. Like other vehicle technology, the reprogramming process continues to evolve, and with that evolution, problems with programming continue to occur. More and more problems are being addressed by software updates rather than hard part replacement by all manufacturers. Programming a vehicle is becoming part of everyday service for most shops today.
