Summary
This Preliminary information communicates a diagnostic tip on how to resolve a issue if the serial data authentication configuration did not complete correctly.
Condition
Some technicians may experience one or more of the following concerns after replacing or reprogramming a module on one of the new Vehicle Intelligence
Platforms. or VIP Vehicles
- DTC: U1962 set current in ANY Module
- No Start
- Invalid Data codes with certain modules even through you can still review the data with GDS2
- Unable to perform a theft relearn or learn remotes back to the vehicle
- Unable to perform Module setup or learn
You may also notice that the VIN number will not self-populate in GDS2
Cause
The serial Data Authentication Configuration procedure runs automatically as part of the programming procedure.
The Serial Data Authentication Configuration is a security handshake between all the modules on the vehicle. One of the main indicators the Serial Data Authentication Configuration did not complete properly is DTC: U1962 is current in one or more modules.
Correction:
The dealer will need to perform the Serial Data Authentication Configuration (SDAC) following Instructions in SI using Document ID: 5404959. Be sure the vehicle is Power Moded to the OFF position before running the Serial Data Authentication Configuration procedure.
If a vehicle will not complete the Serial Data Authentication Configuration (SDAC) after updating or replacing a module, please perform the following:
1. If a module was replaced, make sure the new module was SPS programmed correctly or the SDAC will fail and not complete correctly.
2. If a module such as the BCM is replaced, and the immobilizer learn needs to be completed after replacement, the tech needs to make sure that the SDAC completes correctly, or a pop-up message like the one below will be displayed:
3. If a vehicle will not complete the SDAC, run the SDAC (using the Serial Data Authentication selection in Techline Connect) again. Select the box in SPS controller list in the lower right-hand corner labeled “Serial Data Authentication Configuration”.
4. The SDAC will run 3 times before it fails. When it fails, there should be a pop box that shows up on the screen like the one below. Check and record the items listed under System and ECU. If the system box reads “Server” then the issue is related to the SPS system server or internet connection and not related to the vehicle. Attempt the SDAC again at a later time.
5. If the system box reads “ECU”, then the Global ID of the module that is causing the concern should be able to be obtained. In the example below, the Global ID is listed as K36, which is for the SDM. The module’s name can be found by looking at the global codes listed under “Control Module References” document in SI for the vehicle that is being working on.
6. Sometimes the pop-up box will read “ECU” but it will not give you a Module ID in the ECU box. In this case, the servicing dealer will have to contact Techline support and they will have to assist by getting a SPS log file from the dealership’s system. If this is the case, they must be contacted right after the SDAC failure. If any other programming is attempted before contacting Techline, then the SPS log will be erased.
7. Once the module that caused the concern has been identified, pull the fuse that supplies battery power to that module. Sometimes the fuse is a three-prong fuse that feeds other modules. In this case, the servicing technician will need to find a two-prong fuse to power the other module that was not involved in the SDAC failure.
8. If the SDAC completes after removing battery power from the module in question, that module will need to be replaced. Afterwards, verify that the SDAC completes after SPS programming of the new module.

Reprogramming
GM Diagnostic/Programming (TIS2Web)
Approved J2534 Device with TIS2WEB can reprogram 1996 and later All GM Modules.
To obtain the latest electronic controller calibration information for your vehicle, go to https://tis2web.service.gm.com/tis2web and enter the vehicle's 17 character Vehicle Identification Number (VIN) and select 'Get CAL ID’.
You can then compare the latest part number with the actual number installed on the vehicle to determine if a reprogram is needed.
The Service Programming System (SPS) application is part of the TIS2Web system. To program an ECU, the SPS application must communicate with the vehicle control modules using the proper J2534 programming interface tool.
The following are the supported interface tools:
The Tech 2 supports model years 1996 and beyond. With the addition of the CAN Diagnostic Interface (CANdi) module, Tech 2 is fully backward compatible with current Tech 2 functionality and operates transparently when diagnosing non-CAN-equipped vehicles.
Servicing the next generation Global A vehicles will require the diagnostic software, GDS2, Global Diagnostic System 2 running on a local PC device while the MDI is connected to the vehicle. The GM MDI is the Global Diagnostic tool for future vehicles starting with Global A vehicles.
The GM MDI was introduced in the fall of 2007 for Pass-Thru programming and offers faster programming speed. It can be used to perform Pass-Thru programming on all vehicles built since 1996 and into the future. Click here to view a list of GDS supported vehicles.
