4. Registering A New Battery With Tool32 Via OBD2 Bluetooth

Registering a new battery is crucial for BMWs to ensure proper charging and prolong battery life.

4.1. Why Battery Registration Is Important

BMWs use an intelligent battery management system (IBS) that adapts the charging rate based on the battery’s age and type. When a new battery is installed, the system needs to be reset to prevent overcharging or undercharging, which can lead to premature battery failure.

4.2. Step-By-Step Guide To Battery Registration

1. Connect To The Vehicle: Follow the steps in Section 3 to connect Tool32 to your BMW via the OBD2 Bluetooth adapter.
2. Load The DME File:
   • In Tool32, go to File > Load SGBD.
   • Navigate to the ECU folder (C:EDIABASECU) and select the appropriate .PRG file for your engine control unit (DME). The file name will vary depending on your engine type (e.g., MSV70.PRG for N52 engines, MSD80.PRG for N43/N53/N54 engines). Refer to Appendix A of the original document for a detailed list.
3. Select The Registration Job:
   • Scroll through the list of jobs until you find steuern_batterietausch_registri. This job is specifically for registering a new battery.
4. Run The Job:
   • Select the steuern_batterietausch_registri job.
   • Go to the Jobs menu and select Run Job Once (or Job Einmal Ausfuhren in German).
5. Verify The Result:
   • After running the job, verify that the operation reports “Okay.” This indicates that the battery registration was successful.

4.3. Common Errors And How To Resolve Them

• Error: IFH-0018: INITIALIZATION ERROR: This error typically indicates a communication problem. Check your OBD2 adapter connection, COM port settings, and EDIABAS configuration.
• Error: Job Not Found: Ensure you have loaded the correct .PRG file for your DME.
• Error: Operation Failed: This can occur if the battery registration job is not compatible with your vehicle’s software version. Try updating your BMW Standard Tools or consult a BMW specialist.

4.4. Verifying Successful Battery Registration

To verify that the battery registration was successful:

1. Use INPA:
   • Open the INPA program.
   • Navigate to your vehicle model, engine, and then the PM-IBS section.
   • Check the battery capacity (Ah) reading to ensure it matches the new battery’s specifications.
2. Check Voltage Readings: Monitor the charging voltage with a multimeter or through INPA to ensure it is within the correct range for the new battery type.

5. Coding A New Battery Type Or Capacity

If you replace your battery with a different type (e.g., wet-cell to AGM) or capacity (Ah), you need to code the changes to the vehicle’s ECU.

5.1. Understanding Battery Coding

Coding informs the car’s charging system about the new battery type and capacity. AGM batteries require a different charging profile than wet-cell batteries, and the capacity affects the charging current. Proper coding prevents overcharging or undercharging, maximizing battery life.

5.2. Methods For Coding Battery Changes

Several methods can be used to code battery changes:

1. Carly App: A user-friendly app for iOS and Android that simplifies battery coding.

   • Verify that the coding ended successfully.
6. Repeat For NFRM/FRM:
   • Repeat the process for the NFRM/FRM module.

5.4. Updating The Vehicle Order (VO)

The vehicle order (VO) stores information about the car’s original configuration, including the battery type. Updating the VO ensures that future coding and programming changes are based on the correct battery information.

1. Open NCS Expert: Follow steps 1-4 from the NCS Expert coding guide.
2. Enter FA:
   • Press F6 (Back).
   • Press F1 (VIN/ZCS/FA).
   • Press F2 (Enter FA).
   • Select your chassis and click OK.
3. Edit The VO:
   • In the “Enter FA” window, scroll to find the VO for the old battery (e.g., -B090).
   • Highlight the old battery VO and press Delete.
   • Enter the new battery type (e.g., -A080 for an 80Ah AGM battery) in the “Attribute” box. Refer to Appendix B of the original document for possible values.
   • Click “Add” and then OK.
4. Write The VO:
   • Press F6 (Back).
   • Press F4 (Process ECU).
   • Select CAS and click OK.
   • Press F2 (Change Job) and select “FA_Write.” Click OK.
   • Press F3 (Execute Job).
   • Verify that the write is complete.
5. Repeat For NFRM/FRM:
   • Repeat the process for the NFRM/FRM module.
6. Code The Car:
   • Use NCS Expert to code the car based on the new VO settings. This will automatically write the battery capacity and type settings to the various modules.
