Code: Hybrid/EV Battery Pack Capacity Learn The Hybrid/EV Battery Pack Capacity Learn procedure must be completed when the following components are replaced: • Hybrid/EV Powertrain Control Module 2 • Hybrid/EV Battery Energy Control Module • Hybrid/EV Battery Interface Control Module • Hybrid/EV Battery Pack The Hybrid/EV Powertrain Control Module 2 Capacity Learn procedure can be completed with a scan tool using the following steps: 1. Install the scan tool to the data link connector. 2. Ignition ON, engine OFF. 3. Select Hybrid/EV Battery Pack Capacity Reset in the Hybrid/EV Powertrain Control Module 2 Control Functions list 4. Follow the scan tool directions to complete the procedure. 5. Select Hybrid/EV Battery Pack Capacity Learn in the Hybrid/EV Powertrain Control Module 2 Control Functions list 6. Follow the scan tool directions to complete the procedure. 7. Clear any DTCs that may be set.

Wondering what that salvaged Li-ion battery section is actually wired into. Have you actually hooked up to the HV battery pack on that Gen1?There are 96 cell groups in the hybrid battery assembly. These cell groups are electrically connected in series. The battery cell groups are joined to form three sections. Are these additional sections connected in series with the existing HV battery?The Battery Energy Control Module monitors the voltage of the 96 battery cell groups through four Hybrid Battery Interface Control Modules and determines when a fault condition is present. The Hybrid Powertrain Control Module 2 is the host controller for DTC information. Could these 'extra' batteries even be monitored for faults?Appears not to be very safe since the HV would be exposed in the hatch area and there also would be no liquid cooling.I'm afraid it is not as simple as just wiring more HV batteries in series otherwise other folks would be accomplishing this.You would need the EL-50332 Hybrid/EV Battery Service Tool lined above in order to perform the proper cell balancing procedure for these extra battery sections.So even if these battery sections are wired correctly and then balanced, you would still need to perform the Battery Pack Capacity Learn procedure before the Gen1 could recognize the increased battery capacity if it even could at all....
