History
Module identification not read.
Recalls
Not looked up. e500 recalls fetches them by model year (no VIN is sent).
Fault codes
Read from every module and never cleared. A module also lists every check it runs; a code counts as a fault only if it has failed, is pending or is confirmed. "Active now" means it failed in this drive cycle.
| Module | Code | State | Records |
|---|---|---|---|
| Battery controller (BPCM) | P0AA6-00Hybrid/EV battery voltage system isolation fault | Storedconfirmed, failed since clear | 1 |

Method and evidence
Every figure comes from the car, read with standard read-only diagnostic requests. How each raw value is decoded, and why we believe it:
| Reading | Module · data ID | Evidence |
|---|---|---|
| Cell voltages | 44 · A100–A108 | own capture 2026-11-07: 97 u16 mV values; agree with A609-A60B to 1 mV |
| True charge | 44 · A602 | own capture 2026-11-07: fits 5 dash readings within 0.4 %; 240 V energy check 6.5 kW |
| Highest cell (controller) | 44 · A609 | own capture 2026-11-07 |
| Lowest cell (controller) | 44 · A60A | own capture 2026-11-07 |
| Average cell (controller) | 44 · A60B | own capture 2026-11-07 |
| Pack current | 44 · A012 | own capture 2026-11-07: s16 / 20, negative = charging; -15.45 A x 393 V = 6.1 kW steady on the 6.6 kW charger, ~0.5 A at rest. Scale lead: OBDb gen-2 current (/20) |
| Capacity (controller's figure) | 44 · A625 | own capture 2026-11-07: u16 / 10 = 37.9 Ah, same as module 42 DID 2050; the controller's charge moved 36.4-37.9 Ah per 100 % against the measured current |
| Charge in since controller fitted | 44 · A615 | own capture 2026-11-07: u24 / 10; rose 7.7 Ah while the measured current gave 7.71 Ah |
| Charge out since controller fitted | 44 · A616 | own capture 2026-11-07: u24 / 10, companion of A615; still while charging |
| Battery module temperatures | 44 · A200 | own capture 2026-11-07: 18 x u8 - 40; min/max/mean equal module 42 DIDs 205E-2060. Layout lead: OBDb gen-2 A200 |
Not read, so not in this report: fault codes, insulation resistance, the controller's history of temperature and charge levels, and anything a dealer tool would need security access for. Assumptions: new capacity 60–67 Ah (published specs disagree), 3.5–4.5 mi/kWh for range.
