Beyond the battery.
Each subsystem with a read path gets its own page: climate, drive units, charging, power, TCAM, steering, service schedule, GPS and the vehicle option map.
On this page


Measured, not manufactured
Each field on these pages is a typed observation: value, state, source and decoder version, or a recorded failure. A DID that refuses with a negative response code produces a refusal, not a zero. A parked car with a drifting rotor reading is classified stationary at the display layer without touching the raw value.
Consistency checks
Ten checks compare related readings from the car, including pack voltage against the cell sum, reported power against calculated power and compressor state against refrigerant pressure. They run on current battery, motor and climate data. If an input is missing, the result says there is not enough data; a mismatch produces a warning for you to investigate, not a fault diagnosis.
Boundaries
Cable-rating decoding stays experimental. Option indexes the catalogue does not name remain numeric. Unknown layouts are kept as exploratory evidence rather than turned into a verdict about your car.
- Climate
Heat pump loop, compressor state, coolant temperatures per loop with the deltas computed, condenser against evaporator.
- Drive units
Front and rear inverter telemetry (IHFA, IEM) with a side-by-side comparison: temperature, voltage, coolant, torque split. A side that did not answer stays empty, never zero.
- Charging
Socket lock, cable capability, on-board charger state, plus a charge-limitation diagnosis that attributes a capped charge from evidence or declines to.
- Power
Charger AC input and DC-DC converter, with the 12 V rail tracked against its state of charge.
- TCAM
Emergency backup-battery health with a length-discriminated layout, raw byte evidence and a digest; GNSS fix only on an explicit button press.
- Steering
Steering angle sensor: angle, angular velocity, calibration state. Read-only; zeroing is not part of it.
- Service schedule
DIM intervals with mileage and time countdowns, and a flag when a counter moves somewhere it should not.
- Configuration
The CEM 256-entry option map with live search, plus the factory build record: anchor VIN, option codes, paint and interior trim.
- Sleep drain
12 V quiescent current history and module wake-state logs for parasitic-drain chasing.
