Vehicle Data Catalog

A consolidated reference of confirmed vehicle properties and Geely adaptation layer function IDs on the IHU629G. All properties are accessed via CarPropertyManager inside the installed APK. For detailed probing methodologies, logs, and historical investigations, see field-catalog.md.

Powertrain & Driving

Property / Function ID	Name	Type	Access	Values / Scaling	Notes
`570491136`	DRIVE	int	RW	Eco=`570491137`, Comfort=`570491138`, Sport=`570491139`	Areas `0, 1`. Writes require vehicle in ready/drive state to hold.
`537003264`	REGEN	int	RW	Low=`537003265`, Mid=`537003266`, High=`537003267`	Areas `0, 1`.
`289408001`	GEAR_SELECTION	int	R	`1`=N, `2`=R, `4`=P, `8`=D	Adapted value (`VehicleGear` enum). Alias: `0x2140800f`.
`291504647`	PERF_VEHICLE_SPEED	float	R	km/h	Area `0`. Already scaled (`div=1`).
`289407492`	ODOMETER	float	R	km	Cumulative vehicle distance. Area `0/1`.
`658548345`	TRIP_KM	float	R	km	Current trip distance. Area `0/1`.
`557884450`	CRUISE_STATE	float	R	`0.0`=OFF, `1.0`=ARMED, `7.0`=ACTIVE	Area `0`. Integer alias: `557887630`. Set speed property remains unmapped.
`557885463`	PARK_MODE	int	RW	`0`=off; `0x201B0100 \\| duration`	Duration: `0x02`=30m, `0x04`=1h, `0x06`=2h, `0x08`=3h, `0x0A`=4h, `0x0C`=5h, `0x13`=unlimited.

Battery & Charging

Property / Function ID	Name	Type	Access	Values / Scaling	Notes
`557885165`	BATTERY_SOC	float	R	% (0..100)	Adaptation layer pre-scaled float. Area `0/1`.
`289407752`	RANGE	float	R	km	Estimated remaining range. Area `0/1`.
`557887621`	PORT_CONNECTED	int	R	`3`=connected, `0`=disconnected	Physical plug connection status. Reliable indicator independent of charging current.
`605029888`	CHARGE_LIMIT	int	RW	5..32 A	User-selectable charge current limit. Area `0/1`.
`605291008`	CHARGE_CURRENT	float	R	A	Actual charging current. Zeroed when not actively charging to avoid residual sense drift.
`605290752`	CHARGE_VOLTAGE	float	R	V	Charging voltage. Zeroed when not actively charging.
`605028608`	CHARGE_SWITCH	int	RW	`609`=STOP, `610`=RESTART, `611`=START_NOW	Explicit charge control commands. Area `0`.

Climate Control (HVAC)

Property / Function ID	Name	Type	Access	Values / Scaling	Notes
`354419984`	HVAC_POWER_ON	boolean	RW	true / false	Master AC power switch. Adapted boolean (raw value is `2` when off).
`354419973`	HVAC_AC_ON	boolean	RW	true / false	AC compressor enable.
`0x15600503`	ZONED_TEMP_SETPOINT	float	RW	16..32 °C (`°C = 17 + raw / 2`)	Target setpoint. Quantized to 1 °C steps; writes of half-degrees read back truncated. Area 4 is not physical (reverts to synced value). The center point is a mode boundary crossing between heating and cooling.
`557884279`	AC_AMBIENT_TEMP	int	R	°C: `(raw - 80) / 2`	Outside ambient temperature sensor. Area `0`.
`356517120`	HVAC_FAN_SPEED	int	RW	0..8	Blower speed: `0`=off, `1`..`8` active levels. Alias: `557846559` (`0x2140101F`).
`557846560`	ZONED_FAN_DIRECTION	int	RW	Bitmask: `1`=FACE, `2`=FLOOR, `3`=FACE\|FLOOR, `4`=DEFROST, `6`=DEFROST\|FLOOR	Area parameter is ignored. Value `5` (DEFROST+FACE) is rejected by vehicle. Alias: `356517121` (`0x15400501`).
`354419976`	RECIRCULATION	boolean	RW	true / false	Cabin air recirculation (`0x15200508`).
`354419978`	HVAC_AUTO_ON	boolean	RW	NOOP	Accepts writes with no effect; do not delegate fan or mode logic to it. (`354419975` is `MAX_DEFROST`, not AUTO).
`HVAC_IN_OUT_TEMP`	CABIN_TEMP	-	-	NOT_AVAILABLE	Vent and cabin temperatures are not exposed via VHAL.

Cabin Lighting & Interior

Property / Function ID	Name	Type	Access	Values / Scaling	Notes
`537528576`	AMBIENT_COLOR	int	RW	`0xRRGGBB` hex color	Area candidates `{5, 0, 1}` must be swept and read back to confirm execution.
`704708864`	AMBIENT_BRIGHTNESS	int	RW	0..20	`0`=off. Setting brightness to non-zero is required before color writes will take effect.
