TRACTION_CONTROL_ACTIVE

What it is

Traction Control is active

Set to true when traction control (TC) is active. Reset to false when TC is off. This property may be intermittently set (pulsing) based on the real-time state of the TC system.

How the ID is built

A property ID is a 32-bit value packing four fields. Reading 0x1120040b apart:

Field	Mask	Value	Means
Group	0xf0000000	0x10000000	SYSTEM
Area	0x0f000000	0x01000000	GLOBAL
Type	0x00ff0000	0x00200000	BOOLEAN
Ordinal	0x0000ffff	0x0000040b	0x40b

Reading it from an app

CarPropertyManager mgr = (CarPropertyManager)
        car.getCarManager(Car.PROPERTY_SERVICE);

boolean value =
        mgr.getBooleanProperty(VehiclePropertyIds.TRACTION_CONTROL_ACTIVE, 0);

This property is read-only — writes are rejected. It fires a callback whenever the value changes.
