Interpreted Parameters

These parameters are created as a result of received vehicle parameters. For example, an Event is a result of the ABS parameter becoming enabled.

Parameter	Description
Event	An alert triggered by a parameter or multiple parameters meeting certain criteria.
ScanPro	Usage of the ScanPro API request will be available here for the time it was requested.
Trip	A log of vehicle information from key on to key off.
DTC Freeze Frame	Collection of parameters from the time a code was set.

Events

Events are returned as arrays that hold every event that occurred over the requested time range. Every event type will be returned, and if no event of that type occurred over the requested time frame, the array will be empty.

Some events are only possible with advanced parameter data. The corresponding advanced data required will be specified below.

Event	Description
ABS	Braking event that triggered the anit-lock braking system of the vehicle. Requires the stability parameter.
Traction	Events where the traction control system has triggered. Requires the traction parameter.
Stability	Events where electronic stability control has triggered. Requires the stability parameter.
Swerve	Detected a sharp turn. Requires the steering wheel angle.
Low Tire Pressure	Triggered when any one tire's pressure falls below 150 kPa for more than 3 minutes. Requires the tire pressure parameter. Will work for each individual tire that is supported.
Driver Belt Unbuckled	Events triggered by the driver belt parameter being in state UNBUCKLED while driving faster than 10 kph. Requires the driver belt parameter.
Passenger Belt Unbuckled	Events triggered by the passenger belt parameter being in state UNBUCKLED while driving faster than 10 KPH. Requires both passenger belt and passenger occupancy parameters.
DTC	When a DTC sets an event is created at that point in time. A new event will not be created unless the DTC is cleared or becomes inactive, and becomes active again after at least two weeks.
Goodyear tire intelligence	If Goodyear tire intelligence is enabled, an event is created when and if Goodyear has determined it is time to change your tires.
FailSafe Battery Health	If FailSafe is enabled, an event is created when FailSafe has determined your 12 volt battery needs to be replaced.
Oil Life Low	Events where oil life has fallen below 25%, 10%, or reached 0%. Requires oil life parameter.
Emissions Test Result	There are two types of emissions events specified by a detail parameter. The first is a notification that all emissions monitors have passed successfully. The second is a warning that it has been a week since VOYO has been connected and emissions monitors have still not passed.
Failed Emissions Test	Events where emissions testing has failed.
Seat Belt Usage	Events triggered by the driver or passenger of the vehicle driving faster than 10 kph with their seatbelt unbuckled. Requires driver belt parameter or both passenger belt and passenger occupancy parameters.
Vehicle Left Idling	Events triggered by the vehicle being immobile for more than 3 minutes with the engine running.

All service notification events require the user to specify a number of miles the vehicle must travel before triggering. An event is created at 25%, 10%, and 0% of the mileage remaining.

Event
Service Notification - Oil Life
Service Notification - Tire Replacement
Service Notification - Tire Service
Service Notification - Vehicle Service

Lookout events are alerts that indicate something has been left on or open after leaving a vehicle. For example, a Headlights Left On Lookout event will trigger when walking away from the vehicle while the headlights are still on. All Lookout events require a BLE (Bluetooth Low Energy) connection. and the user must walk far enough away to become disconnected from VOYO device to trigger the event.

Event	Description
Ignition Left On	Triggered by walking away from the vehicle while the vehicle ignition is on.
Engine Left On	Triggered by walking away from the vehicle while the engine is running.
Headlights Left On	Triggered by walking away from the vehicle while the headlights are on.
Trunk Left Open	Triggered by walking away from the vehicle while the trunk is open.
Hood Left Open	Triggered by walking away from the vehicle while the hood is open.
Door Left Open	Triggered by walking away from the vehicle while any door is open.

Requires firmware version r7456 or greater:

Event	Description
Hard Braking	Accelerometer detected the vehicle came to a stop too quickly.
Hard Cornering	Accelerometer detected the vehicle took a sharp turn.
Hard Acceleration	Accelerometer detected the vehicle accelerated too quickly.

The following events exist historically but are temporarily disabled:

Event
Goodyear tire intelligence
FailSafe battery health

The following events exists historically but have been replaced:

Event	Description
Driver Belt Unbuckled	Replaced by Seat Belt Usage.
Passenger Belt Unbuckled	Replaced by Seat Belt Usage.

Parameter	Description
max_gs	The normalized force that caused the event to trigger in units of "g-force".

name	String representation of this DTC.
short	Short description of the DTC.
long	Longer and more detailed description of the DTC.
severity	Severity of the DTC, the larger the value, the more critical.

Trips

Trips are created objects that aggregate relevant information from the time the vehicle's engine starts to when it stops (supports hybrid and electric vehicles).

Parameter	Description
start_time	Unix timestamp for when the trip started.
end_time	Unix timestamp for when the trip ended.
distance_driven	Total distance driven from start to end of trip. Reported in Km. Calculated using vehicle speed - not odometer.
fuel_used	Total fuel used from start to end of trip.
stop_time	Amount of time in seconds the vehicle was not moving.
min_crank_voltage	Lowest 12 V battery voltage when trip started.
resting_voltage	Average 12 V battery voltage from start to end of trip.

DTC Freeze Frame

Some DTCs store a collection of parameters from the time the code was set. DTC Freeze Frame is a collection of any and all of that information retrieved for the requested time frame.

Parameter	Description
time	Time the freeze frame was reported.
code	DTC name.
PIDs	An array of parameter data taken at the time the DTC was created.

PID

Parameter	Description
PID	PID as a hex string. For example, vehicle speed would be "0x0D".
data	String including the reported data and attributed unit. For example, vehicle speed would be "0 kph".

Example

Parameter data is collected at different rates. As a result, the "ID-data" array will contain arrays of a varying number of available parameters.
