1. A method in a telematics device coupled to a vehicle communications bus of a vehicle, the method comprising:
detecting a vehicle starting event;
in response to detecting the vehicle starting event:
sending, over the vehicle communications bus, a first plurality of requests for a first plurality of parameters of a first set of parameters, after the vehicle starting event and before an expiry of a requests-off duration that started at the vehicle starting event, to a first plurality of electronic control units (ECUs) of the vehicle;
refraining from sending a second plurality of requests for a second plurality of parameters of a second set of parameters, to a second plurality of ECUs of the vehicle, for the requests-off duration; and
in response to an expiry of the requests-off duration, sending, over the vehicle communications bus, the second plurality of requests for the second plurality of parameters to the second plurality of ECUs of the vehicle.
