In that meantime and during that time frame, you can have a Low V. condition..... specially when using other power consumers..............
Something to check.
The PSI tire thing I mention is more remote, but the ASR systems are dependant to tire circumference b/c all 4 wheels get compared ...so, a soft, cold tire can in fact be out of C when read by the modules check, but as the car is driven, the PSI can come up from running of the tire and it may be just enough to bring the Circ back into match with the other three.
It would have to be borderline to begin with and it would have to be cold/warm enough to make the psi difference. It does not take long on asphalt at speed with a low/cold tire to warm up ..and that temp difference effects the PSI....
which , under the right conditions, can change the tires C sizing...
