TBF, most cars do that now a days. Car brands don’t make their own ABS systems, they buy them from manufacturers like Bosh and Denso; and they all work on the “CAMBUS” standard, meaning that all sensors talk to each other over a network. Normally these systems light up an individual diagnostics light to let you know if there’s a problem detected (low brake pad / fluid indicator, parking brake, ABS light) so to differentiate when there’s a system error such as a sensor that can’t communicate it lights them all up at the same time to let you know.
For example my 06 G35 did that for a stupid brake sensor, cost me endless hours of troubleshooting to pinpoint.
