A power distribution box (PDB) includes relays to connect a vehicle battery to corresponding electronic control units (ECUs) of a vehicle. A processor is programmed to instruct the PDB via a control interface to cause one of the relays to power a target ECU, send a sleep command over a vehicle bus to cause powered ECUs other than the target ECU to sleep, and install a software update to the target ECU.
