The PCM

Low voltage + BB unit PCM (P1562)

The PCM monitors the voltage of the positive terminal of the battery on the output unit 2Z PCM. If the PCM detects that the voltage of the positive terminal of the battery is lower than 2.5 V for 2 seconds, it considers that the backup voltage circuit has a malfunction.
