DTC P16BD: Starter Relay 2 Malfunction: General Description

To prevent the starter from continuing to rotate due to a switching failure of the starter cut relay, two starter cut relays are connected in series.

When the input voltage of the STRLD terminal drops to a set voltage even when the starter cut relay output (STRLY) is turned off, the PCM detects a malfunction of the starter cut relay 2 (ST CUT) and a DTC is stored.
