DTC P16BD: Starter Cut Relay 2 Malfunction (A/T Model)




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 powertrain control module (PCM) detects a malfunction of starter cut relay 2 (ST CUT) and a DTC is stored.
