DTC P16BE: Starter Cut Relay 1 Malfunction: General Description

To prevent the starter from continuing to run 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 exceeds a set voltage even when the starter cut relay output (STRLY) is turned off, the powertrain control module (PCM) detects a starter cut relay 1 turn on switching failure and a DTC is stored. When the starter is turned on, but the STRLD terminal input voltage does not exceed the upper or lower limit, a simultaneous failure of both starter cut relays or the STRLD open circuit is detected.
