DTC P16BE: Starter Relay 1 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 exceeds a set voltage even when the starter cut relay output (STRLY) is turned off, the PCM detects the 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.

Malfunction Threshold
One of these conditions occurs:
- The terminal voltage of the STRLD exceeds 3.0 V for at least 5 seconds when the starter cut relay output is turned off.
- The terminal voltage of the STRLD is 2.4 V to 2.6 V for at least 0.8 seconds when the starter cut relay output is turned on.
