Advanced Diagnostics - 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 stores a DTC. 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 second when the starter cut relay output is turned on.

Diagnosis Details

Conditions for setting the DTC
When a malfunction is detected, a Pending DTC, a Confirmed DTC, and the freeze data are stored in the PCM memory. The MIL does not come on.
