Plausibility Error in Sensor Circuit 2 (External/Internal)

What does 2 mean?

This fault indicates either an external plausibility error in sensor circuit 2 or that internal diagnostics are active, signaling an internal error. This state occurs when both sensor circuits 1 and 2 are active, the reset/start circuit is activated, and the segment circuit is open. It suggests an inconsistency in sensor input logic or an internal device malfunction affecting functional safety.

• External plausibility error detected in sensor circuit 2
• Internal diagnostics active, indicating an internal device issue

Click steps to track your progress.

1. 1

   For external errors: Check the affected sensor circuit 2 for proper operation and signal integrity

2. 2

   For internal errors: Perform a power down reset (switch off and then re-apply operating voltage)

3. 3

   After addressing the error and performing any power down reset, conduct a subsequent function test
