MOST Ring, Check Stability

Most Bus:checking Ring Stability

The test module enables a conclusion as to whether the MOST ring is closed or open. It can provide two results:
- The ring is closed at the moment of the check. In this case, the ring is functional (or sporadically interrupted).
- The ring is open at the moment of the check. In this case, the ring is permanently interrupted.

Exception: If only the Multi Audio System Controller (or Car Communication Computer) and Head Up display are fitted in the MOST ring, the stability of the ring cannot be checked at this time.
