MS41.1 - ASC Interfaces

The MS41.1 Control Module is linked to the ASC control module through three signal lines for ASC regulation. The three signals are switched high/low input requests for power reduction/drag torque reduction. The signal paths follow the same logic as the Bosch engine management systems including:

- S-EML - Signal to the MS41.1 Control Module of throttle regulation
- S-MSR (ZWV) - Signal request to the MS41.1 Control Module for ignition timing retard and idle speed boost
- S-ASC (ZA) - Signal request to the MS41.1 Control Module for fade out of ignition/injection and idle speed boost
