Troubleshooting-Data: FH 12 380 Model: Motor: D12A 380 / ABS-ASR 4 Channel

This document provides troubleshooting values for an ABS system on a vehicle. It lists various components in the ABS system and their corresponding pins or terminals in the connector. It provides the normal voltage or resistance values for each component under different ignition and operating conditions, such as with the ignition on or off or when a wheel is spun at approximately 30 rpm. The values are to be used as guidelines to diagnose issues in the ABS system components.
