Poor connection detector bar
- • The poor connection detector bar inside the SAS unit connector detects the poor connection of the SAS unit connector.
- • The poor connection detector circuit in the SAS unit measures the resistance between the poor connection detector bar terminals. When it detects there is on continuity between the poor connection detector bar terminal, the poor connection detector circuit determines there is a poor connection and indicates that the DTC should be output.
