Terminal Housings, Release and Disassembly, General Information
CAUTION!
Risk of injury.
‹› Some tools are supplied with a tool safety clip, which is slid over the tool points after using the tool, in order to protect other workers
from injuries and tool points from damage.
‹› Observe general notes for repairs on the vehicle electrical system => [ Vehicle Electrical System, General Information ] See: Wiring Harnesses
and Connectors.
‹› Always use the release tools intended for the releasing process. Under no circumstances may terminals be pulled forcefully out of terminal
housings.
‹› Damaged contact housings must always be replaced.
‹› Small screwdrivers may be used as an aid to release the secondary locks.
‹› Chamber/pin assignment is located partially stamped in on secondary lock or rear side of terminal housing.
‹› Detailed information on component locations of harness connectors.
‹› Allocation of the correct release tool to the respective retainers => (VAS 1978/35) instructions.
Secondary Lock
‹› The secondary lock is a housing securing mechanism (second locking mechanism) that secures all wires in one terminal housing. If a secondary
lock is installed at a terminal housing, it must always be opened or removed using specified tool before releasing and pulling out individual crimp
contacts.
‹› Secondary lock is distinguished by a different color from the rest of the contact housing. It simplifies recognizing the secondary lock and clarifies
its function.
‹› The shapes of the terminal housings depicted here are only a selection which, as an example, should make clear the various functions of the
secondary lock.
