Separate the Connector
Separate the connector
WARNING: SRS Nor cable repair or other repair work may be carried out on the SRS wiring. For repairs to the SRS system refer to the Restraint Systems.
If the connector halves (socket housing and pin housing) are connected together or if the connector is connected to a component, then the connector halves must first be separated.
General instructions
Note that these are general instructions, variations can occur in practice. Regard the examples shown and the procedures described as guidelines.
Types of catches and locks
The connector halves are connected to each other by different types of lock tabs/eyes. Separation
NOTE: Never pull the cables when separating. Hold the connector halves.
Active locking
For active locking Systems (Fig. A) a catch must be pressed down to release the lock.
Passive locking
For passive locking systems (Fig. B) the catch is released when force is applied to separate the connector halves.
Reconnecting
The connector halves are physically located with a guide pin. Always turn the connector halves to the correct position when reconnecting. Check that connector halves lock properly into each other.
Secondary locking
The cable terminals are retained in the housing cavities by different forms of primary locking and secondary locking. This describes how the different secondary locking Systems on housing types are opened. If there is no secondary locking on the housing this can be ignored.
There are housings with and without secondary locking. In order to decide if the housing has secondary locking and if it has of which type, refer to the housings illustrated at Secondary locking - socket type, When secondary locking is of the lid type and When secondary locking is of the cavity cover type.
Housing with secondary locking
To replace a cable terminal the secondary locking must first be opened.
The following procedures describe how different types of secondary locking can he released to open a housing
- Secondary locking socket/housing retainer type
- Secondary locking lid/catch cover
- Secondary locking cavity cover /locking plate
More examples of procedures for opening secondary locking can be found in connectors some examples of methods.
Tools
Use a thin screwdriver with a blade 3 - 4 mm wide.
Secondary locking - socket type
Open the secondary locking as shown if it is of the socket/housing retainer type
General instructions
Note that these are general instructions, variations can occur in practice.
Regard the examples shown and the procedures described as guidelines.
Release socket/housing retainer
Use a thin screwdriver with a blade 3 - 4 mm wide.
- Work the locking catches/eyes carefully loose on the socket or on the housing.
The number of locking catches/eyes and their location varies on different housings. There can also be variations between pin sizes in the housing types.
NOTE: Take care that the locking catches/eyes are not broken off when releasing the socket.
Remove
- Remove socket (and pull it back on the cables).
Proceed
To replace a cable terminal the next step is to remove the old cable terminal in the housing.
When secondary locking is of the lid type.
To open a housing secondary locking of the locking lid/catch type proceed as follows
General instructions
Note that these are general instructions, variations can occur in practice.
Regard the examples shown and the procedures described as guidelines.
Open locking lid/catch
Use a thin screwdriver with a blade 3 - 4 mm wide. Work the locking catches/eyes carefully loose on the locking lid or on the housing.
The number of locking catches/eyes and their location varies on different housings. There can also be variations between pin sizes in the housing types.
CAUTION: Take care that the locking catches/eyes are not broken off when releasing the lid.
- Unlock and open the locking lid
In multi-pin housings there can be separate locking lid for the upper cavity row and the lower. Only open the locking lid which is locking the cable terminal which is to be replaced.
Proceed
For replacement of a cable terminal the next step is to remove the old cable terminal which is in the housing.
When secondary locking is of the cavity cover type
To open a housing secondary locking when it is of the cavity cover/locking plate type, proceed as follows
General instructions
Note that these are general instructions, variations can occur m practice.
Regard the examples shown and the procedures described as guidelines.
Open cavity cover/locking plate
For some housings a small, thin screwdriver can be used, for others no tool is required.
The secondary locking on this type of housing is released by setting the cavity cover/locking plate in the open position. There are two positions, open or closed.
- Lift up, push or unclip from the locking plate
A "click" can be heard when the plate unlocks and is in the open position.
NOTE: If the housing has a long, narrow locking plate check that it opens completely and not only along one edge. Work loose the locking plate along one entire long side.
Other examples of cavity cover/locking plates
More examples of housings with cavity cover/locking plate and procedures for opening them can be found in connectors, some examples of methods.
Proceed
To replace a cable terminal the next step is to remove the old cable terminal located in the housing.
- Proceed to extracting the cable terminal from the housing.
