Disconnecting optical waveguide
Note. Observe the general information on optical waveguides. --> 97 72 IN Optical waveguide (LWL) - MOST bus - as of MY 2005 (All Models) . Risk of destruction when removing electric components with the ignition on.
> Switch off ignition and remove ignition key.
1.
Scheme 262
2. Release the connectors of the damaged optical waveguides on the affected components -Arrow a- and disconnect them. The illustration shows the connector on the CD changer as an example. (Scheme 262)
3. Cut off the connector of the damaged optical waveguide, isolate it and tie it to the main wire harness.
Scheme 263
1. Open the secondary locking mechanism using the press-out and unlocking tools for tab and round plug connectors of all sizes NR.155 . Insert the tool in the opening provided and lift the locking mechanism. The locking mechanism engages in the upper position.
Scheme 264
2. Position the press-out and unlocking tools for tab and round plug connectors of all sizes NR.155 on the primary locking mechanism and lift the locking mechanism.
A - Optical contact, grey
B - Optical contact, black
3. Carefully pull on the optical waveguide -A and B- in -direction of arrow-. If it is not possible to pull out the optical waveguide, check again if the secondary locking mechanism is completely released and if the primary locking mechanism is raised sufficiently. (Scheme 264)
Perform visual inspection of locking mechanisms, connector housings and contacts for possible damage, and exchange the damaged parts, if necessary.
