BMW 7 Series: Notes On Handling Wiring Harnesses And Cables

The following applies in general

To avoid damage, observe the following instructions:

• Avoid compressive and tensile loads
• To ensure professional repairs, perform repair work only with BMW-approved or recommended special tools and spare parts
• Make sure cables are laid without kinks or abrasions
• Ensure non-contacting routing at sharp-edged body parts; use edge protection if necessary
• Secure additionally laid cables/leads with cable ties

The following additionally applies

Shielded lines (coaxial lines):

IMPORTANT: Shielded lines may not be repaired!

• This may lead to indifferences in noise radiation and interference immunity at contact points in the shield
• To satisfy the requirements of the type approval, it is essential to replace shielded cables completely

Fibre-optic cable:

NOTE: Fibre-optic cables are colored differently as follows:

• G reen = MOST (M edia O riented S ystems T ransport) optical fibre
• Yellow = ISIS (I ntelligent S afety I ntegration S ystem) optical fibre
• Orange=repair fibre-optic cables

IMPORTANT:

• Optical fibres may only reveal one separation point (bridge); renew optical fibre if necessary
• Smallest permissible bending radius is 25 mm
• Avoid effects of heat > or = 85 º

Treating cables and fibre-optic cables.

FlexRay:

It is possible to repair the FlexRay. In the event of damage, the cables can be joined with conventional BUTT CONNECTORS AND HEAT-SHRINK HOSES.

NOTE:

• FlexRay lines may only reveal one separation point (bride); renew complete line if necessary
• The cable is a twisted cable. If possible, maintain twisted cable after repair

Airbag lines:
