WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2018 Porsche Cayenne, 2017 Porsche Cayenne, 2016 Porsche Cayenne, 2015 Porsche Cayenne, and 2014 Porsche Cayenne. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Voltage peaks
- Risk of damage to load or to the control unit
→ Remove the ignition key and switch off load before disconnecting or removing load.
Information
- The new lines will be secured to the fastening points for the old lines .
- The old wire harness remains installed in the vehicle .
- The old wire harness will only be disconnected/unplugged directly at the connected components .
Information
- When installing the wire harness, make sure the insulation of the line is not damaged .
Information
The range of spare parts available for optical waveguides depends on the vehicle equipment. Depending on the vehicle equipment, there is a specific set containing the individual optical waveguides.
Select the required optical waveguide and remove it from the set.
Information
Before routing a new optical waveguide:
- Visually check the locks, connector housing and contacts for damage .
- Replace damaged parts if necessary .
- Cut optical contacts off the damaged optical waveguide, insulate it and tie it to the main wire harness.
- Route the new optical waveguide along the main wire harness, guide it through the existing cable ducts and tie it to the main wire harness using tie-wraps (shown as an example).
- Plug in plug connection for optical waveguide at the TV tuner until it engages securely.
- Plug in plug connection for optical waveguide -3- at the PCM system -arrow B- and make sure that the locking mechanism engages securely. Connecting electric plug connections -4, 5, 6, 7, 8- .
