Disconnecting Main Wire Harness In Plenum Panel

NOTE: Incorrect handling of main wire harness 
  • Risk of damage to lines 

    → The main wire harness contains all airbag lines, antenna lines and optical waveguides.

    → The main wire harness must not be separated and is always replaced as a complete wire harness when carrying out extensive repairs.

    → If individual lines are damaged, shut off these lines and install new lines. Lay the new lines along the main wire harness and secure them to the main wire harness.
