Preliminary Work For Occupant Detection Control Unit

Information 

If occupant detection components (installed for country equipment USA/Canada/Mexico) must be replaced, the repair kit comprising padding, occupant detection control unit and pressure sensor mat Must  always Be Replaced As A Complete Unit  .

The spare parts are grouped in a repair kit (comprising padding -1-, occupant detection control unit -2- and pressure sensor mat -3-), which must always be replaced as a complete unit.

A Mixed Installation  , e.g. "old" pressure sensor mat and "new" control unit, is Not Permitted  .

The padding, pressure sensor mat and occupant detection control unit are calibrated together by the manufacturer and must therefore only be replaced as a complete unit.

The occupant detection control unit does Not  have to be coded.

Information 

The connector of the occupant detection control unit must be inserted straight as otherwise the seal will be damaged. The seating of the seal must then be checked.
