Note on the replacement of the steering angle sensor - vehicles before mod. 03: Notes

A new steering angle sensor -C2-  will be installed from the 2003 model onwards (3 programmes). This intrinsically modified steering angle sensor -C2-  differs (externally) from the previous steering angle sensor -C1-  by its larger plug connection which is positioned differently. New steering angle sensor -C2-  : axial plug connection (underneath steering shaft) / previous steering angle sensor -C1-  : radial (lateral) plug connection.

• In the case of replacements, the new steering angle sensor -C2-  can be installed retroactively in place of the previous model -C1-  .

• When installing the new steering angle sensor -C2-  for the first time in vehicles prior to the 2003 model, a new cable guide -B2-  must be installed (in place of the old one) together with an adapter lead -E-  because of the modified plug connection (larger connector, connector position and modified connector assignment). See Fig 2 .

• The main difference between the old cable guide -B1-  and the new one -B2-  (series installation after 2003 model) is the cable deflection on its end. Refer to Fig 3 . The cable shaft (ribs) of the new cable guide -B2-  are interrupted in places to install the guide (ribs in old cable guide -B1-  are not interrupted).

• The adapter lead -E-  is installed (assembled) between the new steering angle sensor -C2-  and the available (previous) lead -X-  . Refer to Fig 4 . The connected leads -X and E-  are then installed with the plug connection in the cable shaft of the new cable guide -B2-  and fixed with the tie-wrap -arrow-  .
