Checking Position Of PASM Connector For Clearance

Information 

On vehicles with coil springs, the connector grommets or the PASM connector line can rub against the coil spring while driving and can be damaged as a result. To prevent this from happening, the clearance of the PASM connector must always be checked when the following prerequisites are met:

• PASM connector was connected/loosened on the spring strut. 
• The error message "PASM fault" appears in the instrument cluster. 

1. Prepare for the test.
   1. 1.1 Raise the vehicle (vehicle springs must be completely relieved).

   2. 1.2 Centre the steering wheel.
2. Check the distance between the PASM connector holder (long pin on U-shaped connector holder) and the coil spring mounting point -dimension X-  .

   Distance between PASM connector holder and coil spring mounting point

   Distance OK  > Length 66 mm  < x < > Length 69 mm 

   Distance not OK  x < > Length 66 mm  or x > > Length 69 mm 

3. Check clearance of connector grommet and PASM line with respect to the coil spring.

   Clearance of connector grommet and PASM line with respect to coil spring

   1. 3.1 Place M10 drill bit -1-  on at least 2 windings of the coil spring -2-  .

      Clearance OK  If the M10 drill bit -1- is - not  touching the connector grommet -3-  and PASM line.

      Clearance not OK  If the M10 drill bit -1-  is touching the connector grommet -3-  and PASM line -4-  .

4. Further steps must be carried out, depending on the results of the check (see table below).

   Distance of PASM connector holder	Clearance of connector grommet and PASM line	Action required
   OK	OK	No further action required.
   OK	Not  OK	Push PASM line up into the retaining clip. See  If the clearance of the connector grommet and PASM line See  is still not OK, the coil spring must be replaced. > 408537 - DISASSEMBLING AND ASSEMBLING FRONT SPRING STRUT
   Not  OK	OK	Bend back PASM connector holder
   Not  OK	Not  OK	Bend back PASM connector holder See  If the clearance of the connector grommet and PASM line See  is still not OK, push PASM line up into the retaining clip See  If the clearance of the connector grommet and PASM line See  is still not OK, the coil spring must be replaced. > 408537 - DISASSEMBLING AND ASSEMBLING FRONT SPRING STRUT

5. Push PASM line up into the retaining clip by dimension -Y-  > Length 12.5 mm +/- 2.5 mm  .
