Note:
The multiple connector was eliminated as of approx. 12/93
Preparation for Test:
1. Pry off all pneumatic lines from pneumatic multiple connector (using
a 7 mm open end wrench.)
2. Plug all connections on the upper side of the pneumatic multiple connector
with plugs (part no. 124 805 02 44).
3. Connect vacuum/pressure tester to the bottom side of the pneumatic multiple
connector to test the individual connections ZV, SRU, OSL.
Parts Required for Test:
10 Plugs 124 805 02 44
1 Connector 129 805 04 44
Notes:
The connections on the PSE control module and pneumatic multiple connector
