Pneumatic Test Program - Preparation for Test
Preparation for Test:
1. Fuses for PSE system and PSE control module ok,
2. Battery voltage 11 - 14 V.
3. Unlock vehicle using IR transmitter.
4. Connect reservoir with vacuum Y-distributor to vacuum/pressure tester.
6. Provide access to PSE control module (A37) and disconnect PSE pneumatic
multiple connector (do not disconnect wiring harness).
7. Connect vacuum/pressure tester with reservoir to PSE control module
(see  32, Figure 1).
Parts Required for Test:
1 Reservoir 107 800 08 19
1 Y-distributor 117 078 01 45
3 Plug 210 800 00 53
1 Connection hose, 50 mm long 007 997 61 82
2 Pneumatic line, 1 m long 000 158 14 35
Notes:
1. Before testing the safety switch time of the consumers, as well as between
the tests for OSB (pressure) and MVA (vacuum), interrupt the
PSE control module power supply for at least 3 seconds.
2. After completing the PSE control module test, do not operate any
system which would require vacuum or pressure for approx. 10 minutes.
3. The connections on the PSE control module are marked with their German
acronyms. Reference to these connections in this test are made to their
U. S. equivalents. In other words:
ZV (German) = CL (U.S.),
SRU (German) = MVA (U.S.),
OSL (German) = OSB (U.S.). |
