Preparation For Test

Preliminary Work:
- Perform ETP - Electrical Test Program ETP - Electrical Test Program

Data (mbar):
Test Procedure Permissible deviation:
Permissible leakage from the entire system at > 2 bar
pressure in 1 minute Max. 100 mbar

Preparation for Test:
1. Provide access to closing assist supply pump (M143).
2. Assemble test lines according to connection diagram ([ ] 33. Figures).
3. Connect test lines and pressure gauge according to connection diagram ([ ] 33, Figure 1 or 2).

NOTE: If one or more pneumatic circuits of the CA supply pump are switched off by the safety feature (incorrect pressure buildup times), the pump can be reset by briefly interrupting circuit 30. This can be done by removing fuse F4-9 in rear fuse box F4 for approx. 5 seconds or by disconnecting the connector from the CA supply pump (M14/3).





Special Tools

NOTE: Any suitable pressure gauge which reads in bar (range 1 to 5 bar) can also be used.
