Test Preparation

The vacuum test is subdivided into 5 test Circuits (A to E) If there is a certain fault (eg, footwell flaps fail to open), the corresponding circuit can be tested first.

If a leak is suspected in the total vacuum system for automatic climate control, first perform test step "A" and then proceed through the test circuits one after the other until the faulty vacuum Circuit is localized.
