Test readings, control module connections: Notes

WARNING: This page is about a different car, the 2005 Saab 9-3. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Testing using a test instrument must not be carried out on the ignition circuit with components connected. The components must be disconnected and a reference resistance connected before testing is carried out. Values can be read from the ignition circuit with components connected when using the diagnostic tool. The values stated for the diagnostic tool show within which interval the resistance should be with a correct circuit.

NOTE: All units on the I and P buses send signals.
