Saab Information Display (SID): Testing and Inspection
Test Readings, Control Module Connections
Remember:
-
Unless otherwise stated, all voltage measurements should be carried out with all components connected and with the ignition switch in the Drive
position.
-
Readings should be taken with a Breakout box (BOB) connected between the Saab Information Display (SID) unit and its connector.
-
Several voltage levels should be regarded as guiding values. Use your common sense when judging whether a particular reading is correct or not.
-
If any reading is not OK, consult the wiring diagram to trace the leads, connectors or components which ought to be checked more thoroughly.
