Test Readings, Control Module Connections: Remember
WARNING: This page is about a different car, the 2006 Saab 9-5. However, it is still accessible from the selected car via links, so may be relevant.
- Note the test conditions and use common sense when assessing the test result.
- The nominal values specified apply with the ignition in the ON position unless otherwise stated.
- First check that the control module has a power supply and is grounded.
- Then check all sensor inputs and signals from other systems.
- Finally, check the outputs. Remember that the test results do not tell us whether or not the module is functioning properly.
- If any reading is not OK, consult the wiring diagram to trace the leads, connectors or components which should be checked more thoroughly.
- The specified test readings refer to those obtained with a calibrated Fluke 88/97.
- Test readings in % (+) and ms (+) show the pulse ratio and pulse duration of the signal. A test instrument capable of giving pulse ratio and pulse width readings must be used. The sign indicates a positive trigger pulse, TRIG+.
