Test Readings, Control Module Connections

Test Readings, Control Module Connections







Scope
Values and instructions for testing the voltage levels of the control modules are found under the relevant systems.







Remember
- Note the test conditions and use common sense when assessing the test result.
- The test values presented apply when the ignition is 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 control module outputs. Remember that the test values do not indicate whether the actuator is working.
- 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 values in % (+) and ms (+) show the pulse ratio and pulse duration of the signal. A test instrument capable of giving pulse ratio and pulse duration readings should be used. The (+) symbol indicates a positive trigger pulse, TRIG+.
