Test Values and Control Module Connections For Popular
Scope
Values and instructions for testing the voltage levels of the control modules are found under the relevant headed sections.
Remember:
-
Observe the conditions set for testing and use common sense when assessing the results.
-
The test values presented apply when the ignition is in the ON position unless otherwise stated.
-
First make sure that the control module is receiving power and that it is grounded.
-
Then check all the sensor inputs and signals from other systems.
-
Finally, check the control module outputs. Remember that the test values do not indicate whether the module is working.
-
If a test value is incorrect, consult the wiring diagram to trace which leads, connectors and components should be checked more thoroughly.
-
The specified test values refer to those obtained with 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+.
