This contains readings and instructions for measuring voltage levels on the SID unit.
Remember
-
Note the test conditions, and use common sense when assessing the test results.
-
First check that the control module is supplied with current and grounded.
-
Then check all sensor inputs and signals from other systems.
-
Finally, check the control module outputs. Remember that the test readings do not indicate whether or not the actuator is in working order.
-
If any reading is not OK, consult the wiring diagram to trace the leads, connectors or components which ought to be checked more thoroughly.
-
The test readings given apply to a calibrated Fluke 88/97.
-
The test readings show the signal's pulse ratio and pulse width. A test instrument with pulse ratio and pulse width measurement must be used. The
sign indicates a positive trigger pulse, TRIG+.
