Test Readings

Scope
This section contains the 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+.
