SID Module-Lighting
Readings, Control Module Connections, Xenon Headlamps
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 result.
^ First check that the control module has a power supply and is grounded.
^ Then check all sensor inputs and signals from other systems.
^ Lastly, check the control module outputs. Remember, the test values do not say anything about whether or not the actuator is in working order.
^ If a reading is incorrect, 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.
^ 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+.
