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.
- The presented readings are with the ignition ON 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 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 should be checked more thoroughly.
- The specified test readings refer to those obtained with a calibrated Fluke 88/97.
- The test values %(+) and ms(+) indicate the pulse ratio and pulse duration of the signal. A test instrument for measuring pulse ratio and pulse duration must be used. The (+) sign indicates a positive trigger pulse, TRIG+.
