Scope
The following information contain readings and instructions for measuring signals and levels on the head unit and its control module.
Remember:
- Note the test conditions and use common sense when assessing test results.
- 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 readings do not say anything about 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.
- Test readings %(+) and ms(+) 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+.
