Power Window Control Module: Testing and Inspection

Test Readings, Control Module Connections

Extent







The following are the values and instructions for obtaining readings of signals and levels on the control module.

Remember

- Note the test conditions and use your common sense when judging 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.
- Check the control module outputs last. Remember that the test readings do not indicate whether or not the actuator is working.
- 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 correctly calibrated Fluke 88/97.
- The readings indicate the pulse ratio and pulse duration of the signal. A test instrument capable of measuring both pulse ratio and pulse duration must be used. The + sign denotes a positive trigger pulse (TRIG+).
