Component Tests and General Diagnostics

Test Readings, Control Module Connections

The following pages contain instructions and readings for testing the control module.

Remember:
- Note the test condition, 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.
Finally, check the control module outputs. Remember that the test readings do not indicate whether the actuator is working.
- 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 readings show the signal pulse condition or pulse length. A test instrument with pulse rate or width measurement must be used.
