Test Readings, Control Module Connections: Remember

Note the test conditions, use common sense when assessing the test results.

First check that the control module is supplied with current and is grounded.

Then check all the 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 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 indicated are in respect of 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+.
