Test readings, control module connections, main instrument unit: Remember

Note the test conditions 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 these readings are not an indication that the actuator is in working order.
If a 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 are based on the use of a calibrated Fluke 88/97.
Readings %(+) and ms(+) indicate the signal pulse ratio and pulse width respectively. A test instrument with pulse ratio and pulse width measurement must be used. The sign (+) indicates a positive trigger pulse, TRIG+.
