Test readings, control module connections
| Test readings, control module connections |
| Keep in mind |
| • |
Note the test conditions, and use common sense when assessing the test results.
|
|
| • |
The specified readings are with the ignition in position ON unless otherwise stated.
|
|
| • |
First, check that the control module is supplied with current 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 correct, consult the wiring diagram to trace the leads, connectors or components that should be checked more thoroughly.
|
|
| • |
The test readings given apply to a calibrated Fluke 88/97.
|
|
| • |
The test readings 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+.
|
|
> = greater than; < = less than; ~ = alternating current (LP: LOGIC PROBE P = select pulse; p = visible pulse)
