Test Readings, Control Module Connections
Scope
Values and directions for measuring control module voltages can be found under the relevant heading.
Remember:
-
Note the test conditions and use common sense when assessing the test result.
-
The specified values are with the ignition ON unless otherwise stated.
-
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 values do not indicate whether the actuator unit 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 test readings given apply to a calibrated Fluke 88/97.
-
Test readings in %(+) and ms(+) show the pulse ratio and pulse duration of the signal. A test instrument capable of giving pulse ratio and pulse
duration readings must be used. The (+) sign indicates a positive trigger pulse, TRIG+.
