Test readings, control module connections







Scope
Readings and directions for measuring control module voltage levels can be found under this heading.

Remember:
- Note the test conditions and use common sense when assessing the test result.
- The specified readings are with the ignition in position 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 readings do not determine 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.
- 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+.
