Test Readings, Control Module Connections/ Trionic T7

Test Readings, Control Module Connections







Scope
The following pages include values and directions for measuring signals and levels on the main instrument unit and its control module.

Remember:
- Note the test conditions and use common sense when assessing the test result.
- The test readings presented 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 test readings do not indicate 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 58/97.
- 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+.

- 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+.
