Test Readings, Control Module Connections

Scope
The following pages contain readings and instructions for measuring signals and levels on the Trionic control module.

Remember:
- Note the test conditions and use your common sense when judging the test results.
- 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 test readings do not indicate whether the actuator is in working order.





- If any reading is not OK, consult the wiring diagram to trace the leads, connectors or components that ought to be checked more thoroughly.
- The test readings given apply to a calibrated Fluke 88/97.
- The test readings % (+) and ms (+) show the signal's pulse ratio and pulse duration. A test instrument capable of measuring pulse ratio and pulse duration must be used. The sign indicates a positive trigger pulse, TRIG+.
