Test Readings, Control Module Connections

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







Remember
- Note the test readings, use common sense when assessing the results of the tests.
- The specified values are with the ignition in the ON position unless otherwise stated.
- First, make sure the control module is supplied with power and grounded.
- Then, check all the 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 of the test readings is incorrect, use the wiring diagram to determine which lead, connector or component should be checked further.
- The specified test values apply for a Fluke 88/97.
- The test readings % (+) and ms (+) signify the pulse ratio and pulse length of the signal respectively. A test instrument capable of measuring pulse ratio and pulse width must be used. The sign indicates a positive trigger pulse, TRIG+.
