Test Readings, Control Module Connections
Scope
The following contain readings and directions for measuring signals/levels on the Trionic control module.
Keep in mind:
-
Note the measuring conditions, use common sense when considering the measurement results.
-
The specified values are with the ignition in the ON position unless otherwise stated.
-
First, check that the control module is supplied with power and that it is grounded.
-
Then check all the 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 measured value is incorrect, use the wiring diagram to diagnose which leads, connections or components that should be checked further.
-
Specified values refer to calibrated Fluke 88/97.
-
The measured values %(+) and ms(+) indicate the pulse ratio and pulse length of the signal respectively. A test instrument with pulse ratio
respective pulse width measuring capacity must be used. The sign indicates positive trigger pulse, TRIG+.
