Test readings, control module connections



Scope

The following pages contain values and instructions for measuring signals and levels on the ECD U2P 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 are 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+.




>= greater than; <= less than; » = approximately equal to; ∼= alternating current

Pins without further comments have no connection. (LP: LOGIC PROBE P = select pulse; p = visible pulses).
