Control Module: Testing and Inspection
Test readings, control module connections
Scope
The following pages contain values and directions for measuring transmission control module signals and levels.
Points to remember
^
Observe the test conditions, use your common sense when judging the readings obtained.
^
The specified readings are with the ignition in position ON unless stated otherwise.
^
First check that the control module is supplied with current and grounded.
^
Then check all sensor inputs and signals from other systems.
^
Finally, check the control module outputs. Remember that the 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 which ought to be checked more thoroughly.
^
The specified test readings refer to those obtained with a calibrated Fluke 88/97.
^
All readings are with warm engine/gearbox.
^
Test readings %(+) and ms(+) indicate the signal's pulse ratio and pulse duration. A test instrument capable of measuring pulse ratio and pulse
width must be used. The sign denotes a positive trigger pulse, TRIG+.
