Body Control Module: Specifications
Test Readings, BCM
Scope
The following information contain values and instructions for measuring signals and levels on BCM.
Remember:
^
Note the test conditions and use common sense when assessing the test results.
^
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 reading does not indicate whether the actuator works.
^
If any reading is not OK, consult the wiring diagram to trace which leads, connectors or components should be checked more thoroughly.
^
The specified values refer to a calibrated Fluke 88/97.
^
Test readings % (+) and ms (+) show the signal's pulse ratio and pulse length, respectively. A test instrument that can measure pulse ratio and
pulse width must be used. The sign indicates the positive trigger pulse, TRIG+.
