Test Readings, Control Module Connections














Scope
Nominal values and instructions for measuring voltages on the module are specified below under the respective headings.

Remember
- Note the test conditions and use common sense when assessing the test result.
- The nominal values specified apply with the ignition in the ON position unless otherwise stated.
- 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 outputs. Remember that the test results do not tell us whether or not the module is functioning properly.
- If any reading is not OK, consult the wiring diagram to trace the leads, connectors or components which should be checked more thoroughly.
- The specified test readings refer to those obtained with a calibrated Fluke 88/97.
- Test readings in % (+) and ms (+) show the pulse ratio and pulse duration of the signal. A test instrument capable of giving pulse ratio and pulse width readings must be used. The sign indicates a positive trigger pulse, TRIG+.







>= greater than; <= less than; - = approx. equal to; = AC voltage (LP: LOGIC PROBE P = select pulse; p = visible pulses)
