Engine Control Module: Testing and Inspection
General
Scope
Test readings and instructions for measuring signals and signal levels on the Trionic control module are given in the following information.
Remember:
^
Readings should be taken via the Breakout box (BOB) connected between the control module and the control module connector.
^
Several voltage levels must be regarded as guiding values. Use your common sense when judging whether a reading is correct or not.
^
If any reading is incorrect, use the wiring diagram to ascertain which conductor, connector or component requires further testing.
^
The article references at "Function" in the charts refer to a description of operation of the relevant signal and partly to the fault diagnosis
schedule with a complete description of the diagnostic procedure to be followed.
^
All test readings are for an engine at normal operating temperature.
^
Unless otherwise stated, the ignition should be switched on.
^
The test readings in the table refer to a calibrated FLUKE 88/97.
