Test readings, control module connections


Test readings and instructions for measuring voltage levels on the main instrument unit and its control module are given below.

Remember:


Readings should be taken via a BreakOut Box (BOB) connected between the control module and its connector.

Several voltage levels should be regarded as guiding values. Use your common sense when judging whether a particular reading is correct or not.

If any reading is not OK, consult the wiring diagram to trace the leads, connectors or components which ought to be checked more thoroughly.

Pages referred to in the table contain a technical description of the signal in question.

All test readings should be taken with the engine warmed up to normal operating temperature.

Unless otherwise specified, the ignition should be switched on.

The test readings indicated are in respect of calibrated FLUKE 88/97.
