Pinout Values and Diagnostic Parameters

TEST READINGS, CONTROL MODULE CONNECTIONS

Points To Remember:
- Readings should be taken via a 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 an instrument reading is correct or not.
- If any reading is incorrect, use the appropriate wiring diagram to ascertain which leads, connectors or components ought to be checked more closely.
- The references in the table relate to the principle of operation of the component concerned and to the relevant fault diagnosis schedule containing a detailed description of the diagnostic procedure to be followed.
- All test readings are in respect of a warmed-up engine.
- Unless otherwise specified, the ignition should be switched on.
- Indicated readings refer to calibrated FLUKE 88/97.
