Test readings, control module connections(MIU 2)
| Test readings, control module connections (MIU 2) |
| 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.
|
|
| • |
Specified test readings are in respect of calibrated FLUKE 88/97.
