Test values, control moduleconnections
| Test values, control module connections |
| Some important points to remember: |
| • |
Unless otherwise specified, all
voltage measurements should be made
with all components connected and with the ignition switch in the Drive
position.
|
|
| • |
Readings must be taken with a Breakout Box (BOB) connected between the
control module and the control module connector.
|
|
| • |
Some readings are to be taken with the engine running at idling
speed.
|
|
| • |
Several voltage levels must be regarded as guiding values. Your common
sense should tell you whether a reading is correct or not.
|
|
| • |
If any test reading is obviously wrong, use the wiring diagram to trace
the leads, connectors or components which you consider ought to be
checked more thoroughly.
> = greater than; < = less than; » = approximately equal to; ∼ = alternating current |
