are:
There is an open circuit or a poor wiring harness connection.
There is a switch in OPEN position.

possible causes of an FMI 06 diagnostic code are:
There is a short to ground in wiring harness connection.
There is a shorted relay.
A faulty control will also cause an FM 06, although this is very unlikely.

correct. Some possible causes of an FMI 07 diagnostic code are:
Properly.
Component responds improperly.
Component is stuck in a position.
Component has failed.
Engine is shut down.
Machine is being used improperly.
08
This code occurs when signal is not in expected range. FMI 08 can also relate

to a faulty sensor. Some possible causes of an FMI 08 diagnostic code are:
Period.
Wiring harness connectionsare intermittent or poor.
Engine misfired.
There are loose mechanical devices.
09
Abnormal Update.
This relates to communications on data link. FMI 09 occurs when a control is
not able to get information from another control. Some possible causes of an
FMI 09 diagnostic code are:
Control module is not communicating on data link correctly.
Rate of data transmission is abnormal.
Data link has failed.
There is a mismatch of software.
