Group 23 EDC III
Diagnostic function
NOTE:
If the warning lamps and other instruments
show normal function and the control is working nor-
mally, the operator can choose to continue operating
and remedy the disturbance later. If the engine is swit-
ched off, certain error codes could disappear.
Reading out error codes
If the diagnosis button
2
is depressed and then rele-
ased, an error code blinks out (
1
).
The error code consists of two groups of blinks sepa-
rated by a two-second pause. The error code is read
by counting the number of blinks in each group.
Example
:
pause
= Error code 2.4
The error code is stored and can be read as long as
the disturbance remains. The error code list contains
information on cause, response and corrective action.
Read out as follows:
1. Press in the diagnosis button (
2
)
2. Release the diagnosis button and note the error
code that blinks out (
1
).
3. Repeat points 1–2. A new error code blinks out if
more codes are stored. Repeat until the first error
code reappears.
NOTE:
When the first error code reappears all error
codes have been read out.
Erasing error codes
The error code memory of the diagnostic function is
reset when power to the engine is cut off.
NOTE:
The power must be completely disconnected.
When the power is turned on, the diagnostic function
checks to see if there are any disturbances in the
EDC III system. If disturbances are present, new error
codes are set.
This means that:
1. Error codes for disturbances that have been
corrected or that have disappeared are erased
automatically.
2. Error codes for disturbances that have not been
corrected must be acknowledged and read out
every time the power is turned on.
If the diagnosis button is pushed after the error has
been corrected and saved error codes are erased the
code 1.1 (”No errors”) will blink out.
