Diagnostic function
48
NOTE! If the warning display and the instrumentation
indicates normal function. The operator can choose to
continue operation and take corrective actions later
on. If the engine is shut down certain error codes can
disappear
Reading out error codes
If the diagnosis button (2) is pushed and then released
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 saved and can be read out as long
as the disturbance is present. The error code list con-
tains information on causes, responses and measures
to be taken.
Read out as follows:
1. Push the diagnosis button (2).
2. Release the diagnosis button and note the error
code that blinks out (1).
3. Repeat points above. 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 diagnosis function’s error code memory is reseted
every time the engine power is turned 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
EDCIII 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.
