DIAGNOSIS
Diagnostic function
The indicator lamp in the yellow Diagnostics button
on the EDC system control panel starts to flash if the
system receives abnormal signals or if there is a mal-
function in the EDC system.
Press the button* for at least one second in order to
read off the Diagnostic Trouble Code (DTC) and to
acknowledge the alarm. A DTC message is flashed
as a two-stage code.
If there are several diagnostic trouble codes (DTCs)
stored the next code is flashed when the button is
pushed again. When the first DTC is repeated, all the
codes have been read off.
Diagnostic trouble codes (DTCs) are stored until
erased. This should be done after the malfunction or
source of the DTC has been identified and repaired.
NOTE! If the On-board Diagnostics (OBD) system
has triggered an event (for example stopped the
engine) you must erase the DTC before the en-
gine can be restarted. Refer to Erasing Diagnostic
Trouble Codes (DTC) below.
* Note. When the engine is stopped the diagnostic trouble
code (DTC) is flashed only after the EDC system is activated.
To activate the EDC system turn the ignition key to position
“I” (operating position).
Safety system for drives with electronic shifting
If the drive actuator should malfunction it can still be
operated manually by disconnecting the actuator from
the unit and moving the actuator to the required posi-
tion for Forward, Reverse or Neutral. Check the actua-
tor fuse first.
