4 Troubleshooting
5.2 ECU alarms
The ECU generates alarms which are indicated in different ways depending on the equipment configuration:
as four-digit code on a PIM
as alarm text on a display
as four-digit code on a dialog PC
The four-digit code consists of one letter and three figures:
The letter encodes when the fault occurred the last time:
A = currently present
B = within the last operating hour
C = one to four operating hours ago
D = four to twelve operating hours ago
Alarms that occurred more than twelve hours ago are deleted automatically.
The three figures encode the fault itself as listed in the table below.
Alarms can also be caused by defective sensors / actuators. If troubleshooting in accordance with the following
table is not successful, contact Service to have the sensors / actuators checked and, if required, replaced.
