In the ES2 indicated CAN warnings can lead to the disconnection of the engine by the
engine electronics.
In the display of the ES2 the fault 1 "engine fault” or fault 3 "CAT / Deutz engine fault" is
indicated.
The exact fault cause can be read about the ES2, page 4, point 12 "protocols", 12.2" CAN
faults" as a number SPN select.
e.g. SPN = 100 => Oil pressure
SPN = 107 => Air filter
SPN = 110 => Cooling water
To delete the faults in the engine control device go forward as follows:
1. Switch off the ES2 control.
2. Remove selected fault.
3. Make the engine electronics for approx. 20 sec. without tension.
4. Turn on the ES2 control . Wait after appearance of the basic display approx. 10 sec. Start
afterwards the engine.
