1.2.42
Text-module
Failure location (MAN):
42
Text-module
Failure display:
Message on Dashpanel
Text-module
Failure path:
Injection Pump (Control Module) Fuel Temperature to high or Temperature sensor failure.
Text-module
Consequences:
If values are not plausible, system will switch to substitution Value (75
°
C) . Fuel Flow will be reduced
according to Speed.
Text-module
Possible Origin:
Fuel Temperature to high , Injection Pump Failure
Text-module
Remark:
Before Replacing any Pump or Control Module, failure Codes must l be analyzed and then deleted.
In case of several Failure Codes, check first the Test procedures wich are not requesting a replacement
of the Control Module or of the pump.

- Record Failure and ambient Para-
meters with FENDIAS
Check with FENDIAS wether Values are
out of thresholds but realistic (e.g. Tem-
peratur by cold Engine).
- Delete Failure Code Memory with
FENDIAS
- Check again with FENDIAS, let fuel
cool down
- If Failure Persists, Replace Injection
Pump
