Ignition Pos not defined The diagnostic value is made up of the fol-
lowing faults or their combinations (the in-
dividual diagnostic codes are added up in
hexadecimal format)
Ignition Pos not defined Ignition position of the air actuator
Ignition Pos not defined Ignition position of the active fuel actuator
has not been parameterized
Ignition Pos not defined Ignition position of auxiliary actuator 1 has
not been parameterized
Ignition Pos not defined Ignition position of auxiliary actuator 2 has
not been parameterized
Ignition Pos not defined Ignition position of VSD has not been pa-
rameterized
Ignition Pos not defined Ignition position of auxiliary actuator 3 has
not been parameterized
Running time fault of actuators / VSD.
Fault Running Time The diagnostic value is made up of the fol-
lowing faults or their combinations (the in-
dividual diagnostic codes are added up in
hexadecimal format)
Fault Running Time Air Actuator Running time fault of air actuator
Fault Running Time Aux Actuator Running time fault of auxiliary actuator 1
Fault Running Time Aux Actuator Running time fault of auxiliary actuator 2
Meaning for the LMV5x system Troubleshooting
Check the relevant actuators to see if they are mechanically
overloaded. Check power supply to the actuators and their
fuses.
The actuator's ramp must be smaller to or equal to the
ramp parameterized in the basic unit.
The parameterized ramp of the VSD must be smaller than
the ramp parameterized in the basic unit (recommendation:
20 %)
