23 Invalid series / special version encoding
A wrong version was identified (e. g. instead of special version - fixed programmed speed
reduction, a series version)
Possible cause could be a defective cable loom. Check by measuring the inputs and outputs on
the LHC module.
Truck responses: W – E – L – F – S
26 Pressure sensor signal too high, and in particular over 9.5 V
The return voltage signal of pressure sensor 1B10 is over 9.5 V.
--> window 61
Possible causes: defective pressure sensor, shorted cable loom to and from sensor
Truck responses: W
27 Pressure switch and pressure sensor signals are both active
The switch and sensor signal at pressure sensor 1B10 are applied simultaneously.
Possible cause: defective pressure sensor
Truck responses: W
28 Pressure switch active although engine speed is zero
A switch signal 1B10 is applied although IC engine was not started and therefore no RPM are
indicated. --> window 6
Possible cause: pressure sensor defective, cable loom
Truck responses: W
31 The voltage values of potentiometers 1B2.1 and 1B2.2 do not match, and neither is 0 V.
The values supplied by both potentiometers are not within the admissible tolerance range.
Possible cause: potentiometer
32 The voltage value of potentiometer 1B2.1 is either too low or too high.
The voltage value supplied by potentiometer 1B2.1 is not within the admissible range. It is either
below 0.8 V or over 9.2 V. Check this value in window 6. For a setting of the maximum values see
the description in window 6. If an adjustment can not be carried out successfully, the potentiometer
could be defective.
Truck responses: W – B – L
33 The voltage value of potentiometer 1B2.2 is either too low or too high.
The voltage value supplied by potentiometer 1B2.2 is not within the admissible range.
Possible cause: potentiometer
Truck responses: W – B – L
34 Both potentiometers 1B2.1 and 1B2.2 at 0 Volt
The voltage of approx. 10 Volt specified by the LHC box can not be processed further.
Possible causes: potentiometer not connected, potentiometer defective, cable loom
Truck responses: W – B – L
