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
35 Travel direction signal encoding is not OK
The controller can not sense if it is a single-pedal or two-pedal vehicle.
Possible causes: encoding plug (near key switch); travel direction switch not connected or faulty,
cable loom (negative signals to LHC box not present, check)
--> Window 4)
Truck responses: W – B – L
36 Signal from travel direction switch
A signal expected from the travel direction switch can not be detected.
Possible causes: travel direction switch, cable loom (check negative signals coming from travel
direction switch to LHC box ) --> window 4
Truck responses: W – B – L
