Test conditions:
Battery min. 11.3 V
Potentiometer calibration --> window 8
NOTE: If no calibration is possible, there may be a problem with the pedal mechanism in addition to
a defective potentiometer.
Error number
19 Not calibrated
A new LHC control module was installed in the vehicle so that the reference value of the
potentiometer must be transmitted to the module. --> window 8 (calibration)
NOTE: If the LHC module is not supplied with electric power for several hours, error code 19 can
appear --> window 8 ( calibration)
Truck responses: W – E – L – F – S
20 Invalid truck encoding
No truck type detected.
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
21 Invalid engine type encoding
The wrong engine type was identified (e. g. LPG instead of diesel engine)
Possible cause could be a faulty cable loom. Check by measuring the inputs and outputs on the
LHC module.
Truck responses: W – E – L – F - S
22 Invalid series encoding
A wrong series was identified (e. g. 351 instead of 350)
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
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
