67 Lift and tilt signals incompatible (14 bar before 6 bar)
The normal switching sequence, first 1S1 then 1S2, is out of sequence.
Possible causes: connectors of both pressure switches 1S1 and 1S2 are interchanged, pressure
switch 1S1 defective, cable loom from pressure switch 1S1 has an open connection.
Truck responses: W
70 - 79 Mutual monitoring of both processors
The internal communication between the master and the safety processor is faulty.
Possible cause: LHC-module 1N2 defective
Truck responses: W – E – L – F – S
80 - 99 Safety processor error messages
The safety processor is detecting errors in LHC module 1N2.
Possible cause: LHC module 1N2 defective
Truck responses: W – E – L – F – S
NOTE: If there is a single error code between 70 - 99, the LHC module can be assumed to be defective.
If further codes under 70 are detected, these must be considered first.
NOTE: If there is no diagnostic output of module LHC 1N2 and/or the vehicle can not be started, and/
or the warning lamp is not on, LHC module 1N2 can be assumed to be defective if the following
conditions are fulfilled:
- Fuse 1F17 and 1F18 are OK
- Power supply, positive and negative signals present
- Diagnostic cable (communications to the test module/ laptop) is OK
