This is strange.
The 350 trucks from 2005 have the new modules (part No starting from 390), similar to the ones used on 391 series.
The Pathfinder with the cables 3903820101 (canbox - truck connection) and 3903820100 (canbox - computer connection) should work properly.
Make sure, if the Linde guy with the computer has the actual base in Pathfinder for such trucks.
Once we enountered such problem with communication and the problem was in the test cables loom on the truck. For several years nobody used them and they got rusted, the insulation was in lousy condition too.
Check this. Perhaps it'll help.
