Note:
Lubricants and oils can contaminate the micro switches (F305) and lead to long-term damage. Do not apply lubricants such as silicon oil to the
gearshift housing, even if the gearshift housing appears to be stiff.
Measure the resistance of the switch F305 (required value in position P about 470 Ohm).
Replace F305 if out of spec being careful not to break the tabs on the housing.
