(6) Do a check of the resistance and insulation of the LVDT/RVDT of the unit C.

 (a) If the check is correct:

 - connect the electrical connector to the unit C

 - continue, the trouble shooting.

 (b) If the check is not correct:

 - replace the unit C or the LVDT/RVDT

 - connect the electrical connector to the unit C

 - refer to the procedure that you did before.
