allows the operator to view the fault codes. The active fault
code is started after this switch turns "ON" "OFF," if during
the output of the fault code this switch turns "ON" "OFF"
again, the output of the current fault code is interrupted and
the next fault code is displayed. Each depression of the
diagnostic switch causes the output of a fault code. If a
fault code is displayed, contact your authorized dealer for
repair. To know the fault code information, refer to the
