The faults may be enabled but the fault type might be set to no reporting, you can change the fault type to No report or as I copied/pasted below. There are 2 separate tables in powrtuner. Fault enable and fault type. Below is the fault type table.
0 = 1 trip SES on, 3 trips SES Off. 1 = 2 trips SES On, 3 trips SES off. 2 = Service On. 3 = No Reporting.
