4. Fault Isolation
_______________
A. If the fault symptom is identified by the CFDS message IDG 2 LOW OIL PRESSURE and the upper ECAM DU warning IDG 2 OIL LO PR:
NOTE : You can find this message with other CFDS fault messages. Do this
____
trouble shooting procedure first.
- do a check of the IDG2 oil level (Ref. AMM TASK 24-21-00-210-046).
(1) If the oil level is low:
- do a visual inspection of the IDG2 and external system (tubings, cooler) for oil leaks (Ref. AMM TASK 24-21-00-210-047).
(a) If you find no leak:
- add oil (Ref. AMM TASK 12-13-24-612-041).
(2) If the oil level is correct:
- do a check of the Differential Pressure Indicator (DPI) of the IDG2 (Ref. AMM TASK 24-21-00-210-046).
(a) If the DPI is extended:
- do the alternate procedure (Ref. TASK 24-21-00-810-816).
(b) If the DPI is not extended:
- do an inspection of the IDG2 filter element (Ref. AMM TASK 24-21-00-210-044).
