_______________
 A. Do this trouble shooting procedure
 NOTE : You can find the DPI extended with CFDS fault messages.
____ First, do the trouble shooting for each CFDS fault messages. For this, refer to the CFDS index list.
 (1) If no message is found:
 - replace the IDG (4000XU) (Ref. AMM TASK 24-21-51-000-040) and (Ref.
 AMM TASK 24-21-51-400-040), - or do the alternate procedure (IDG DPI reset).

 . For normal operations: weekly or 100 FH (the one that comes
 first).
 . For Extended Range Twin-Engined Aircraft Operations (ETOPS):
 before each flight.
 If, after a DPI reset, the DPI does not extend again between two
 scheduled oil/filter changes, you can cancel the conditions
 related to this procedure:

 - The DPI reset status goes back to zero (a maximum of three more resets is permitted).

 - The DPI check interval goes back to the interval specified in the MPD. (Ref. TSM 24-21-00 P.Block 301)


 (1) If this is the first reset:
 (a) Do a check of the IDG2 oil filter(s) and the cover(s) for metal particles (Ref. AMM TASK 24-21-00-210-044):
 1 If you find metal particles:
_
 - replace the IDG (4000XU) (Ref. AMM TASK 24-21-51-000-040) and (Ref. AMM TASK 24-21-51-400-040).
 2 If yo do not find metal particles:
_ a Drain the oil, replace the oil filter(s) and fill the IDG2
_ with oil (Ref. AMM TASK 24-21-00-920-040).
 b Do a reset the DPI.
_
 c Use a sticker, tag or other method to write on the IDG that
_ you did the first reset of the DPI.
 (2) If this is not the first reset:
 (a) Do a check of the number of reset:
 - if you did three resets: . replace the IDG (4000XU) (Ref. AMM TASK 24-21-51-000-040) and (Ref. AMM TASK 24-21-51-400-040).

 - if you did less than three resets done: . do a check of the IDG2 oil filter(s) and the cover(s) for metal particles (Ref. AMM TASK 24-21-00-210-044).
