R A. If the Class 3 Faults gives the maintenance message IDG2 (E2-4000XU) OIL R OUT TEMP/ GCU2 (1XU2):
R NOTE : This CFDS message can come into view when the temperature of the
____ R IDG 2 oil is more than 151 deg.C but less than 185 deg.C. R If this CFDS message comes into view with other chapter-24 CFDS R messages, do the trouble shooting for all these messages. R If there is no other message, do the trouble shooting that R follows:
R (1) Do the trouble shooting for chapter-73 CFDS messages that come into
R view with the CFDS message IDG2 (E2-4000XU) OIL OUT TEMP/ GCU2
R (1XU2).
R (2) If there is no chapter-73 CFDS message or if the fault continues
R after the trouble shooting:
R - do the check of the Differential Pressure Indicator (DPI) of the
R IDG 2 (Ref. AMM TASK 24-21-00-210-046).
R (a) If the DPI is extended:
R - replace the engine 2 IDG (4000XU) (Ref. AMM TASK 24-21-51-000-R 040) and (Ref. AMM TASK 24-21-51-400-040).
R (b) If the DPI is not extended:
R - do a check of the IDG 2 oil level (Ref. AMM TASK 24-21-00-210-R 046).
R 1_ If the oil level is not correct:
R - replace the IDG 2 charge and scavenge filters (Ref. AMM TASK
R 24-21-00-920-040)
R - add oil (Ref. AMM TASK 12-13-24-612-041).
R 2_ If the oil level is correct:
R - do a check of the resistance of the oil inlet and outlet
R temperature-sensors of the IDG 2 (Ref. ASM 24-21/01)
R between:
R . pins B/7 and B/8 (100 ohms plus or minus 10 ohms at the R ambient temperature of the IDG case)
R . pins B/8 and B/9 (100 ohms plus or minus 10 ohms at the R ambient temperature of the IDG case).
R a_ If the resistance values are out of the specified limits:
R - replace the engine 2 IDG (4000XU) (Ref. AMM TASK 24-21-R 51-000-040) and (Ref. AMM TASK 24-21-51-400-040).
R b_ If the resistance values are in the specified limits:
R - do a check of the wiring of the oil outlet
R temperature-sensor (Ref. ASM 24-21/01) for an open
R circuit or a short to ground between:
R . pin B/7 of the IDG 2 and pin A/9C of the GCU 2
R . pin B/8 of the IDG 2 and pin A/9D of the GCU 2
R . pin B/9 of the IDG 2 and pin A/10C of the GCU 2.

R * If the wiring is not correct:
R - repair or replace as necessary.
R * If the wiring is correct:
R - replace the GCU-2 (1XU2) (Ref. AMM TASK 24-22-34-000-
R 001) and (Ref. AMM TASK 24-22-34-400-001).
R ** If the fault continues:
R - replace the engine 2 IDG (4000XU) (Ref. AMM TASK 24-21-
R 51-000-040) and (Ref. AMM TASK 24-21-51-400-040).
R B. When you replace a component or repair the wiring:
R - do the subsequent flight before you do the check of the Class 3 Faults
R of the GAPCU from the CFDS.
R If the test continues to give the fault message, continue the trouble
R shooting procedure.
