R condition 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 (a) If there is no continuity:
R - repair or replace as necessary.

R (b) If there is continuity:
R - replace the GCU-2 (1XU2) (Ref. AMM TASK 24-22-34-000-001) and
