R . If the oil pressure is correct: R - stop the trouble shooting.
R (3) If the fault continues:
R - do the BITE test of the GAPCU (Ref. AMM TASK 24-41-00-740-002).
R (a) If the BITE test gives the message TEST FAILED:
R - push the line key adjacent to the TEST FAILED message.
R 1_ If the maintenance message GCU1 (1XU1) comes into view:
R - replace the GCU-1 (1XU1) (Ref. AMM TASK 24-22-34-000-001)
R and (Ref. AMM TASK 24-22-34-400-001).

R (b) If the BITE test gives the message TEST PASSED:
R - do a check and repair the wiring of the IDG 1 disconnect
R circuit (Ref. ASM 24-21/01) for a short to 28VDC between:
R . pin B1 of the ELEC/IDG1 pushbutton switch (5XT) and pin B3 of R the relay (7XT)
R . pin B2 of the relay (7XT) and pin X1 of the IDG 1 DISC CTL R relay (3XT)
R . pin B1 of the IDG 1 DISC CTL relay and pin A/2J of the GCU 1. R - do a check and repair the contact of the P/BSW-ELEC/IDG 1 (5XT) R for correct operation between pin B1 and pin B3 (normally open) R (Ref. ASM 24-21/01).
R B. Do this operational test to make sure that the system operates correctly.
R (1) Aircraft Maintenance Configuration
R (a) Energize the aircraft electrical circuits
R (Ref. AMM TASK 24-41-00-861-002).
R (b) Do the EIS start procedure (Upper ECAM DU and lower ECAM DU only)
R (Ref. AMM TASK 31-60-00-860-001).
R (2) On the ELEC panel 35VU:
R - push, release and push again the GEN 1 pushbutton switch (3XU1).
R (3) Do the operational test of the GAPCU (Ref. AMM TASK 24-41-00-740-R 002).
R (4) Start the engine 1 (Ref. AMM TASK 71-00-00-710-003).
R (5) Do this test:
