B. Test
(1) Open the circuit breakers 11WQ and 12WQ.
(a) After 60 seconds, close the circuit breakers 11WQ and 12WQ.
(b) After one more minute, start the subsequent test.
(2) Get access to the MCDU/SDCU menu page AMM 31-32-00-860-005.
(a) Push the line key adjacent to the <ON GROUND FAULTS indication.
(b) The MCDU shows the fault message. If there is no fault, the MCDU shows NO FAILURE.
4. Fault Isolation(1) Open the circuit breakers 11WQ and 12WQ.
(a) After 60 seconds, close the circuit breakers 11WQ and 12WQ.
(b) After one more minute, start the subsequent test.
(2) Get access to the MCDU/SDCU menu page AMM 31-32-00-860-005.
(a) Push the line key adjacent to the <ON GROUND FAULTS indication.
(b) The MCDU shows the fault message. If there is no fault, the MCDU shows NO FAILURE.

A. If the test gives a different maintenance message:
Subtask 26-17-00-810-079-A ** ON A/C NOT FOR ALL - Do the trouble shooting procedure related to the maintenance message.
B. If the test gives the maintenance message TEST OK, no other maintenance action is necessary.
Subtask 26-17-00-810-080-A ** ON A/C NOT FOR ALL C. If the test gives the maintenance message WRG:PIN PROG:
Subtask 26-17-00-810-081-A ** ON A/C NOT FOR ALL - Do a check and repair of the PIN PROGRAMMING at the pin B/8D of the SDCU (10WQ) ASM 261701.
- Replace the SDCU [10WQ] AMM 26-17-34-000-001 and AMM 26-17-34-400-001.
D. Do the test given in Para. 3.
5. Close-upSubtask 26-17-00-860-058-A ** ON A/C NOT FOR ALL
A. Put the aircraft back to its initial configuration.
