A. Test
(1) Open the circuit breakers 14WH, 15WH, 17WH and 18WH, wait for approx. 10 s and close again, wait for a minimum of 30 s before you start the test.
(2) Do the operational test of the cargo compartment smoke detection (Ref. AMM TASK 26-16-00-710-001).
4. Fault Isolation
_______________
A. If the test gives a different maintenance message:
- Do the trouble shooting procedure related to the maintenance message.
B. If the test gives the maintenance message SMK DET FWD LDCC (XWH) CONTAMINATION, (XWH = FIN of the related smoke detector):
- replace the FWD LDCC smoke-detector (Ref. AMM TASK 26-16-15-000-001) and (Ref. AMM TASK 26-16-15-400-001).
C. Do the test given in para. 3.

_______________
A. If the test gives a different maintenance message:
- Do the trouble shooting procedure related to the maintenance message.
B. If the test gives the maintenance message WRG: CAN BUS X / SMK DET FWD LDCC (XWH), (XWH = FIN of the related smoke detector):
- do a check and repair the wiring between the CIDS DIR 1 (101RH) and the FWD LDCC smoke detector XWH (Ref. ASM 26-16/02).
(1) If the fault continues: do a check and repair the wiring between the CIDS DIR 2 (102RH) and the FWD LDCC smoke detector XWH (Ref. ASM 26-16/02)
(2) If the fault continues:
- replace the FWD LDCC smoke detector XWH (Ref. AMM TASK 26-16-15-000-001) and (Ref. AMM TASK 26-16-15-400-001).
