A. Test
(1) Do the operational test of the engine fire and overheat detection from the Multipurpose Control and Display Unit (MCDU) (Ref. AMM TASK 26-12-00-710-002).
4. Fault Isolation
_______________
A. If the test gives the maintenance message CHECK FDU ENG 1 LOOP B WARN CKT:
- replace the FDU-ENG1 (2WD1) (Ref. AMM TASK 26-12-34-000-001) and (Ref. AMM TASK 26-12-34-400-001).
(1) If the fault continues:
- do a check and repair the wiring of the INOP LOOP B discrete from the engine 1 FDU (2WD1) to the first terminal block (Ref. ASM 26-12/01).
B. Do the test given in Para. 3.
