(a) If the test gives a different maintenance message, you can find the related trouble shooting procedure in the applicable Page Block 101.
(2) If the fault continues:
- do a check and if necessary repair the wiring between the FCU (2CA) and the DMU/FDIU (FDIMU) (10TV) (Ref. ASM 31-37/01):
FCU Connector A/DD to FDIMU Connector AA/5A FCU Connector A/EE to FDIMU Connector AA/5B FCU Connector A/FF to FDIMU Connector AB/5A FCU Connector A/GG to FDIMU Connector AB/5B
