 A. Test
 (1) Do the BITE test of the BMC1 (Ref. AMM TASK 36-11-00-740-001).
 4. Fault Isolation
_______________
 A. If the BITE test gives the maintenance message:
 BMC1 OR APU FAULT IND 7HV

 NOTE : If the maintenance message BMC1 OR APU FAULT IND 7HV comes into
____ view with no associated ECAM warning, no trouble shooting procedure is necessary.
 -Replace the BMC-1 (1HA1) (Ref. AMM TASK 36-11-34-000-001) and (Ref. AMM TASK 36-11-34-400-001).
 (1) If the fault continues:
 -Replace the P/BSW-AIR COND/APU BLEED (5HV) (Ref. ASM 36-12/01).
 (a) If the fault continues:
 -Do a check and repair the wiring (Ref. ASM 36-12/01) between: . Pin A/B1 of the APU bleed pushbutton switch (5HV) and pin AA/14C of the BMC1 (1HA1) . Pin A/B3 and the ground.
