(1) If the TROUBLE SHOOTING DATA page gives the maintenance message VACU GEN:

 - do a check of the electrical connections 37MG/A and 37MG/B.

 (2) If the electrical connections are correct:

 - replace the GENERATOR-VACUUM (37MG) (Ref. AMM TASK 38-31-64-000-001) and (Ref. AMM TASK 38-31-64-400-001).
R **ON A/C 001-049, 051-099, 101-105, 151-199, 201-299,
 C. Do the test as given in Para. 3.
 (1) make sure that the vacuum toilet system operates correctly (Ref. AMM TASK 38-31-00-710-009).

 (2) After the subsequent flight, make sure that the fault does not continue.

 3. Fault Confirmation
__________________
 A. Do the operational test of the vacuum toilet system (Ref. AMM TASK 38-31-00-710-009).
 B. Do the bite test (Ref. AMM TASK 38-31-00-740-001).
 4. Fault Isolation
_______________
 **ON A/C 151-199, 210-299,
 A. If the operational test is OK:
 - Refer to the trouble shooting data of the bite test.
 (Ref. Fig. 201/TASK 38-31-00-991-001)

 (1) If the TROUBLE SHOOTING DATA page gives the maintenance message LIQD LVL XMTR:

 - clean and fully dry the inside of the differential pressure vent line.

 (2) If the fault continues:

 - do a check of the electrical connections of the small connector 40MG/A.

 (3) If the electrical connections are OK:

 - replace the XMTR-LEVEL PHASE OFF (40MG), (Ref. AMM TASK 38-31-62-000-001) and (Ref. AMM TASK 38-31-62-400-001).

 B. If the test gives a different maintenance message, you can find the related trouble shooting procedure in the applicable Page Block 101.
 - Refer to the CFDS-TROUBLE SHOOTING DATA page.
 (Ref. Fig. 201/TASK 38-31-00-991-001)

 C. Test
 (1) Do the operational test of the vacuum toilet system and make sure it operates correctly (Ref. AMM TASK 38-31-00-710-009).

 (2) After the subsequent flight, make sure that the fault does not continue.
