 A. If the test gives no 'g' values.
 - make sure that the CB 9TU is closed,

 - do a check for 28 VDC at the LA (6TU) connectors A/A and A/B (Ref. ASM 31-33/01).

 (1) If there is 28 VDC:

 - replace the ACCELEROMETER-THREE AXIS (6TU) (Ref. AMM TASK 31-33-16-000-001) and (Ref. AMM TASK 31-33-16-400-001)

 (2) If there is no 28 VDC:

 - do a check and repair the wiring as necessary (Ref. ASM 31-33/01), between:
 CB 9TU and the LA (6TU) connector A/A,
 LA (6TU) connector A/C and SDAC 1 (1WV1), SDAC 2 (1WV2) connector 11/C
 LA (6TU) connector A/D and SDAC 1 (1WV1), SDAC 2 (1WV2) connector 11/D
