802. ISDU FAIL -Fault Isolation
A. Description
(1)
This task is for this maintenance message:
(a) 34-21001 ISDU FAIL
(2)
The maintenance message is identical for the left and right air data inertial reference systems ADIRS. The left ADIRS maintenance message is shown on the ADIRS L BITE page on the control display unit (CDU). The right ADIRS maintenance message is shown on the ADIRS R BITE page on the CDU.
(3)
The inertial system display unit (ISDU) supplies both ADIRUs with test discrete and present position data. The ADIRUs supply IR data, ADR data, and fault data to the ISDU.
(4)
This message shows when the inertial system display unit (ISDU) fails to provide data to the ADIRUs.
B. Possible Causes
(1)
Wiring between the ISDU and the ADIRU
(2)
ISDU P5-70
(3)
ADIRU, M1749 (left) or M1752 (right)
C. Circuit Breakers
(1) These are the primary circuit breakers related to the fault:
