GENERAL
This section provides general troubleshooting procedures which will fault isolate the defective component(s) of
the Line Replaceable Unit (LRU) down to the defective Shop Replaceable Unit (SRU) and maintenance
procedures that are common to multiple LRUs.
1–21.
INITIAL FAULT INDICATION
a.
An LRU failure is indicated when one of the following occurs:
(1)
The green indicator light (POWER) did not come on when power was applied to the LRU.
or
(2)
The red indicator light (BIT) came on when input power was applied to the LRU or during unit operation,
when BIT runs continuously.
b.
When an LRU failure has been detected, proceed to further troubleshoot the LRU by using Electronic Shop
Transportable AN/TSM–191(V)3.
Results from this fault isolation will indicate SRU component(s) requiring
replacement.
The LRU fault isolation procedure is presented in paragraph 1–22.
