WARNING
Remove rings, wristwatches, neck chains, and any other jewelry before working
around vehicle.
Jewelry can catch on equipment and cause serious injury.
Jewelry
and tools may short across electrical circuits and cause damage to equipment or
severe burns or electrical shock to personnel.
NOTE
•
The THAAD communication harnesses have J1939 terminator resisters at the LHS cab
controller and input module Y connectors. The THAAD communication harnesses must
be disconnected from Y connectors as noted in Steps 17 through 23.
Failure to
disconnect THAAD communication harness from Y connectors will cause incorrect
results.
•
To locate the THAAD communication harness Y connector for the VIM No. 1, follow the
three-conductor harness back from the VIM No. 1, 40 pin connector terminals 21 and 22
to the communication harness Y connector.
Step 17.
Disconnect THAAD control valve harness VIM 1, 40 pin connector (WP 0089) and
THAAD communication harness connectors for VIM No. 1. Check for no continuity
between (+) J1939 and (-) J1939 wires at VIM No. 1, 40 pin connector, terminals 22
and 21.
If there is continuity, repair J1939 wires (TM 9-2320-325-14&P) or replace
THAAD control valve harness (WP 0088).
