0590 02 - Continued.
(a) Turn battery disconnect switch to
OFF position (TM 5-3805-291-10).
(b) Disconnect and inspect all wiring
harness connections related to CAT
sure connectors are clean and
tightly connected. Refer to
Electrical Connectors Inspection
(c) Check connectors for proper
(d) Check wires at connector.
(e) Check each wire for nicks or signs
of abrasion in insulation.
(f) Check for moisture at connector.
(g) Check connectors for dirty or
(h) Check each pin and socket of
wiring harness connectors.
(i) Reconnect all connectors.
1. If wiring harness connectors are tight and
free of corrosion, go to Test 3.
2. If wiring harness connectors are in need
of repair, replace wiring harness in
question (WP 0195 00 thru WP 0201 00).
3. Check for shorts to ground.
(a) Battery disconnect switch remains
in OFF position (TM 5-3805-291-
(b) Disconnect wiring harness from all
ECMs that use CAT Data Link (WP
0056 00, WP 0057 00, WP 0060 00,
and WP 0063 00).
(c) At wiring harness for implement
ECM, measure resistance between
harness circuit resistance is correct. Go
frame ground and connector
to Test 4.
