TEST OR INSPECTION
If wire 2740 cannot be identified at door switch, measure continuity across switch from
terminal wire 1609 (gray) to both black wire terminals. Continuity should be measured
between all terminals when switch is closed (door switch is not pressed).
Turn Service Drive Lights Off (TM 9-2320-347-10). Turn battery disconnect switch to
OFF position (WP 0007). Remove rear stowage compartment R-1 door switch
(WP 0385), do not disconnect wires. Check for continuity between door switch terminal
wire 1471 (black) and a known good ground when switch is closed (door switch is not
If there is continuity, go to Step 19.
Check for continuity across door switch between terminal wire 1471 (black) and
terminal wire 2740 (black).
If there is no continuity, replace door switch (WP 0385).
With a test lead set, check for continuity across main wire harness wire 2740 (black)
from passenger side body wire harness rear body wire harness connector, terminal E to
a known good ground.
If there is continuity, repair wire 2740 in rear body wire harness if
repairable (TM 9-2320-325-14&P), or replace rear body wire harness
If there is no continuity, repair wire 2740 in main wire harness if
repairable (TM 9-2320-325-14&P), or replace main wire harness
