4. Check for short to +battery circuit.
(a) Battery disconnect switch remains in
OFF position (TM 5-3805-291-10).
(b) All related ECMs remain disconnected
from wiring harness.
(c) At wiring harness connector for
powertrain ECM, perform these
checks:
(1) Measure the resistance between con-
tact J1-31 (wire 170-RD) and con-
tact J1-20 (wire 945-BR).
(2) Measure resistance between contact 1. If resistance is greater than 5,000 Ohms,

5. Check for open circuit in harness.
(a) Battery disconnect switch remains in
OFF position (TM 5-3805-291-10).
(b) All related ECMs remain disconnected
from wiring harness.
(c) Measure resistance of CAT Data Link
circuit in wiring harness:
(1) Measure resistance from contact J1-
20 (wire 945-BR) of harness con-
nector for powertrain ECM to con-
tact 5 of harness connector for
Messenger.
