connections related to location codes
are clean and tightly seated. Refer to
Electrical Connectors Inspection (WP
(c) Check for proper mating of connector.
(d) Check all wires at connector.
(e) Check each wire for nicks. Check each
wire for signs of abrasion in insulation.
(f) Check for moisture at connector.
(g) Check for dirty corroded contacts.
(h) Check each pin and socket.
(i) Reconnect all connectors.
1. If wiring harness connectors are tightly
connected and wiring harness
connectors are free from corrosion, go
to Test 4.
2. If one or more wiring harness
connectors are in need of repair, replace
wiring harness in question (WP 0195 00
thru WP 0201 00).
4. Check for shorts to ground.
(a) Battery disconnect switch and engine
start switches remain in OFF position
(b) Disconnect wiring harness connector
from powertrain ECM (WP 0063 00).
(c) At wiring harness for powertrain ECM, 1. If resistance is greater than 5,000 Ohms
measure resistance between frame
at contacts J1-26 and J1-28, and
ground and pins for location code (for
resistance measures less than 5 Ohms at
Location Codes for Transmission
contact J1-27 and J1-32, go to Test 5.
ECM, Table 7, in this work package). 2. If one or more resistance measurements
is not correct, replace wiring harness in
question (WP 0195 00 thru WP 0201
5. Check for an open circuit in wiring harness.
(a) Battery disconnect switch remains in
OFF position (TM 5-3805-291-10).
(b) ECM remains disconnected from
