1. Remove harness 12349810 plug (1) from harness 12349813 jack
(2) at carrier bulkhead.
2. Measure voltage between each socket on harness 12349813 jack
(2) and ground. Multimeter should read 0 volts for sockets B (3),
D (4), and H (5), and at least 18 volts for the remaining socket
checks.
3. Does multimeter read more than 0 volts at sockets B (3), D (4),
and H (5), or less than 18 volts at all remaining sockets?
YES
NO
YN
1. Faulty harness 12349810
(transmission control wiring
harness). Beyond unit maintenance
repair.
2. Notify supervisor.
2Y

3. Remove transmission controller (WP 0386 00 or WP 0387 00).
4. Measure resistance between transmission controller jack (1) pin
M (2), and pins A thru G. Multimeter should read infinity for pins
B and D, and read 0 ohms for pins A, C, E, F, and G.
5. Does multimeter read less than infinity for pins B and D, or more
than 0 ohms for pins A, C, E, and G?
