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 18 volts or more for
socket B (3), C (4), E (5), and J (6), and 0 volts for the remaining
socket checks.
3. Does multimeter read less than 18 volts at sockets B (3), C (4), E
(5), and J (6), or more than 0 volts at all remaining sockets?
YES
NO
YN
1. Faulty harness 12349810
(transmission control wiring
harness). Beyond unit maintenance

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 0 ohms for pins
B, C, and E, and read infinity for all remaining pins.
5. Does multimeter read more than 0 ohms for pins B, C, and E, or
less than infinity for all remaining pins?
