2Y
1. Remove wiring harness 12313482 plug (1) from wiring harness
12313483 jack (2) at carrier bulkhead.
2. Measure voltage between each socket on wiring harness
12313483 jack (2) and ground. Multimeter should read 18 volts
or more for sockets B (3), D (4), and E (5) and 0 volts for the
remaining socket checks.
3. Does multimeter read less than 18 volts for sockets B, D, and E
and doesn’t read 0 volts for all other sockets?
YES
NO
2YN
1. Replace faulty wiring harness
12313482 (transmission control
wiring harness) (WP 0297 00).
2. Verify no faults found.

3. Remove transmission shift control (WP 0306 00).
4. Place transmission shift control in SL position.
5. Measure resistance between transmission shift control jack (1)
pin M (2) and pins A thru N. Multimeter should read 0 ohms for
pins B, D, E, and N and infinity for all remaining pin checks. See
pin to pin check (WP 0309 00).
6. Does multimeter read more than 0 ohms for sockets B, D, E, and
N and doesn’t read infinity for all other pins?
