WARNING
Wear appropriate eye protection when
working under vehicle due to the possibility
of falling debris. Failure to comply may
result in injury to personnel.
CAUTION
Loose or dirty connectors may cause
intermittent loss of power to transmission
ECU and diagnostic codes to be logged.
Ensure that all connectors are clean and tight
before performing troubleshooting. Failure to
comply may result in incorrect test results.

NOTE
Inspect connector pins/sockets for damage,
corrosion, and serviceability. Check that
connector pins are not pushed back and
are capable of making good contact.
RESISTANCE TEST
(1) Disconnect output speed sensor connector
from transfer case connector.
(2) Set multimeter to ohms.
(3) Connect positive (+) probe of multimeter to
pin C of transfer case connector.
NOTE
A good output speed sensor will return a
reading of 200-400 ohms resistance as
follows:
a. 200 ohms at -40 F (-40 C)
b. 300 ohms at 68 F (20 C)
c. 400 ohms at 230 F (110 C)
(4) Connect negative (-) probe of multimeter to
pin D of transfer case connector and note
reading on multimeter.
(5) If good resistance is not noted, notify DS
Maintenance.
(6) Connect output speed sensor connector to
transfer case connector.
