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.
Use care when testing electrical connectors.
Do not damage connector pins or sockets
with multimeter probes. Failure to comply
may result in damage to equipment.
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 -40F (-40C)
b. 300 ohms at 68F (20C)
c. 400 ohms at 230F (110C)
(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.
