Question 1
The AWD shift control system(above) permits a 2-3 lock-out under certain conditions. The
vehicle has no second or third gear during all conditions. What could cause this condition?
a) An open circuit at "W"
b) A short to ground at "X"
c) A high resistance fault at "Y"
d) A short to ground at "Z"
CORRECT ANSWER
d) A short to ground at "Z"
Question 2
A "Transfer case range position sensor circuit low" diagnostic trouble code (DTC) is stored
in a vehicle equipped with the four-wheel drive system shown above. Service information
indicates that this code is set when a short to ground is detected on the transfer case
position sensor signal circuit for more than two seconds. The stored DTC could be caused
by a short to ground at point:
a) W
b) X
c) Y
d) Z
CORRECT ANSWER

,b) X
Question 3
A vehicle equipped with the all-wheel drive (AWD) control system shown above will not
illuminate the AWD light under any operating conditions. During diagnosis, the voltage at
pin #4 measures 12 volts. When pin #3 is grounded, the AWD light illuminates. The most
likely cause is:
a) An open fuse to the AWD control unit
b) A failed AWD shift lock switch
c) A failed AWD control unit
d) An open AWD solenoid
CORRECT ANSWER
b) A failed AWD shift lock switch
Question 4
A vehicle equipped with the all-wheel drive (AWD) control system shown above will not
function under any condition. During diagnosis, the voltage at the fuse measures 12 volts,
at pin #4 .01 volts, with the connector to the control unit disconnected, and using an
ohmmeter testing for continuity to ground the technician finds OL at pin #3 when the AWD
switch is open, near zero from pin #3 when the switch is closed, and OL with the ohm
meter at pin #6. Which of the following could cause this condition?
a) An open fuse to the AWD control unit
b) A failed AWD shift lock switch
c) A failed AWD control unit
d) An open AWD solenoid
CORRECT ANSWER

Question 5
The fluid of a transfer-case is being drained and is found to contain plastic particles.
Technician A says it can be a worn transfer-case shift fork inserts. Technician B says it can
be a worn transfer case chain
Who is right?
a) Technician A only
b) Technician B only
c) Both A and B
d) Neither A nor B
CORRECT ANSWER
a) Technician A only
Question 6
A four-wheel drive transfer case has loud noise in four-wheel low range only.
Technician A says that a bad front output bearing could be the cause. Technician B says
that a damaged planetary gear set could be the cause.
Who is right?
a) Technician A only
b) Technician B only
c) Both A and B
