TRANSFER CASE VERIFICATION TEST
1.
Disconnect all jumper wires and reconnect all previously disconnected components and connectors.
With the scan tool, select clear Stored DTCs.
Make sure that all accessories are turned off and that the battery is fully charged.
Test drive the vehicle in each Transfer Case range and verify proper operation in each range.
To select or deselect 2WD, AWD or 4HI mode, vehicle speed must be below 88 Kmh(55 mph) with all wheels
at vehicle speed.
Shifts will not take place with a wheel speed difference of greater than 21 Kmh (13 mph) between the front
and rear wheels.
To select or deselect 4LO (if equipped), vehicle speed must be below 5 Kmh (3mph) with the ignition ON and
the transmission in neutral (auto trans) or the clutch pedal pressed (man trans).
To select or deselect Transfer Case Neutral, vehicle speed must be 0 Kmh (0 mph) with the ignition ON,
engine OFF, the brake pedal applied, and the transmission in neutral (autotrans) or the clutch pedal pressed
(man trans). Press the Neutral button (if equipped) on the Transfer Case Selector Switch until the Neutral Indi-
cator is illuminated.
WARNING: Apply the parking brake. The vehicle may roll with the Transfer Case in neutral.
To verify that the Transfer Case is in Neutral, shift the automatic transmission into reverse and release the
brake pedal for three seconds or shift the manual transmission into gear andslowlyreleasetheclutchpedal.
There should be no vehicle movement if the Transfer Case is in Neutral.
With the scan tool, select View DTCs in the Totally Integrated Power Module(TIPM) and in the Instrument Cluster.
Are there any DTCs present in the Totally Integrated Power Module (TIPM) orin the Instrument Cluster?
Ye s>>
Return to the symptom list and perform the appropriate diagnostic test.
No>>
Repair is complete.

REMOVAL
WARNING: On vehicles equipped with airbags, disable the airbag system before attempting any steering
wheel, steering column, seat belt tensioner, or instrument panel component diagnosis or service. Discon-
nect and isolate the battery negative (ground) cable, then wait two minutes for the airbag system capacitor
to discharge before performing further diagnosis or service. This is the only sure way to disable the airbag
system. Failure to take the proper precautions could result in accidentalairbag deployment and possible
personal injury or death.
1. Disconnect and isolate the negative battery cable.
2. Remove the steering column opening cover. (Refer
to 23 - BODY/INSTRUMENT PANEL/STEERING
COLUMN OPENING COVER - REMOVAL)
3. Remove the screws (2) that secure the top of the instrument cluster bezel(1) to the instrument panel.
4. Using a trim stick C-4755 or equivalent, disengage the two retainer clips that secure the top of the instrument
cluster bezel to the instrument panel.

5. Carefully disengage the instrument cluster bezel from the instrument panel opening and remove the bezel.
INSTALLATION
1. Install the instrument cluster bezel onto the instrument panel and fully engage the two retainer clips to the instru-
ment panel.
2. Install the screws (2) that secure the instrument cluster bezel to the instrument panel.
3. Install the steering column opening cover. (Refer to
23 - BODY/INSTRUMENT PANEL/STEERING
COLUMN OPENING COVER - INSTALLATION)
4. Connect the negative battery cable.

OUTLETS-AIR
DESCRIPTION
There are four defroster air outlets (1) in the defroster
grille (2) located on the top of the instrument panel
(3). The airflow from the defroster outlets is directed
by fixed vanes in the defroster grille and cannot be
adjusted. The defroster air outlets are not serviceable
from the defroster grille (Refer to 23 - BODY/INSTRU-
MENT PANEL/DEFROSTER GRILLE - REMOVAL).
There are two side window demister air outlets (4).
One located on each end of the instrument panel near
the A-pillar area. The airflow from the side window
demister air outlets is directed by fixed vanes in the
outlets and cannot be adjusted. The driver side win-
dow demister air outlet is serviced with the instrument
cluster bezel and the passenger side demister outlet is
serviced with the instrument panel cover (Refer to 23 -
BODY/INSTRUMENT PANEL/INSTRUMENT CLUS-
TER BEZEL - REMOVAL and 23 - BODY/INSTRU-
MENT PANEL/COVER-INSTRUMENT PANEL -
REMOVAL).
There are four instrument panel air outlets (5). One air outlet is located near the end of the instrument panel facing
the rear of the vehicle and two outlets are located on the instrument panel center bezel. Each of the instrument
panel air outlets contain a grille with movable vanes that are used to direct or shut off the flow of the conditioned air
leaving the instrument panel outlets. The driver side instrument panel air outlet is serviced with the instrument clus-
ter bezel, the passenger side instrument panel air outlet is serviced withthe instrument panel cover and the two
center air outlets are serviced with the center bezel (Refer to 23 - BODY/INSTRUMENT PANEL/INSTRUMENT
CLUSTER BEZEL - REMOVAL), (23 - BODY/INSTRUMENT PANEL/COVER-INSTRUMENTPA N E L - R E M O VA L )
and )23 - BODY/INSTRUMENT PANEL/INSTRUMENT PANEL CENTER BEZEL - REMOVAL).
On Mega Cab models there are two outlets located at
the rear of the center front seat. Each of the rear air
outlets contain a grille withmovable vanes that are
used to direct or shut off the flow of the conditioned air
leaving the outlets. The rear air outlets are not ser-
viceable.
