04 titan locks into 4h but 4wd light dont come on diagram that shows wheels shows front wheels are locked,when shift to 4lo sometimes it locks sometimes light just blinks

K or savana 1500? I will guess K1500 4WD.
driving on snow or offload?
4Lo, shifting is best at 1 to mph, a dead slow crawl.
what transfer as is here.? (RPO list not told or VIN)

SOME ARE FULL TIME OTHER PART TIME,
SOME HAVE A LOCK FOR PART TIME MODE.


for sure this truck is not AWD all wheel drive (not full time)
if not off road/or ice. it puts huge strains on the drive line.
in 4wd the axles clock.
The 4L and 4H are for offroad only, and on ice.
not pavement free of ice.
you will lock and wind up the axles and will not shift out of 4wd
and steering fights you (see that)
to cure this windup, move one or more tires to ice or dirt. and shift
slowly at 1mph or less.

page 2-22 in your glove box manual states and I quote





RTM, see this means not full time AWD

when tires are on ICE you are in effect, offroad.

Did you reverse more than 10 metres? Sounds like the hubs are locked into 4wd.this will work if you have auto hubs.but sometimes you have to turn the hub manually if they don't disengage.if you have gone some time or distance in 4wd

replace the locking hubs a sit appears the lock splines are damaged.

it is not broken it is operator error
Part time 4wd is only for off road or on ICE
never for pavement or it will wind up and bind up.
never good that.

I will nor read the uses guide(glovebox) to you.
the car came as part time only ,like my 08 wrangler
or has select track that has both, do not use part time there either.

the 4 FULL TIME mode allows the front and rear wheels to rotate at different speeds which eliminates driveline binding and component wear that is normally associated with driving the vehicle in the 4 PART TIME position on dry hard surfaced roads. This feature provides the safety, security,and convenience of operating in 4-wheel drive at alltimes regardless of road conditions.When additional traction is required the 4 PART TIMEand 4LO positions can be used to lock the front and reardriveshafts together through the transfer case inter-axledifferential and force the front and rear driveshafts torotate at the same speed. This is accomplished by simplymoving the shift lever to these positions. The 4 PARTTIME and 4LO positions are intended for loose, slipperyroad surfaces only. Driving in the 4 PART TIME and 4LOpositions on dry hard surfaced roads may cause in-creased tire wear and damage to driveline component

the cure is easy now
put at least 1 tire offroad or on ice.
then dead slow crawl in partime 4wd slow and shift to Neutral or 2w or FULL TIME.
as the case may be, get out of part time 4L or 4H
as you crawl on say slipper dirt the drive line un winds and un binds
and the selector un jams.

You can operate the transfer switch either when the vehicle is stopped or while the vehicle is moving. I always operate the switch while stopped. Put the shift lever in neutral and step on the brake with the front wheels pointed straight forward. Now switch from 4H lock to 4H. If no immediate response, turn the steering wheel slightly back and forth and it should shift to 4H for you.

Hi - Here is instruction how to do.

From N to 4H

Stop the vehicle completely, place the

transmission in "N" (Neutral) and depress

the brake pedal and the clutch pedal fully

(if equipped), then push in and turn the

switch to shift into "4H".

From 4H to 4H LOCK

You can operate the transfer switch either

when the vehicle is stopped or while the

vehicle is moving.

Position the front wheels straight ahead

and turn the switch to shift into "4H LOCK".

If the vehicle is moving, we recommend

that the speed be less than 100 km/h (60

mph) during this operation.

NOTE:

• When shifting between the transfer

switch position and the transfer gear

position is unmatched, all 4WD indicators

will blink and the buzzer will sound.

• If it is difficult to shift between "4H" and

"4H LOCK" while the vehicle is moving,

try accelerating and decelerating your

vehicle several times after turning the

transfer switch. Be sure to wait until traffic

conditions allow you to accelerate and

decelerate safety before using this procedure.

From 4H LOCK to 4L LOCK

Stop the vehicle completely, place the

transmission in "N" (Neutral) and depress

the brake pedal and the clutch pedal fully

(if equipped), then push in and turn the

switch to shift into "4L LOCK".

From 4L LOCK to 4H LOCK

Stop the vehicle completely, place the

transmission in "N" (Neutral) and depress

the brake pedal and the clutch pedal fully

(if equipped), then push in and turn the

switch to shift into "4H LOCK".

From 4H LOCK to 4H

You can operate the transfer switch either

when the vehicle is stopped or while the

vehicle is moving.

Position the front wheels straight ahead

and turn the switch to shift into "4H". If the

vehicle is moving, we recommend that the

speed be less than 100 km/h (60 mph) during

this operation.

NOTE:

• When shifting between the transfer

switch position and the transfer gear

position is unmatched, all 4WD indicators

will blink and the buzzer will sound.

• If it is difficult to shift between "4H" and

"4H LOCK" while the vehicle is moving,

try accelerating and decelerating your

vehicle several times after turning the

transfer switch. Be sure to wait until traffic

conditions allow you to accelerate and

decelerate safety before using this procedure.

From 4H to N

64J209

Stop the vehicle completely, place the

transmission in "N" (Neutral) and depress

the brake pedal and the clutch pedal fully

(if equipped), then push in and turn the

switch to the mark (1) at the left of the "N"
position, and hold the switch in this posi-

tion for 5 seconds until the "N" indicator

blinks, then turn the switch to the "N" position.

When you turn the transfer switch to the

"N" position, "N" indicator will come on with

the buzzer sound.

CAUTION

• Be sure to stop the vehicle completely

before operating the transfer

switch to shift between "N" and

"4H", or between "4H LOCK" and

"4L LOCK".

• Do not shift between "4H" and "4H

LOCK" unless the front wheels are

in the straight-ahead position and

we recommend that the vehicle

speed be less than 100 km/h (60

mph).

Do not operate the transfer switch

while tires are racing.

• Do not operate your vehicle in "4H

LOCK" or "4L LOCK" on dry, hard

surfaces.

(Continued)

CAUTION

(Continued)

• Do not operate the vehicle while a

4WD mode indicator is blinking

except when shifting between "4H"

and "4L LOCK".

If you operate the vehicle while a

4WD mode indicator is blinking, a

buzzer will sound and the transfer

will shift to "N" (Neutral) to prevent

transfer case damage.

In this case, use the following procedure.

1) Depress the clutch pedal fully (if

equipped) or shift the automatic

transmission gearshift lever to the

"N" position.

2) Turn the transfer switch to the

position previously selected.
3) Operate the transfer switch again.

As far as your 4WD light problems, can't help you. The loose hose sounds like the front diff vent hose.

Sounds like the front wheel hubs are not locking in.

How may buttons for the 4X4 two , three , or four ? Do the lights flash ? Any messages - service four wheel drive system ? Which transfer case does it have ?

Transfer Case - NVG 246-NP8 (Two Speed Automatic)
The transfer case shift control module uses the VIN information for calculations that are required for the different calibrations used based on axle ratio, transmission, tire size, and engine. The system does not know which calibration to use without this information.
Transfer Case Encoder Motor
The transfer case encoder motor consists of a permanent magnet (PM) DC motor and gear reduction assembly. It is located on the left hand side (drivers side) of the transfer case. When activated it turns the sector shaft of the transfer case (clockwise or counter clockwise) to shift the transfer case. The encoder motor is controlled with a pulse width modulated (PWM) circuit within the transfer case shift control module. This circuit consists of a driver on both the Motor Feed A and Motor Feed B circuits. The encoder motor is bi-directional to allow the motor to shift the transfer case from 2HI or 4HI to NEUTRAL and 4LO positions.
Transfer Case Encoder
The encoder is mounted to the transfer case encoder motor assembly and is replaced as an assembly. The encoder converts the sector shaft position (representing a mode or range) into electrical signals inputs to the transfer case shift control module. The module can detect what position the transfer case is in by monitoring the 4 encoder channels (P, A, B, and C). These inputs translates into AUTO 4WD, 2H, 4H, NEUTRAL, and 4L or in transition between gears.
Transfer Case Motor Lock
The transfer case motor lock is used to provide a 2H, 4H, and 4L lock-up feature. When the lock circuit is energized, the transfer case encoder motor is allowed to turn. When the transfer case is placed 2H, 4H, or 4L the motor lock circuit has no power provided to it and the lock is applied. This assures that the transfer case remains in the current gear position. When AUTO 4WD is selected the motor lock remains applied until an adaptive mode (torque is applied to the front propshaft) is required. During an adaptive mode the motor lock circuit is energized and the motor lock is released, enabling the encoder motor to turn and apply torque to the front propshaft.


SERVICE indicator (4WD/AWD) Lamp
The SERVICE indicator (4WD/AWD) lamp is an integral part of the cluster and cannot be serviced separately. This lamp is used to inform the driver of the vehicle of malfunctions within the automatic transfer case (ATC) system. The SERVICE indicator (4WD/AWD) lamp is controlled by the transfer case shift control module via a Class 2 message or by a Sevice Indicator Control Circuit.

The first thing to do before assuming it's a loose wire would be to have it checked for codes , auto zone , advance etc... can not check this codes .

If you know nothing about this , your best bet would be to take it to a qualified repair shop .

welcome to part time 4wd, its for ice and offroad ONLY.
rule #1 PT 4wd needs at least 1 tire on ice or say dirt.
if not it will WIND UP AND BIND UP and damage the transfer case chain. (i see you did that)!!!
also the locks love to fail, fixed many.
they need greasing every 15k miles, per the book .
its a constant service, and if water gets inside, AS ALL DO.
then more service. on the wheel locks.
if one fails the whole axle fails in 4wd.(slips but no grind/bind)

got one tire on ICE or now,????
ICE or PACKED SNOW.
PT 4WD IS NOT ALL WHEEL DRIVE,

IT is never FOR DRY PAVEMENT
OR WATER WET PAVEMENT EVER.
IT'S FOR ICE. (ON THE ROAD)

the question is , as for ever 1944 jeeps to now, PT
is what if road is 1/2 ice,?
dry, then ice then dry then ice. dig?

answer, go to 2H and driver slower!!!
or sell car and get a 2004+ Vitara with full time 4wd
in USA suzuki is bugged out, sold all mine, they sux now.
never buy any suzuki in USA or CANADA
buy a real JEEP. (or Rav4 or >?) nor buy any ISUZU. here.
