There is another recall for the cruise control. This time it is about transmission issues and wiring to brakes and electrical issues. This could be a free recall repair.

SOURCE: I turn the electronic switch and the 4 wheel drive does not engag

Operationally vacuum holds the IWE ( Integrated Wheel Ends ) out, and once vac is removed the spring engages the IWE.

Lift and support the front of the truck so the front wheels are off the ground ( take safety precautions, chock wheels, jack stands, etc )
Key on, engage 4x4 and try to turn the front drive shaft.
If it turns it is a problem with the transfer case.
If it doesn't it is a front axle engagement problem.

- If the front drive shaft does not turn :
Shut of the truck ( still jacked up, and supported ) remove the vac lines from the IWE. The spring should push the gears in, without the vac line on.
Check the vent line ( tube that is routed into the engine compartment with nothing attached to it ), for blockages.
If the vent line is clear, and with the vac lines off the IWE should be engaged ( both front wheels locked ).
If they lock, the problem is with the IWE solenoid not shutting off vacuum to the IWEs. There is a TSB on the 2004-2006 IWE solenoids, a newer revision has been made, and used from 2007 and newer MYs.

Here is a block diagram of the IWE system

Here is a link to the TSB for the IWE solenoid in PDF format
http://my.voyager.net/~sscully/file_tsb06_08_15.pdf

Start with testing to see if the front drive shaft turns while in 4WD to know which way do go with the repairs, the usual route is the IWE vacuum system ( lines or solenoids ), but I have seen shift motors be a problem also.
If you find a vacuum problem, you can remove and plug the vacuum lines at the IWE, and leave the front hubs locked in all the time, until you can diagnoses where the issue is at.
Just don't try racing anyone or expecting stellar acceleration , pushing a dead axle is going to consume some HP.

Most likely the controller module is bad, or the actuator for the front axle has gone bad.

How do i check the front axle vacuum selonoid on a 2002 jeep wrangler


02 , just sold mine, best car ever. had, of many.

how do you know that.?

and what are the tires, touching, (dirt, snow,ice, grass , pavement)

what?

this car has part time 4wd, it is not AWD

its not a Grand cheerokee with AWD.

engaging 4wd on ice free pavement is wrong.

http://www.rubicon-trail.com/4WD101/driveline-bind.html



and my fsm states.

read the operators guide in the glove box, it will say....

"2WD is intended to be driven on normal street and highway conditions, such as HARD surfaced roads."

Then

"4H & 4L positions are intended for loose slippery road surfaces only and not intended for normal driving" (They assume paved streets are normal.)

"Driving in 4H or 4L positions on hard surfaces roads, will cause, increased tire wear, and damage to the drive line components."

Unqual tire sizes, will do the same damage. "circumference mismatched"

Last: "do not attmpet to make a shift, while only the front or rear wheels are spinning" No transfer case synchronizer exists and damage will result."
(kill the gear dogs, you will)

4L and 4H lights flashes when you try to engage either of them in 05 Isuzu Rodeo


this is a part time 4wd, not AWD.
and as such must not be run on dry ice free pavement.
so post if car is on said pavement.
test 4wD in DIRT, does it work now, or not?
if you keep doing it on dry pavement this happens.
see here
http://www.rubicon-trail.com/4WD101/driveline-bind.html

read the wiki on all system. and see what you can do and can not.

its not AWD, and has no CENTER differentiable gears.

2wd vs AWD


Page 13 of owner's manual says:
AdvanceTrac
(if equipped):
Illuminates when the AdvanceTrac
system is active. If the light remains
on, have the system serviced
immediately.
AWD locked (if equipped):
AWD
Illuminates when all wheel drive
LOCKED
(AWD) is engaged/activated. If the
light continues to flash, have the
system serviced.

Page 224:
ALL WHEEL DRIVE (AWD) SYSTEM (IF EQUIPPED)
Your vehicle may be equipped with an All Wheel Drive (AWD) transfer
case. With the AWD option, power is supplied to all four wheels
automatically with no need to shift between two-wheel drive and
four-wheel drive. If your vehicle is equipped with the AdvanceTrac
stability enhancement feature, you can change AWD modes, if desired,
by selecting AWD options through the message center.
For the lubricant specification and refill capacity of the AWD transfer
case refer to Maintenance and specifications chapter.
If your vehicle is equipped with AWD, a spare tire of a different
diameter than the road tires should never be used. Such a tire
could make the vehicle difficult to control as well as result in damage
to driveline components.
Utility and four-wheel drive vehicles are not designed for
cornering at speeds as high as passenger cars any more than
low-slung sports cars are designed to perform satisfactorily under
off-road conditions. Avoid sharp turns or abrupt maneuvers in these
vehicles.
The following sections, Normal operation, Autolock operation and
Disabling AWD, apply only to vehicles which allow the driver to change
AWD modes through the message center.
Normal operation (vehicles equipped with AdvanceTrac
During normal operation:
• the AWD system is in AWD AUTO mode (AWD LOCKED will
illuminate in the message center for four seconds when you first start
your vehicle). The AWD LOCKED indicator in the instrument cluster
will also come on.
• AWD AUTO mode can be overridden by pressing SETUP in the
message center. When you first press SETUP, AWD <AUTO> will be
displayed, then if you press RESET within four seconds of pressing
SETUP, AWD <LOCKED> will be displayed. AWD <LOCKED> provides
power to all four wheels constantly which allows you to operate your
vehicle in severe winter or off-road conditions such as deep snow, ice
or shallow sand. It is not recommended that you use AWD <LOCKED>
on dry pavement.

Page 225:
• AWD <LOCKED> can be cancelled by pressing RESET in the message
center. (The AWD LOCKED display in the message center will then
turn off and the display will return to AWD <AUTO> for four seconds
when the shift is complete.)
Autolock operation (vehicles equipped with AdvanceTrac
If the AWD system begins to overheat, the system will place itself in the
Autolock mode:
• the AWD LOCKED indicator light will illuminate in the instrument
cluster and AWD DISABLED <LOCKED> will be displayed in the
message center.
• AWD LOCKED will be displayed in the message center for four
seconds and a warning chime will sound. This condition may clear
without any action being taken by the driver.
• the AWD LOCKED indicator light in the instrument cluster will turn
off when the AWD system cools down.
• When the system is sufficiently cooled down, AWD AUTO RESTORED
will appear in the message center for four seconds and a warning
chime will sound.
Disabling AWD (vehicles equipped with AdvanceTrac
When a problem is detected in the AWD system:
• the AWD LOCKED indicator light in the instrument cluster will flash
eight times every two minutes in the message center.
• The message center will then display AWD DISABLED for four
seconds, then SEE OWNER'S MANUAL. A warning chime will also
sound. The warning displays and chime will continue until RESET is
pressed (which will clear the message from the display).
• AWD LOCKED can still be engaged by pressing SETUP (the message
center will display AWD <DISABLED> LOCKED), then pressing
RESET. The AWD LOCKED indicator light will illuminate in the
instrument cluster and the message center will display AWD
DISABLED <LOCKED>.
• To disable AWD, press RESET. The system will go back to AWD AUTO
mode momentarily, then the AWD LOCKED indicator light will flash in
the instrument cluster eight times every two minutes. The display will
then show AWD <DISABLED> LOCKED for four seconds and then
turn off.

Page 226:
• If a serious problem occurs with the AWD system, the AWD LOCKED
indicator light in the instrument cluster will flash 10 times every two
minutes. The message center will also display CHECK AWD and a
warning chime will sound. You can press SETUP to check the status of
the AWD system (which will display AWD <DISABLED> LOCKED),
but the AWD system will be disabled until the system is serviced.
Driving off-road with truck and utility vehicles
AWD vehicles are specially equipped for driving on sand, snow, mud and
rough terrain and have operating characteristics that are somewhat
different from conventional vehicles, both on and off the road.
When driving at slow speeds off-road under high outside temperatures,
use 1 (First) gear when possible. 1 (First) gear operation will maximize
the engine and transmission cooling capability.
Under severe operating conditions, the A/C may cycle on and off to
protect overheating of the engine.

How to ingage the for wheel drive


Yes the light should be on when it is in 4 wheel drive, either 4h or 4l, to engage it into 4h you need to lock the hubs then select 4h while moving. Now if u want to put it into 4L you need to first stop the truck, put it into neutral and then select 4L

If it is automatic transmission you must stop vehicle put it in neutral or "n" then put shifter that is indicates 2h 4h and 4L pull down to 4h if you are driving on highway or pull down then over and up to 4L if you are not going to be driving faster than 30mph.
