I have a 99 isuzu trooper (jackaroo) 3.5 liter 4wd with torque on demand my jssue is the check rear wheel's lights blinks green then red if I put it in 4wd the rear wheel light indicator gose green the rear abs sensors are fine the vehical has TOD torque on demand. thanks czlouie

run the fault codes and look for a problem TCM unit

TO DO WHAT? not even the smallest hint on job or failure.>?
USA?
hubs, the rears have hubs to with disc brake option.rotor hubs.
I guess front hubs?.
guess 2, wheel bearing hubs, and not 4wd axle locking hub units.
doing what?
brakes, wheel bearings, axle damage. 4wd axle bearings what?
the pages are 2wd pages, and 4 wd pages, which is yours?
is this your first time DIY ever. ? or first time 4wd?
guess 3, 4wd, how am I guessing....


names
Acura SLX
Chevrolet Trooper
Isuzu Bighorn
Holden Jackaroo

wow......
our usa book lists it as trooper only.
so ...

just B or B then A off? if you had b off, you'd see what?, a big nut.
that is locked to spindle shaft.
ill guess? wheel bearings are bad? (just in hub not spindle bearings bad... no matter this is first.)
so you do what. ? here are the steps.

that part"B" must be off first, see the bolts holding it, ?
B = auto locking hubs. or hub axle lockers.
you can see the caliber must come off, so, do so and tie them up.

1. "Place the Transfer shift in the 2H position.
2. Raise and support the front of the vehicle safely on jackstands. (rear tires chocked, and hand brake set hard)
3. Remove the wheel and tire assembly.
4. Loosen the hub to rotor retainer bolts.
5. Remove the brake caliper mounting bolts and carefully remove the caliper (along with the brake pads) from the rotor. Do not disconnect the brake line. Secure the caliper out of the way with the flexible line still connected.
6. Remove the hub nut using hub wrench J-29020-A or equivalent. ( special tool)
7. Remove the hub cap assembly retainer bolts. Remove the spindle nut, washers, and other components. Remove the hub/rotor, being careful not to drop the outer wheel bearings. As the hub/rotor is pulled forward, the outer wheel bearings will often fall forward.
8. Once the hub/rotor is removed, remove the retainer bolts securing the rotor and hub together. Inspect the hub and replace if needed."
9. end removal. install is next... (alldata.com covers this)

no.

The Isuzu 3.5's all burn about 1 quart between oil changes. It was an engineering flaw with that model engine. Some people have said that running full synthetic oil will correct the problem over time. Either way, it is extremely important that you check your oil regularly.

As for you second question: Torque on demand has at its heart wheel speed sensors which typically are the issue. Having a wheel speed sensor replaced will set you back about $300.

I hope I was helpful.

I have the exact same problem. I can lock it in low range with the shifter but the auto push button doesn't work. Hope someone knows something./

Just press the 4wd button on the dash at any speed up to about 40mph and press again to come out .
When you turn the key on and the oil and battery lights are on the little green 4wd light should be on too if its flashing or not on check your fuses in the drivers footwell.

It is Torque On Demand. When you are stopped there is no need for the front end to be engaged, no demand. Once you start moving, the lights should begin working as the demand for four wheel drive engagement increases, if the conditions require four wheel drive. It's the way the system works. Enjoy!

get a code reader and see what codes it pulls

check the the 2 vsv near the front axle. They are stuck, just take apart and clean.

not transfer case motor....there is none on a rodeo....trooper has torque on demand.....rodeo problem is likely shift on fly mtr...mounted on front axle....if u dont use 4wd regularly it sticks and gets stuck.
