SOURCE: Remove service brake system display from dashboard?

Check ABS system for codes. I have an '03 Silverado and have a faulty EBCM( Electronic Brake Control Module, "ABS module"). Can't reset anything. Only replacement of EBCM will fix it. Incidentally, if you have to replace it, you can check on Ebay for a rebuilt unit. You shouldn't have an issue with your "base" braking system though, if this is the case. ABS is electronically controlled and with or without it, your brakes will still function. I hope this helps.

SOURCE: 04 Kia Sorento stuck in 4WD Low

Usually the vehicle needs to be stopped and in Nuetral. Flip switch to 4X4 HIGH firts. It should come off. If it does not, put in drive and start moving slowly. Once in 4X4 HIGH you should have no problems going back and forth from 4X2 and 4X4 HIGH.

It's not necessary to use the 4X4 LOW setting in a snow storm in my opinion. I only use it if I'm off road going up a really steep grade or if I'm hauling something heavy up a hill. I only used it once because I was hauling a 26 foot pontoon boat out of the water. I strongly recommend using 4X4 in a snow storm or on slippery surfaces since you will get much better traction.

Good luck.

SOURCE: KIA Sorento 4WD not enguaging

Always make sure that whenever you engage into and out of 4x4, your gear lever is on N and not P.

so to reset it in now, switch on your engine with the hand brake up. set the gear lever to N, turn the knob to 4x4 Hi... wait 10 secs....switch it back to 2Hi...wait 10 secs and then return the gear lever to P and it should be ok.

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.

How do I turn 4wd on?


    • 1 Start your Dodge truck's engine.
    • 2 Turn the electronic transfer case from "2WD" to "4WD Lock" to engage the high range 4WD, if the dodge truck is equipped with an electronic transfer case; otherwise, shift the transfer case lever from "2H" to "4H." The electronic transfer case is located on the instrument panel and is marked with "2WD," "4WD Lock" and 4WD Low." The lever-equipped transfer case is located to the right of your leg and is marked with "2H," "4H" and "4L."
    • 3 Shift the transmission into "Neutral" while the vehicle is either stopped or rolling at 2 to 3 mph to begin engaging in the low range 4WD. Turn the electronic transfer case to "4WD Low," if the Dodge truck is equipped with an electronic transfer case; otherwise, shift the transfer case lever from "2H" or "4H" to "4L."
    Tips & Warnings
    • Indicator lights will come on and alert you that your vehicle is in either the high or low range of 4WD.
    • Do not engage in the low range of 4WD drive if the transmission is in gear; you must shift to "Neutral" first.
    • Many Dodge trucks allow you to shift from 2-wheel drive to the high range of 4WD at up to 55 mph--consult your truck's manual to ensure that this is possible. Do not exceed 55 mph while engaged in the high range of 4WD. Do not exceed 25 mph while engaged in the low range of 4WD.
    • Do not engage in 4WD unless you are on slipper or rocky roads.

Have 2005 chevy silverado stuck in 4wd-lo will not shift to 2wd all lights are out checked fuses are fine


If all the lights are out then the 4wd switch is bad but,if it won't come out of 4wd-low then the 4wd actuator is bad or stuck.The 4wd actuator is what engages the differential from 2wd to 4wd.HOPE THIS HELPS!!!

Wont shift from 2WD to 4WD. 4WD indicator switch blinks (light) but 2WD switch light never goes out.


check switch , fuse and relay if good check cable hoses and wiring at transfer are not damaged or disconnected -check actuator for proper movement actuator has a tendency to stick lube actuator rod if necessary

2002 4Runner - 4 wheel drive indicator won't go off


When the transfer case is not engaged for extended periods of time, the motor inside for the 4WD sticks. Try this: Raise the vehicle on a hoist, and do some tapping on the case while switching the 4WD indicator. Sometimes, this will free up the contacts inside the 4WD shift motor.

Hope this helps. Thank you for choosing FixYa for assistance.

Mitsubishi delicia 2.6 td (shogun engine). fails to release from 4wd so two front wheel lights flashing on dash. Its an auto but have tried usual things like re-engage then disengage and straight line...


Check the super select solenoids. I had the same problem with my pajero/montero io, when I released 4WD from 4H to 2H the two front wheels lights started flashing. They stopped flashing and was solid on when I re-engaged the 4WD (2H to 4H).

My problem was a failure in the 2H solenoid, it was not producing enough vacuum. The problem was intermitent at the begining and then was permanent.

I checked the solenoids in this way:
1) The solenoid that receives the vacuum in the botton is for 2H
2) The solenoid that receives the vacuum in the top is for 4H
3) Both solenoids operate in the same way, they only change in the way they transfering vacuum from top/botton to the exit pipe (2H or 4H). The difference is that one has the vacuum input on the top and the another one in the botton.
4) The default position when you disconnect the electronics is 4WD
5) Try disconnecting the electronics and switching the output pipe between the solenoids. This will put the solenoids on 4WD position and you changed the pipes, so the 4WD should disengage.

4WD should disengage if your 4H solenoid is OK, the ligths should now flash when you change from 2H to 4H because 4WD cannot engage because the pipes are switched. You can also check the vacuum of each solenoid with your finger on each one.

If this doesn't work, try to bypass the solenoids and connect the input vacuum hose to the 2H output pipe. If the lights doesn't turn off in 2H mode it's posible that you have different problem.

Good luck.
