All four wheels are in drive when all four tires are green. Could also be in f wheel drive low. 4x4 low is talked about also at the end of the video. You do not want to be driving at high speeds in 4x4 low, at lease with the 4x4 I have owned.

Check 4 w actuator.

Test the electric motor that engages the transfer case.

check battery connections or flat battery

4 wheel neutral vehicle will not move that for towing or moving around --put in 2wh --4hi or if have 4low transfer case has to be in a setting to move

that is ur part time 4 wheel drive light...check to see if the four wheel drive lever next to the shifter handle is in the part time 4 wheel drive ..if it is just move it to the 2 wheel drive position..

Before you pull the wheel (which involves removing the air bag unit) you can test the horn switch at its connector with the cable reel (newfangled horn ring). First remove the dashboard lower cover under the steering column. Remove the steering column upper and lower covers. Disconnect the dashboard wire harness connector (4 pins) from the cable reel. Check for continuity between the cable reel no.2 terminal (light green/blue stripe wire) and body ground in each horn switch position. There should be continuity when horn is pushed and no continuity when horn is released. If one or both continuity checks fail, then you'll have to remove the airbag and change out the cable reel.

D could stand for differental lock in

That light sounds like a differential lock or 4-wheel drive. This is usually found in 4-wheel drive and all-wheel drive vehicles. Being the light is "GREEN" and not amber or red tells me that it's not an abnormal problem.

Look around your dashboard or gearshifter for a button labeled 4x4 HI, 4x4 LO, 4x2 HI. sport/off road button, or a second, smaller shifter. Switch them around a little, and if it is a 4x4 selector, be sure when you drive on paved roads to have it set to 4x2 HI. 4x4 HI should only be used if you get stuck to help you get out (snow/mud) and 4x4 LO is only for off road driving (trail blazing/rock climbing/4-wheeling/mud bogging,etc.)

Also, check for any switches labled "DIFF LOCK" or 'AXLE LOCK". In most cars a green light is normal operations.

I hope I could help you find a solution to your problem.

Is it all wheel drive? I believe it's telling you it's in four wheel drive or the sen is going bad in the all wheel drive
