On the dash of my holden rodeo there is a red light saying check 4wd and I cant seem to engage 4wd when pressing 4h or 4l ...I took my ute to a garage and they hooked it up to a machine that's supposed to tell u whats wrong and turn out the light but I have had no luck in doing so ,is there any advice on what could be wrong or how to fix this problem ?

I would first check the wires on the transfer case for possible damage at the 2wd/4wd switch.

I had this happen to a 1999 4x4 LS and my sisters boyfriend mentioned to periodically turn 4x4 on/off at least once a month.
What I did was go down a stretch of road slowly and attempt to turn it on/off till it became unstuck.
Drove around 10 miles on a road that was hardly used...to get the stupid light to quit flashing I had to put it in park and try to creep forward ---while using off settiing or put in park then reverse...while using the off -setting on 4x4. My patience paid off. They get sticky...you must be cautious... because there is a way to cause vibration and then it won't start...some deadman feature that I experienced once and the LWD must have slipped in a little and I had to look at everything.
Mine is an Automatic with the shift on the floor...that can get sticky too.

Good luck and hope this helps...mine had lots of growing pains but I get 23 mpg and it runs/idles better and the only gremlin left is some short in the dash which leaves the lights D/3 (one or both on)for the shift indicator on:)

SOURCE: what position must the 4wd

Hello marcampbell2, your escudo should be in 4H for highway use,the N position is used for towing purposes.take care and drive safe

SOURCE: 2005 chevy 1500 HD, 4 low will not engage.

I cannot understand why u would ever need 4L but anyway try this: after not working once move your vehicle about 6 inches backwards then try again. if no results move veh fwd about 6 inches and try again. if this doesnt word, im lost. good luck. ps: dont engage emerg brake

SOURCE: it's a holden rodeo turbo/diesel 2005.check 4wd light on

A mere 2,400km into the life of my 07 Rodeo TD 4WD, I used 4L for about 2km of medium-steep/slippery track. After stopping and selecting 2WD the 'Check 4WD' light appeared, meaning I was stuck in 2WD for the rest of that trip. Luckily I was able to complete the trip in 2WD without incident.

The dealer blamed me for 'not following the instructions in the manual' (utter codswallop), 'fixed' it, and very reluctantly gave me a scribbled set of instructions on resetting the system, which I've included below.

When I suggested that these instructions should be included in the manual, the response was 'not necessary if owners use the system correctly'. More cods.

Here's how to reset it:

1. Ignition off, hold all 3 buttons (2H, 4H & 4L) in together

2. Switch ignition on to 'reds' position (last position before start)

3. Hold in this state for 30 seconds

Hope this may be of use !!
