2WD Light flashing contiuesly

Hello Newbie here
How can I get the 2WD light to stop flashing although I have pressed the 4 WD & 4WDL can it be deleted by an OBD reader?
I have also read about there being a Vacuum Pump supplying vacuum to the Drive Hubs but I don't want to go down that road yet,by the way it's late 2006 modle

Thanks

Keith

Hi Keith, I'm sure someone will be along to point you to the right info!
The vacuum is supplied from the intake manifold.

Hi Gaz,yeah been to that point took the pipe of the Vacuum Solenoid & was sucking good pardon the expression re-connected it to the solenoid took the bottom one off & noted with the Engine running no sucky,sucky I'm guessing the solenoid should be energised & delivering to the vacuum tank?coincidence or what not long had the Car and had new Back Box & Middle Section fitted new Clutch & Release Bearing fitted allegedly new Rear Shock Absorber & now this has happened apart from Front N/S Coil Spring has a piece missing & worst of all noticed when about to replace both belts theres a crack in the EngineBlock/Timing Case where the Altenator Adjusting Screw tightens think I got my hands full here

Nice pic by the way :o)

Cheers! Sorry to hear about your probs Keith..I have only had my '05 since the beginning of last December and I haven't had a look underneath mine yet. I have the flashing light too! I bought it from 45 miles away and didn't try the 4WD as wanted to be a good boy and get it on the grass first, and sure enough, it didn't engage 4WD and just got the flashing icon...Took it to my local garage and asked him to have a look for anything 'hanging off' and found one of the flexy pipes had come off, which he replaced but it still won't work!, as far as I can make out from the excellent posts on here, the ECU is waiting to get he signal that the hubs are locked..I'm wondering what is wrong? I roughly priced the major components to replace but it crept up to £1500+ so I've bought a pair of manual locking hubs and do what the other guys on here have said, and that is blank the inlet hole and short the contacts on the vacuum switch but not sure if that will stop the light from hell flashing? And will I be able to select low range too?
Have you thought of getting a mobile welder round to patch it in situ?

It doesn't take long to find the leak if you are methodical, but worse case scenario is you have to bypass the whole lot with silicon hose, which will cost about £10 and take around an hour.
If the leak is in the hub it's because you have a wheel bearing gone. Fix that before it kills you and the 4wd will come back to life.

Wow! Thanks for the informative reply.I only bought mine in January like you I didn't try all the features & am now left with this headache.I have been reading the threads on here & find the very informative as yours is,I was messing with the switches I did hear a bit of a 'clunk' sound after that the 2WD light was flashing I have checked the Vacuum pipe to the solenoid it seems I'm not getting 12volts to the solenoid so I need to trace that fault out if I can get a wiring diagram for my particular model '06' Jimmy's as for the Altenator mount probably change the belt first before it completely breaks away the grind into a little then pack it out with Aluminium Putty epoxy?
