gav05 Posted November 24, 2013 Report Share Posted November 24, 2013 Hi all iv recently got a gv 1.6 petrol se 3dr 4x4 and iv checked it all over and it runs smoothly and the 4x4 system works but the 4x4 light flashes on and off in a pattern the vac pump runs and there is no noise from the transfer box. But some people say it should happen others say it shouldn't. My mates sj dose the same so im just not sure and no one can give me a answer. Any help appreciate.

Davyo Posted November 24, 2013 Report Share Posted November 24, 2013 Flashing light indicates a fault. Quote Link to comment Share on other sites More sharing options...
gav05 Posted November 24, 2013 Author Report Share Posted November 24, 2013 So vac pump or line then or could it be that the diff lock sensor at fault any ideas how to check it it doesn't flash constantly just every 5 seconds. Would the free wheeling hubs have and effect as in if there locked or in free ? Quote Link to comment Share on other sites More sharing options...
DannyNCC Posted November 24, 2013 Report Share Posted November 24, 2013 If it's flashing slow then fast then stop a second then slow then fast Count the slow flashes then the fast ones I'm not massively familiar with the older suzuki but can look tomorrow So vac pump or line then or could it be that the diff lock sensor at fault any ideas how to check it it doesn't flash constantly just every 5 seconds. Would the free wheeling hubs have and effect as in if there locked or in free ? Could be a number of things Doubt the hubs are a problem Check the lines So vac pump or line then or could it be that the diff lock sensor at fault any ideas how to check it it doesn't flash constantly just every 5 seconds.

gav05 Posted November 24, 2013 Author Report Share Posted November 24, 2013 Its the same all the time I timed it and its 5 seconds between flash and is always the same I did it on a lap timer and its always the same. How can I check if its the vac pump or solenoid. Dose this sound costly is there a way to take the air lock out other than swapping the axle with a standard diff lock like the old ones. Any help is much appreciated. Quote Link to comment Share on other sites More sharing options...
gav05 Posted November 25, 2013 Author Report Share Posted November 25, 2013 Looks smart plan to do the sane to mine just more interested in sorting the 4x4 system light.... if any one can help I checked the lines today and no split the vacuum pump behind the front bumper all working but there is a breather pipe clipped to the top of the rad that has air blowing out if I blow back down this the light stays on so is this a breather or should it be joined some where.

gameshooter93 Posted November 25, 2013 Report Share Posted November 25, 2013 Hi there, I had the same problem on my vitara a couple of months back. It is most likely the pipes or the vacuum pump, but could also be a leak in the diff. To find out which needs replacing, get a piece of pipe and connect it to the pump, and straight to the diff. If the light stays on then it means you have a leak in your pipes somewhere, but if it continues to flash, the vacuum pump needs replacing. Hope this makes sense!

gav05 Posted November 25, 2013 Author Report Share Posted November 25, 2013 Hi thanks for the reply yes that makes sense to me ill try it with a a new pipe and see. If its the vacuum pump has anyone got a idea of price or where I can get one from ie website. If its the diff leak well that's probably out of my Capability vut there is no oil on the diff so I hope its not that... Quote Link to comment Share on other sites More sharing options...
gameshooter93 Posted November 25, 2013 Report Share Posted November 25, 2013 I don't know where you would get a new pump from, but I was lucky to get one from my local scrapyard for £40, so I would try them first if there is any near you.

Guest rimotu66 Posted November 25, 2013 Report Share Posted November 25, 2013 Ive got the same problem with my Trooper but not had chance to get under it yet to have a look, sometimes (mosty when cold) it go's straight in and the light stops flashing, Mostly though it keeps flashing and sometimes when it does go in it doesn't come out, oh how I miss my old series LandRover with a lever and mechanical connection, why did they have to make things so hard ?

NIGHT SEARCHER Posted November 25, 2013 Report Share Posted November 25, 2013 (edited) In a lot of cases that have come in the garage it`s been 4x4 Transmission wind up. This is when the transfer box gets torqued up and won`t come out of 4 wheel drive. Go to a field or Supermarket car park when closed. Drive in Reverse going from left lock to right lock to un-wind the torque in the transfer box. And in many cases the vehicle will come out of 4x4 and lights stop flashing. You can try with the Vehicle stopped Engine running and the Drivers door open try switching the 4x4 switch. And you should hear a click from under the car if the Vac Solenoid is trying to disengage 4x4. Why ho why do they have to make everything electronic what was wrong with manual engagement of 4x4. Good luck. Edited November 25, 2013 by NIGHT SEARCHER Quote Link to comment Share on other sites More sharing options...

drum Posted November 29, 2013 Report Share Posted November 29, 2013 It will be the vac pump behind the front bumper on drivers side, common problem. I have a 05 2.0td and had exactly the same problem. Had a new one fitted at local Suzuki dealers under warranty. Price was £400+. Ridiculous price for a little pump. If it had not been under warranty I would of repaired it myself. The problem is there are two pistons in the pump that seal onto two rubber O rings. The end of the pistons become a bit rusty and don't seal properly on seals. All it needs is a bit if fine emery, and maybe new O rings. If you do a search on google there is a step by step guide in how to fix it. You can still drive car in 2 wheel mode with the pump removed while you work on it.

gav05 Posted December 4, 2013 Author Report Share Posted December 4, 2013 Vac pump replaced and all rubber tubes got 2 of the evil bay and the diff lock works and no more flashing light to say I'm happy is a understatement and iv got a spare as back up easy way to test the diff is jack one of the front side's up and try spin the wheel with 4h or 4l engaged if the wheel spins no lock if it doesn't its all working. Thanks for the help and comments lads. Quote Link to comment Share on other sites More sharing options...
