Flashing 4WD lights when accelerating
 

I have a Mitsubishi Nativa (2005). Rarely take it off-road or use 4WD, but do occasionally use it.

Last month the 4WD lights started flashing when accelerating. They don't flash when doing a steady speed, but only when accelerating, especially between speeds of about 40km.hr and 110 km/hr.

Want to know if this is a big problem and what I can do to fix it.

Any tips / ideas appreciated - especially if you've had a similar problem with a Nativa (or other Mitsubishi 4x4 vehicle).

Thanks.

4WD lights Flashin
 

Hi I have Mitsubishi Nativa 2007 model. Suddenly I start seeing 4WD light flashing and occasionally ABS light comes on. When I stop the engine and restart ABS light disappears but 4WD light still on. Do you know what is the reason? What causes this issue? I have Nativa owner's manual but it doesn't give much detail on this issue. Appreciate your help
