Check to make sure you did not pinch a wire on the switch. It is on the transfer case. You may have shorted it.

Check the vacuum hoses and solenoids for the four wheel drive.

I have a Isuzu 300Dmax and it has done this twice. (Leaves the "four wheel drive check" light on) By pressing and holding the 2H, 2L, 4L switches simultaneously for about thirty Seconds it is supposed to reset the transmission ECU but this does not seem to work. (This is as per the owners manual).

I eventually took mine in to the dealer who fixed it and charged me. Underneath the drivers seat is the ECU for the transmission control. They took out the drivers seat and bridged out some pins to reset the memory, which turned out the light and all was well.

I spoke to them nicely and they kindly gave me a copy of the procedure from the workshop manual - See attached. I suggest that Isuzu owners stick a copy in the cubbyhole together with the correct size torx and socket as well as some soldered cables to fit into the back of the connectors. Please note that you need long tinned solder tails (30mm) on the ends of your bridging wire your wire to reach right into the connectors and make contact with the right pins.

If you are stuck in 2H in the dunes the only way you are going to get out of there will be to have a cold one, pull out the drivers seat and reset the box.

Be careful and follow the instructions carefully as an Oops! In this area could possibly pop the ECU which could be costly.

Hope it helps.

Regards,

Greg
