Isuzu Trooper 2003 - 4 wheel drive problem - Fixed #

Posted by Gerald Oliver on October 30, 2010, 8:38 pm

Year of Manufacture *: 2003
( Optional ) Engine Code or CC: Engine code- RJM / Transmission code - RNK

We have a Isuzu Trooper 3 Litre DOHC turbo diesel 2003.
Engine code - RJM, Transmission code - RNK.

The problem is it will not come out of 4 wheel drive, it then we think it winds itself up and then it will not go backwards when put in reverse.

It will go in and out of 4 wheel drive when it is in hi box.
It will go it to 4 wheel drive in low box but it will not come out of 4 wheel drive while in low box.
This vehicle has a problem with the 4 wheel drive light on the dashboard because the light is flashing all the time when it is out of 4 wheel drive, The light is on all the time when it is in 4 wheel drive.

I went out to recover it with a trailer and on returning to our yard it then backed of the trailer, it also drives ok.

WE did not know if anyone could shed any light on the problem or give us any ideas or places we could try to locate the problem.

I seam to remember some modulating valves that play up and give the type of faults you have.

THE PROBLEM WAS THERE WAS A BROKEN WIRE ON THE VACUUM VALVES ON THE FRONT AXLE.
I REJOINED THE WIRE AND THE PROBLEM HAD GONE.
SO MANY THANKS TO ALL WHO HAD HELPED, GERALD.
