Thanks for the offer BlackDuck. I have just ordered a cd so will wait for a few days and attack it.

Hi Turtle59
Im interested to know how you resolved your exhaust brake problem... I have the reverse problem with my fg84. Dash light is on, fuse looks ok but no brake
Thanx

If you turn the engine warming switch on, does the exhaust brake engage?

No, doesnt work with engine warm switch on.
I'm interested in your resolve to.....I to have a fg84 the problem is the exhaust brake stays on intermittly then it goes into limp mode Mitsubishi have no clue

Sorry it has been a while since I posted this issue and since then my life has been thrown into a tail spin.
I have been to 3 auto electricians who had limited ideas and even less clues then I got sent to see a friend of a guy I work with and he had many clues and even more ideas. He is of the belief the problem is in the switch under the steering wheel that also controls the indicators and wipers etc. I think he called it a combination cluster or some such thing.
But as I said due to the tail spin I have not had a chance to pursue another switch. If you happen to know where I can get one for a fair price I would be interested... Then it might prompt me to do something about it.

Not sure if it helps, but on mine which is a fair bit older, 96 FG637, when I got it the exhaust brake did not work, but light came on etc when you moved the lever. Turned out the brake was seized closed, not so good for the performance, or what I thought was an exhaust leak, but turned out to be an overheated cracked exhaust manifold, so one new exhaust manifold and exhaust brake fitted and all good.
Occasionally it still doesn't work and had me scratching my head, but turned out to be simple, the spring on the accelerator pedal was not allowing the pedal to return fully to it's non pressed state, preventing the micro-switch from activating it, just needed to give the pedal a pull up with my foot and the brake would work again

.Here goes for digging up an old thread...
I have had my truck at an auto electrician for the day to try to work out what is actually wrong with my exhaust brake. His conclusion is that the issue is in the ECU. His suggestion is either get another ECU or get this one repaired.
What says the brains trust. Repair or replace. (Probably from the wreckers I guess.)

It seems very strange to me that if the ECU was faulty that the only issue you would have is the exhaust brake.
I have no idea how your auto electrician came to that conclusion, but if I were fault finding this issue I would follow the circuit diagram, isolating OEM wiring sections, working backwards from the exhaust brake.
Blaming the ECU seems like a bit of a stretch.

That was my thought as well. All things are possible, but most of the time it comes down to a mechanical failure not the computer, unless there is obvious environmental damage like water ingress.

I have a 2001 Fg and have the same issues with mine.
I tried plumbing up the exhaust break to the vacuum tank, bypassing the whole electrical side and it still didn't work.
I guessed that maybe the diaphragm is stuffed or butterfly valve seized.
I can move the butterfly valve myself so that's not it.....
I've given up at the moment.
