My exhaust brakes on my 1994 HZB50R Toyota Coaster have stopped working. I have checked the clutch and accelerator switches and they both have power and working, the light comes on in the dash though i don't get power to the exhaust brake solenoid. The fuses are OK. Does anyone have a wiring diagram of the exhaust brake system? Any help would be greatly appreciated.

Peter, I assume going by the model the engine is a 1HZ diesel. Is the exhaust brake a standard fitment, or after market?
If standard, maybe try whoever is the state dealer wherever you are for the Coaster busses.
From memory the 1HZ was actually a Hino engine, so maybe also a Hino truck dealership.
I'm pretty sure Hino is a subsidiary company of Toyota.

Thanks for your reply.
The exhaust brake is a standard fitment and the 1HZ motor is the same as in the early Toyota Landcruiser.
