I just bought my 92 sc400 from a car lot. They don't know any history on the vehicle. The "trac" light is on. I checked the codes and they are 43 and 54. I talked to the dealer and they said that the accumulator is ussually the problem because they loose there charge. I read about bleeding the trac system. I did try to bleed the actuator. I open the bleeder on it and then started the car. it took about 5 seconds before any fluid started coming out. I closed the valve and reset the codes. I drove the car around the block. the trac light came back on immediately. When I returned home I opened the bleeder valve on the actuator with the engine off and fluid came out. The codes are still the same. The brake master cylinder is really dirty on the inside of the clear container and the brake fluid is really dark in color. I think I need to do a brake fluid flush. I have read alot of threads on it but I need to know if I need to bleed the master cylinder too or just the trac system first then each wheel cylinder? Can anybody tell me how to check to see if the accumulator is ok or what it takes to repair this issue? I have heated seats in my sc but they do not work. When I turn the switches on the lights come on but the seats don't heat up. Also can someone tell me if the bottom of the seats are the only thing that is heated or are the backs heated too?

I just found a hole in the pressure hose leading from the accumulator. I ordered the hose from the dealer it will be here in about 3 days. When I get it put on I'll let you know if I still get the trac light on. I also flushed the brake system. "WOW" alot better brake pedal. I still need the info on the heated seats.

only front seats heat up.

I know the rear seats don't heat up.I was asking about the back of the front seats or is it just the bottom of the front seats that heat up? Does anyone have an idea of what could be wrong with mine?

I put the high pressure hose on the accumulator and bled both the accumulator and the accuator and no more trac light or trouble codes. It was a hundred dollar repair. Now to fix my CEL trouble code 25.
