ABS light

[no mufflers]

I am wiring a utility box on a 1997 f350 7.3 PSD and I cant get the brake lights to work. I am testing from the larger round plug at the end of the frame. other symptoms are, ABS light flashes 16 times, turn signals don't work, no power at brake switch. marker lights do work

here is a pic from my scanner of the possible codes. it is #16

The multi function switch could be bad.

Seems like a multitude of things.
12 relates to the fluid level sensor on the master.
11 would be worth looking at. Plus, brakes over ride turn signals/flashers.

I am getting power to one of the flasher terminals but no power at either of the brake switch wires.

what is the multi function switch?

The turn signal switch.
Also make sure the hazard switch isn't sticking.

is there anything else I can check that could cause the problem?

Start where there's power and work back. Lol
