Hi Susan
Try the following
B17 Foot brake fault.
Foot potentiometer or brake microswitch is failure.
When key switch is turned on, the input voltage (CN6-8) in the MPU board is under 0-15V. or over 3.13V
Or it is under0.78Vwith the actuator of the brake microswitch turned off.
Or it is over 2.4V with the actuator of the brake micro switch turned on.
