fault codes
I was hoping someone could help me.

I am trying to find out what fault codes could be read trough the serial port of the controller. So far I found out that FB=00 means normal and FB=20 means precharging. What would be the numbers for the rest?

the documentation list the following HPL, overspeed, overtemp, and no throttle or current sensor. Are there any others?

Also what is the meaning of HPL?

Apologize if this has been mentioned before, I did try to look for it but I could not find much.

You may want to provide a few more details... like what the heck you are working with?

Nvm, didn't pay attention to the forum category

nice way of increasing posts count. Any body else that could help me out. By the way this is for an app I am working on to display the cougar's data, sort of like the "EV LCD Instrumentation" or the "rtd explorer" but with larger fonts so I can see them on a larger display while driving.

That is high pedal lockout. Accelerator pressed while turning on the key switch.

#define THROTTLE_FAULT (1 << 0)
#define VREF_FAULT (1 << 1)
#define PRECHARGE_WAIT (1 << 5)
#define MOTOR_OS_FAULT (1 << 6)
#define HPL_FAULT (1 << 7)

vref fault means the current sensor is unplugged or broken.
throttle fault means the throttle is probably unplugged.
precharge_wait means the capacitors are charging up
HPL_fault is high pedal lockout (like Alvin was saying).
motor_os_fault is when the motor overspeed is tripped. it must be enabled though.
