I need help
I have a Curtis 1238 -6501 (bought used) and used together with an Hpevs 31-01 ac motor

Status:
I have a curtis 1309 usb programmer Oem version
After start up it displays no system faults
I am able to perform motor characterization, wheels spinning and I get no error
On the programmer I am able to reed the following input:
Throttle pot (the voltage response fine to the throttle position ), all fine.
But throttle command and throttle map display always 0.0%

I am able to have the car driving very slow forward and backward, but it doesn’t respond to the throttle position at all.

How to figure out if controller is in “lim home” mode?

Any ideas what’s wrong?

Does it have a brake or regen input?

 

[Berno]

All disabled ( but not brake pot)

 

[remy_martian]

OK....

So what's the brake pot signal sitting at?

Is it possible to upload generic original firmware?

No brake pot used

But you're saying your controller thinks there is one, so you don't get the option of not hooking one up if so.

Hook up a pot, see if it fixes it.

I am not saying my controller thinks there is one

I state
Throttle pot (the voltage response fine to the throttle position ), all fine.
But throttle command and throttle map display always 0.0%

think I need to flash net virgin firmware to the controller
is it possible ?

 

[Berno]

Net=new

Again, get your head out of the throttle. If it thinks you are braking, you are going nowhere.

You've datafilled it to expect a brake pot. Leaving a brake presure sensor disconnected means it will not accelerate other than limp.

Wire a pot into the brake pot signals and see if it works.

I'm too busy to be repeating myself. Troubleshoot the problem.
