back to the basics.
1 key up truck and check the voltage at the distribution board CA 205-3 (should be 0 volts)
2 check voltage at both the master and slave controller. CA 401-3 and CA403-3 if you have over 18 volts then the calibrate the ACC and brake pot you need a handset and manual to do this. It's the regular handset used on all EV 100 systems.

trouble code says if you have less than 18 volts which I had zero on pin three on the connector at module and replace the module. I have 36 volts when the accelerator switch is depressed at pin 3 and 0 volts when it is not depressed.
how do you calibrate the accelerator pot?
