Description
This alarm occurs if the pump motor temperature read by
analog sensor, overtakesthe MOTOR SHUTDOWN
value setted in submenu ADJUSTMENT. If this warning
occurs the motor rpm begin to decrease and motor
current and speed decrease linearly with the
temperature increasing.
Troubleshooting :
If "MOTOR TC START" warning occurs when pump
motor is cold, check the wiring. If all is ok, replace logic
board.
Cause :
The maximum current gain parameters are at the default
values, which means the maximum current adjustment
procedure has not been carried out yet.
Troubleshooting :
Ask the assistance of a Hyundai technician to do the
correct adjustment procedure of the current gain
parameters.
Cause :
This alarm occurs when the A/D conversion of the
analog inputs gives frozen value, on all of the converted
signals, for more than 400msec. The goal of this
diagnosis is to detect a failure of the A/D converter or a
problem in the code flow that omits the refreshing of the
analog signal conversion.
Troubleshooting :
If the problem occurs permanently it is necessary to
substitute the controller.

This warning occurs only if CAN BUS is PRESENT. At
key-on the eps-ac0 asks to the traction controller to send
a list of parameters via CAN BUS. From the request until
the parameters are correctly relieved, this warning
occurs. The steer is not activated yet, and the safety
relays remain open when this warning is present.
