THERMIC SENS.
KO
The output of the controller thermal
sensor is out of range.
Replace the controller.
251-CTRL ERR WRONG SET BAT.
At start-up, the controller checks the
battery voltage (measured at key input)
and it veries that it is within a range of
±20% around the nominal value.
Check the condition of the batteries.
Replace or charge.
253-CTRL ERR FIELD ORIENT. KO
The error between the estimated Id
(d-axis current) and the relative set point
is out of range.
Replace the controller.
254-CTRL ERR EB. DRIV.SHRT.
The EB driver is shorted.
The microcontroller detects a mismatch
between the set point and the feedback
at the EB output.
Check if there is a short or a low
impedance path between the
negative coil terminal and -B.
If no problem can be found, replace
the controller.
