32) “EMERGENCY”

Cause:
The voltage on A3 is different than +Vbatt.

Troubleshooting:

-

If A3 is correctly connected to +Vbatt.

-

If the fuse on A3 is not damaged.

33) “FLASH CHECKSUM”

Cause:
The software was not correctly written into the flash memory or the flash
memory is damaged.
Troubleshooting:
This type of fault is not related to external components, replace the controller.

34) “CURRENT SENS. KO”

Cause:
One of the current sensor, used to measure the value of the current on the
motor phases, is damaged.
Troubleshooting:
This type of fault is not related to external components, replace the controller.
