Troubleshooting
Repeat the auto-teaching procedure.
38)
NO CAN MSG. 09
Cause
This fault is signaled when there is no communication with the supervisor uC.
Troubleshooting
This type of fault is not related to external components; replace the logic board.
39)
WRONG SET BAT. 05
Cause
At start-up, the controller checks the battery voltage (measured at key input)
and it verifies that it is within a range of ±20% around the nominal value.
Troubleshooting
- Check that the SET BATTERY parameter inside the ADJUSTMENT list
matches with the battery nominal voltage.
- Through the TESTER function, check that the KEY VOLTAGE reading
shows the same value as the key voltage measured with a voltmeter on pin
A1. If it does not match, then modify the ADJUST BATTERY parameter
according to the value read by the voltmeter.
- Replace the battery.
40)
IMS ERROR
Cause
At start-up, the controller checks the presence of IMS board. If the IMS board is
not well connected, this alarm appears.
Troubleshooting
- Replace the controller
41)
SHORT CIRCUIT
Cause
The controller continuously checks that the Three-phase bridge works properly
and that a short-circuit between motor phases is not present.
Troubleshooting
- Check that motor phases are correctly connected.
- Verify that motor phases are not shot-circuited.
- Replace the controller.
- In case the problem is not solved, replace the motor.
42)
SHORT CIRCUIT KO
Cause
The HW dedicated to detect faults on power bridge does not work properly
