AFMNA0AA – EPS-BLI HYG – User Manual
60) FUSE PROTECTION
Alarm 0XFFED = 226 Group #2 [M]:
- Cause:
This alarm occurs when the E-steering controller detects an
excess of the output energy in the last period. The diagnosis
evaluates the I
2
t value. The alarm is raised if the current is above
50 A 5 s long or above 25 A 20 s long.
- Remedy:
Check that the steering mechanics is not locked for whatever
reason. Check the gear and the home switch.
61) SLAVE WARN.
Alarm 0XFFED = 237 Group #4 [M]:
- Cause:
This alarm occurs in the MuC reporting a warning coming from the
SuC.
- Remedy:
Connect to the SuC and verify which is the root warning.
62) SLV LOCK MOT
Alarm 0XFFED = 237 Group #2 [M]:
- Cause:
This alarm occurs when the MuC detects the SuC requires to stop
the motor.
- Remedy:
Connect to the SuC and verify which is the root problem.
63) SLV STOP TRAC. WR
Alarm 0XFFED = 237 Group #3 [M]:
- Cause:
This alarm occurs when MuC detects SuC has stopped the traction
because of some anomaly.
- Remedy:
Re-cycle the key. If the alarm persists, replace the controller.
64) WAITING MASTER
Alarm 0XFFED = 237 Group #4 [S]:
- Cause:
This alarm occurs when SuC is unable to communicate with MuC.
- Remedy:
If the alarm is repetitive, replace the controller.
65) TFD&SAFE POS KO
Alarm 0XFFF6 = 246 Group #0 M]:
- Cause:
This alarm occurs when E-steering detects the high-side driver for
safety steer is not working right.
- Remedy:
Check the contacts A4 and A1. Check the TFD device if present. If
the alarm persists, replace the controller.
