Failure modes for VIN
Failure modes for DIN
Failure modes for FIN
Failure modes for DFIN
Failure mode Effect
1 VIN Open VIN out of range, will create a VIN error =>
VIN=Predefined error value
a
a. Measure is controlled by CAN master and application as a result from the CAN error
message. Turning outputs off is controlled by CAN master unit and therefore delayed
maximum 2 bus cycles.
2 VIN S hort-circuited to +BAT VIN out of range, will create a VIN error =>
VIN=Predefined error value
a
3 VIN S hort-circuited to -BAT VIN out of range, will create a VIN error =>
VIN=Predefined error value
a
Failure mode Effect
1 DIN Open No effect on module, not detected
2 DIN S hort-circuited to +BAT No effect on module, not detected
3 DIN S hort-circuited to -BAT No effect on module, not detected
Failure mode Effect
1 FIN Open No effect on module, not detected
2 FIN S hort-circuit to +BAT No effect on module, not detected
3 FIN S hort-circuit to -BAT No effect on module, not detected
Failure mode Effect
1 DFIN Open No effect on module, not detected
2 DFIN S hort-circuit to +BAT No effect on module, not detected
3 DFIN S hort-circuit to -BAT No effect on module, not detected
