To enhance the LB fault handling capability under FUSA TSR 1.4.2 requirement, to adopt currently LB hardwire or LIN signal “Headlamo_Low_Beam_Out” is used as activate source and redundant design. Besides, signal, so in case unintended hardwire lost, LDM shall report the LB Outage hardwire input failure report while LB hardwire active status and LIN signal "Headlamp_Low_Beams_Out" ON status mismatch mismatch, only to case that with "Headlamp_Low_Beams_Out" ON and no LB hardwire active within 1000ms. 1500ms.
LB |LB Hardwire ckt Headlamp_Low_Beams_Out |Headlamp_Low_Beams_Out LB Function LB Outage |LB Function|LB hardwire lost failure|
Active ON On No |Active|ON|On|No|
Inactive ON On Yes |Inactive|ON|Off|Yes|
Inactive OFF Off No |Inactive|OFF|Off|No|
Active |Active|OFF| OFF On| On Yes No|
