DPB_a237 — U C Voltage Divider Drift
Full alert identifier: DPB_a237_uCVoltageDividerDrift
Alert description
UB_Valve to UBRD_INT plausi voltage divider drift alert (large deviation between UB_Valve to UBRD_INT voltage).
Potential impact
System will be running in fully degraded state. Braking may require increased effort. Hydraulic Boost Compensation will be triggered when driver pressed brake pedal.
Set condition
Possible voltage divider drift alert (with respect to UB_Valve and UBRD_INT measurement). Voltage difference between UB_Valve and UBRD_INT is checked every specified time. alert is set if preconditions are met (UBRD_INT below active threshold) and the voltage difference exceeds a threshold.
Clear condition
No internal issue is detected after changing operation cycle. If the condition persists, the DPB module may require replacement.
