UB6 to UBB plausible voltage divider drift alert (large deviation in the UB6 to UBB ratio).
<0.01% (Extremely rare)
Power braking assist reduced
Braking may require increased effort
System will be running in fully degraded state. Braking may require increased effort. Hydraulic Boost Compensation will be triggered when driver pressed brake pedal.
UB6 to UBB plausible voltage divider drift alert (large deviation in the UB6 to UBB ratio).
Possible voltage divider drift alert (with respect to UBB and UB6 measurement). Ratio between UBB and UB6 is checked every specified time. alert is set if the ratio is within specified range.
No internal issue is detected after changing operation cycle. If the condition persists, the DPB module may require replacement.
