DPB_a237_uCVoltageDividerDrift
Power braking assist reduced
What does the DPB_a237_uCVoltageDividerDrift alert mean?
UB_Valve to UBRD_INT plausi voltage divider drift alert (large deviation between UB_Valve to UBRD_INT voltage).
What you'll see in your Tesla
- Power braking assist reduced
- Braking may require increased effort
What triggers it
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.
When it clears
No internal issue is detected after changing operation cycle. If the condition persists, the DPB module may require replacement.
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.
