DPB_a007_PMCLeakageDetected
Power braking assist reduced
What does the DPB_a007_PMCLeakageDetected alert mean?
A brake fluid volume leak is detected in the master cylinder.
What you'll see in your Tesla
- Power braking assist reduced
- Braking may require increased effort
What triggers it
Loss of brake fluid in the tandem master cyclinder or pedal feel simulator. The monitoring calculates a leakage rate in the master cyclinder out of the volume loss over time during a brake event. An alert is set if the caclulated leakage rate exceeds a critical threshold. This threshold is a result of the vehicle backup calculation and is therefore vehicle-specific.
When it clears
Good Check is performed after a monitored brake event if the calculated leakage rate is in an uncritical range.
Potential impact
System will be running with internal degraded pedal map. Braking may require increased effort.
