Braking and stability control
PSM relies on wheel-speed, steering-angle and brake-pressure information. A warning can originate from a wheel-speed sensor, hub encoder, wiring, voltage supply or mechanical brake issue.
How a technician distinguishes possible causes
Read the PSM controller, compare wheel speeds, inspect brake wear and hydraulic condition, and check sensor circuits. For track-driven cars, assess rotor condition, pad compound, fluid and heat exposure separately from ordinary road maintenance.
Repair and post-repair verification
Verify brake function and warning-free operation after repair, including required calibrations.
Hybrid Panamera variants use regenerative braking and specialized electrical and thermal systems. A brake or charging message can have different causes from a conventional Panamera.
