This module uses fictional wheel speeds, yaw values and intervention thresholds to teach relationships. It does not provide OEM ABS/ESC/TCS thresholds, sensor specifications, bleed procedures, calibration values or authorization for unsafe skid testing. Use exact service information, approved lift/road-test procedures, controlled test conditions and architecture-specific calibration/bleed instructions.
Electronic brake control begins with believable vehicle-state evidence
13.4 covered the force-assist layer. This module adds wheel-slip and vehicle-stability control. Next planned module: 13.6 · Electronic Parking Brakes & Brake-by-Wire.
Trace the sensors, controller, hydraulic modulator and cross-system commands
Compare wheel speed, steering intent and yaw response before deciding whether intervention or diagnosis is needed
Values below are fictional teaching inputs. Real controllers use more signals, filtering and proprietary thresholds.
*Fictional teaching values. A wheel-speed difference can be real tire slip or a bad signal. Use vehicle state, cross-wheel comparison, circuit/target evidence and service information before deciding.
Separate real slip, sensor plausibility, calibration and hydraulic/control faults
Ordered ABS / TCS / ESC diagnostic workflow
Complete the sequence in order.

10-question knowledge check
Online electronic-brake reasoning is not hands-on brake-service competency
Use approved trainers/vehicles, exact service information and controlled conditions. Observe safe signal interpretation, physical inspection, command/response reasoning, calibration awareness and final verification.
