ABS and Traction Control System Inspection Checklist
This ABS and traction control system inspection checklist ensures proper function of anti-lock braking, electronic stability control, and traction control systems required on all new US vehicles since 2012 per FMVSS 126. Wheel speed sensors are the most common fault cause. Aligned with ASE A5 brakes and A6 electrical certification standards and FMVSS 135 brake system requirements.
- Industry: Automotive
- Frequency: Annually / Per ABS or ESC Warning Light
- Estimated Time: 30-60 minutes
- Role: ASE A5/A6 Certified Technician
- Total Items: 27
- Compliance: FMVSS 126 (Electronic Stability Control), FMVSS 135 (Light Vehicle Brake Systems), ASE A5 Brakes Certification, ASE A6 Electrical/Electronic Systems, SAE J2522 ABS Performance Standard
Initial Module Scan
Scan all chassis modules before physical inspection.
- ABS/ESC control module scanned for all current and pending fault codes?
- All codes documented with module, code number, description, and status?
- Related modules scanned - BCM, TCM, steering angle sensor for contributing faults?
- Live wheel speed data captured from all four wheels during slow roll test?
- Brake fluid at correct level - low fluid can trigger ABS pump faults?
Wheel Speed Sensor Inspection
Most common ABS/ESC fault cause - inspect thoroughly.
- Suspect sensor resistance tested - typically 1000-2500 ohms for passive sensors?
- Wheel speed sensor air gap within specification where adjustable?
- ABS tone rings inspected for missing teeth, cracks, or metallic debris?
- Sensor wiring harnesses inspected for chafing, damage, and secure routing?
- Wheel speed sensor connectors clean, undamaged, and fully seated?
- Wheel speed sensors securely mounted in bore with no looseness or excessive play?
ABS Hydraulic Modulator and Pump
Verify ABS hydraulic system function.
- ABS pump motor tested via bi-directional scan command - motor runs smoothly?
- No brake fluid leaks from ABS modulator or hydraulic lines?
- ABS solenoid valves commanded individually with bi-directional test where supported?
- Brake pedal firm with no sponginess indicating air in ABS modulator?
- ABS does not activate during normal stops on dry pavement?
ESC and Traction Control Verification
Verify ESC and TCS function and sensor calibration.
- Steering angle sensor calibration performed after any steering or alignment work?
- Yaw rate sensor reading near zero on level stationary vehicle?
- ESC warning light extinguished after fault correction and code clear?
- Traction control confirmed active in live data - intervenes during controlled wheel spin?
- Road test confirms no ABS or ESC warning lights during normal driving?
Final Verification and Documentation
Confirm all systems operational and document service.
- Post-repair scan confirms no remaining ABS, ESC, or related codes?
- All brake and stability warning lights extinguished after repair?
- ESC confirmed active and not disabled by driver at delivery?
- Related brake system services (pads, rotors, fluid) addressed or recommended while vehicle is in shop?
- ABS/ESC service documented on RO with all codes, repairs, and test results?
- Customer advised of any ABS components approaching service life?
