How to Troubleshoot ABS Light Illumination?

[MaryFitz]

ABS light illumination troubleshooting methods: 1. Confirm the fault condition and symptoms; 2. Conduct a visual inspection of the system to check for brake fluid leaks, damaged wires, loose connectors, low brake fluid level, etc.; 3. Read the fault codes, either directly using a diagnostic scanner or by interpreting the warning light codes and then referring to the service manual for the corresponding fault conditions; 4. Based on the interpreted fault conditions, use necessary tools and instruments to conduct an in-depth inspection of the faulty area to confirm the fault location and cause; 5. Resolve the fault; 6. Clear the fault codes; 7. Check if the warning light remains illuminated. If the warning light stays on, there may still be a fault in the system, or the fault may have been resolved but the fault codes were not cleared.
