How to repair the ABS warning light on a Jetta?

[AlexaLee]

Confirm the fault condition and symptoms, conduct a visual inspection of the system to check for any brake fluid leaks, damaged wiring, or low brake fluid levels. You can directly read the fault codes using a diagnostic scanner or retrieve the fault codes through the warning light, then refer to the repair manual to identify the fault condition represented by the codes. Based on the interpreted fault condition, use the necessary tools and equipment to conduct an in-depth inspection of the faulty area to confirm the fault location and cause. After the warning light no longer illuminates, perform a road test to confirm whether the system has resumed normal operation.
