What causes the EPS and ABS lights to come on?

This may be caused by the generator not producing electricity. Reasons why a car generator does not produce electricity: 1. The intake air temperature or water temperature is too high, or the cooler is blocked: The intake air or water temperature should be reduced, and blockages in the cooler should be cleared. Before the issue is resolved, the generator load should be limited to reduce the generator temperature. 2. Too much or too little lubricating grease is added to the bearings: Lubricating grease should be added according to regulations, usually 1/2~1/3 of the bearing chamber (the upper limit for low speeds, the lower limit for high speeds), and it is advisable not to exceed 70% of the bearing chamber. 3. Bearing wear causes local overheating of the bearings: Check the bearings for noise. If stator and rotor friction is found, immediately shut down for maintenance or bearing replacement.
The simultaneous illumination of the EPS and ABS lights makes me think there's a serious issue with the vehicle, especially when I feel the steering wheel becoming heavier and the brakes a bit soft while driving. The most common cause is a sensor problem, such as a dirty or faulty wheel speed sensor, which affects the ABS system's anti-lock function. Meanwhile, the EPS system relies on the steering angle sensor—if that fails too, the power steering stops working. Another possibility is a glitch in the vehicle's ECU computer or low battery voltage, triggering false alarms across the system. I've tried checking for loose battery connections first, as sometimes small fixes solve the problem. If the lights remain on, don't take it lightly—especially during nighttime driving when accidents are more likely. It's best to head to a repair shop promptly to scan the codes. Professional diagnostics beat guesswork any day, and often, replacing sensors or clearing fault codes does the trick.
