What Causes the ESP Warning Light to Illuminate?
1 Answers
ESP warning light illumination indicates a malfunction in the vehicle's electronic stability program system. Below are specific details about the ESP system: 1. Function: ESP, or Electronic Stability Program, analyzes vehicle driving state information transmitted from various sensors and issues commands to systems like ABS and EBD to help maintain dynamic balance. ESP ensures optimal vehicle stability under various conditions, with particularly noticeable effects during oversteer or understeer situations. 2. Oversteer scenario: When ESP system sensors detect and transmit signals to the control unit, it implements braking intervention on the outer front wheel. This unilateral single-wheel braking allows the vehicle to maintain stability without driver intervention. 3. Understeer scenario: Upon receiving sensor signals, the ESP control unit applies braking to the inner rear wheel during turns. Through such braking corrections, vehicle stability is maintained.
