What does ESP/ASR malfunction mean?
2 Answers
ESP system malfunction is a no speed signal fault at the right front wheel (P, permanent fault). Within the automatic transmission control system: ABS(ESP)(CAN) vehicle speed fault (P, permanent fault); The engine control system issues a fault message: communication fault with the automatic transmission (P, permanent fault). Relevant information about ESP is as follows: 1. Introduction: Electronic Stability Program (ESP) is the abbreviation of Electronic-Stability-Program in English, translated as "electronic stability program" in Chinese. The function of the ESP system is to monitor the driving state of the car. When understeer or oversteer occurs during emergency obstacle avoidance or turning, the vehicle is prevented from deviating from the ideal trajectory. 2. Features of ESP: The most important feature of ESP is its proactiveness. If ABS is a passive reaction, ESP can prevent problems before they occur.
Oh dear, I've encountered this ESP/ASR malfunction several times, and it's really frustrating. ESP stands for Electronic Stability Program, which prevents the car from skidding or losing control during turns or sudden braking. ASR is the Anti-Slip Regulation system, specifically designed to manage wheel slippage, especially crucial on wet or slippery roads. When the warning light comes on, it usually indicates issues with these systems. Common causes include sensors clogged with mud or dust, aging wiring, or unstable battery voltage. I often drive an off-road vehicle on mountain roads, and once after rain, the light came on. Upon inspection, it turned out to be dirt on the wheel speed sensor, and it was resolved with a simple cleaning. However, don't take it lightly—when the system fails, drive slowly and avoid sharp turns, especially in snowy conditions where the risk is higher. The best course of action is to promptly visit a repair shop to use diagnostic tools to read the error codes and identify the root cause for repair. Regular maintenance, such as keeping the undercarriage clean and periodic sensor checks, can reduce the likelihood of such issues.
