What causes the ZZ light to come on?
1 Answers
ZZ light on refers to the ESP malfunction indicator light in a car. The reasons for it illuminating are as follows: Normal phenomenon: If the ESP malfunction light is flashing, it indicates that the system is currently active, which is a normal condition. Component signal loss: If the malfunction light stays on constantly without other warning lights illuminated, it is usually caused by signal loss from components of the vehicle stability system. Common faults include issues with the steering angle sensor, lateral acceleration sensor, or wheel speed sensor. Vehicle system failure: If it lights up together with the engine warning light or other system warning lights, it may be due to signal loss from a critical electrical component causing multiple vehicle systems to malfunction.
