Question: Why does the instrument prompt “Please check the ESP system” when BYD Song MAX is in reverse gear a little slower?
Answer: When the manual model of Song MAX is in reverse gear, if the gear is not engaged, the shift lever stays in the shift position for about 2s, and the combination instrument will prompt “Please check the FSP system”. At this time, the electronic body stability system reports the fault code “Reverse gear signal invalid”. This is a normal control strategy of the vehicle and does not affect the normal use of the vehicle. If the vehicle is not turned off, the prompt and fault code will always exist. At this time, you only need to turn off the vehicle or clear the fault code to eliminate the prompt.
