What does automotive ABS fault code DRP mean?

If there is a problem with the speed sensor on the wheel, it is recommended to go to the 4S shop for maintenance.

The vehicle speed sensor detects the speed of the electronically controlled car, and the control computer uses this input signal to control engine idling, torque locking of the automatic transmission, shifting of the automatic transmission, opening and closing of the engine cooling fan, cruise control and other functions.

I have a car like this too, what's the reason for you? Is the ABS pump broken?

ABS is the English abbreviation of Anti-LockBrakeSystem, that is, "Brake Anti-lock Braking System". In the absence of ABS, if the emergency braking generally causes the tire to lock, the distance between the tire and the ground is sliding after the locking, so the braking distance will become longer. If the front wheel is locked, the car loses lateral steering force and is prone to deviation; If the rear wheel locks up, the rear wheel will lose lateral grip and is prone to tail flicking.

This is especially true on snowy roads, where emergency braking is more likely to occur. ABS is to control the retraction and release of brake oil pressure to achieve wheel locking control.

ESP is the abbreviation of English ElectronicsTabilityProgram, which is translated into Chinese as "Electronic Stability Program". This group of systems usually supports ABS and ASR (Drive Anti-Skid System, also known as Traction Control System). It analyzes the driving status information from each sensor and then sends a correction command to ABS and ASR to help the vehicle maintain dynamic balance.

ESP provides optimal stability in all conditions, especially in oversteer or understeer situations. ESPs generally need to install steering sensors, wheel sensors, side slip sensors, lateral acceleration sensors, etc. The ESP can monitor the car's driving status and automatically apply braking force to one or more wheels to keep the car running in the normal lane, and in some cases can even apply braking up to 150 times per second.

ESP is the general name for the electronic stability control system of the body, which is a system or program designed to improve the handling performance of the vehicle while effectively preventing the car from losing control when it reaches its dynamic limit. The electronic stability program improves overall vehicle safety and handling. When the ESP system works or fails, the fault light will be notified to prompt in the instrument cluster.

ABS is the automatic lock system of the wheels, and ESP is the body stability system, which should be something encountered in bad road conditions.

There is a problem with the brake light switch, just change it.
