1. The most common fault of the brake system is the ABS lamp alarm, and the V64 hydraulic pump is faulty. This situation is mostly caused by the poor contact of the ABS hydraulic pump line solder joints. Generally, as long as the computer board is removed, a small opening is opened at the back, and the welding can be performed again, basically without replacing the ABS pump assembly.

2. Another fault is that the brake light is always on or off, mostly the brake light switch is broken, and the EPC light of the electronic throttle control system is on, and the 17087 fault code can be called up in the engine control unit. The brake switches are F and F47 (F is normally open and F47 is normally closed). When F is closed, the signal is sent to the brake light, ABS, engine ECU; at the same time, F47 is disconnected to the No. 15 of the engine ECU. When the brake switch fails, the engine ECU gets an error message and simultaneously lights up the EPC lamp of the electronic throttle control system and a fault code appears. In the case of an automatic transmission, the brake light switch is broken and the shift lever position cannot be moved because the automatic transmission shift lock solenoid N110 requires a brake signal. Here, I would like to tell you a simple way to remove all the rear brake bulbs (left, right, and high-position brake lights), so that you can move the gears without stepping on the brake pedal. This method is for other Volkswagen cars. Also applicable (Note: If the brake light is a light-emitting diode, there is no need to disconnect because the diode resistance is much larger than the lamp resistance).
This kind of Power Supply is also called industrial switching mode power supplies (SMPS) – It is a type of AC to DC, it obtains energy from the power grid, a DC high voltage is obtained through high voltage rectifier filtering, DC/DC converter obtains one or more stable DC voltage at the output end, and the power can be produced from several watts to several kilowatts for different occasions. The specifications of Switching Power Supply are various, the standard are 5V 12V 24V LED Power Supply, including single output, dual output and triple output power supply. They are widely used for LED strip, led module, led lamp and CCTV camera.
