Junergy Automotive Second Generation 4-Channel ABS (JN144-2)
Category：
Detail
In 2005, Juneng Company successfully developed the second generation four channel ABS, which greatly improved the ECU hardware circuit and control software compared to the first generation product. The anti lock brake system is abbreviated as ABS. The function is to automatically control the braking force of the brake when the car brakes, so that the wheels are not locked and are in a rolling and sliding state (with a slip rate of about 20%), to ensure that the adhesion between the wheels and the ground is at its maximum value.
The fault alarm of JN144-2 ABS still adopts the "automatic flashing code" method, with a flashing code of 2 digits. The fault codes are shown in the table below:
| The first group of fault codes (high nibble) | The second group of fault codes (low nibble) | ||
