起步发动机，查看ABS系统的数据流，选择004组数据块，该数据块共有4

Start the engine, check the data flow of the ABS system, select 004 data blocks, the data block has 4 zones, zone 1 data indicates parking time, zone 2 data indicates whether the EDS control function was cut off in the first 20 ignition cycles (and Brake temperature), Zone 3 data indicates whether the EDS / ASE control function is available (related to factory settings), Zone 4 data has no specific meaning. During the inspection, it was found that the data in zone 1 was displayed as ERROR. Looking at the relevant information, the meaning was as follows: After turning on the ignition switch or starting the engine, the ABS control module failed to receive two valid and consistent times from the dashboard Message, you must check whether the fault memory stores fault code 01203. After analysis, the author recognizes this decision and makes further inspection. Use a probe to pierce the 10-terminal lead (green wire) of the ABS control module, start the engine, and measure the voltage of the lead. As a result, there is no voltage, indicating that the instrument panel does not output parking time information to the ABS control module. Replace the instrument panel, and perform anti-theft matching and initial setting on the new instrument panel. After the test is completed, the fault symptom disappears completely, and the maintenance work is completed. <br>Start the engine, accelerate the car to a speed of 30-40km / h, and quickly depress the brake pedal. At this time, the four wheels are locked at the same time, leaving obvious braking marks on the road surface, indicating that the car's conventional braking performance is good. Accelerate the car to a speed of 60 ~ 80km / h and quickly depress the brake pedal. At this time, the four wheels are still locked at the same time, leaving a very obvious brake mark on the road, but the car has no brake deviation phenomenon. The ABS system in the automobile braking system does not work, and the braking system only has the conventional braking function.

起步发动机，查看ABS系统的数据流，选择004组数据块，该数据块共有4个区，1区数据表示停车时间，2区数据表示EDS控制功能在前20次点火循环中是否被切断（与制动器温度有关），3区数据表示EDS/ASE控制功能是否可用（与生产厂设置有关），4区数据没有具体含义。在检查中发现1区数据显示为ERROR（错误），查阅相关资料，得知含义如下：在打开点火开关或启动发动机之后，ABS控制模块未能收到来自仪表板的两个有效且一致的时间信息，此时必须检查故障存储器是否储存故障码01203。笔者经过分析之后，认此决定做进一步检查。用探针刺破ABS控制模块的10端子导线（绿色线），起动发动机，测量该导线电压，结果没有电压，说明仪表板没有向ABS控制模块输出停车时间信息。更换仪表板，并且对新的仪表板进行防盗匹配和初始化设定，完成后试车，故障症状彻底消失，检修工作结束。<br>起动发动机，把汽车加速至30~40km/h的速度，迅速踩下制动踏板，这时4个车轮同时抱死，路面上留下明显制动印痕，说明汽车的常规制动性能良好。把汽车加速至60~80km/h的速度，迅速踩下制动踏板，这时4个车轮仍同时抱死，路面上留下十分明显的制动印痕，但汽车无制动跑偏现象，说明汽车制动系统中的ABS系统不工作，制动系统只具备常规制动功能。

Start the engine, check the data flow of the ABS system, and select 004 data blocks. There are 4 data blocks in total. The data of zone 1 indicates the parking time, the data of zone 2 indicates whether the EDS control function is cut off in the first 20 ignition cycles (related to the brake temperature), and the data of zone 3 indicates whether the EDS /ASE control function is available (related to the setting of the manufacturer). The data of zone 4 has no specific meaning. During the inspection, it is found that the data in zone 1 is displayed as error. After consulting the relevant data, it is found that the meaning is as follows: after the ignition is turned on or the engine is started, the ABS control module fails to receive two valid and consistent time information from the instrument panel. At this time, it is necessary to check whether the fault memory stores the fault code 01203. After analysis, the author believes that this decision will be further examined. Use the probe to puncture the 10 terminal wire (green wire) of the ABS control module, start the engine, measure the voltage of the wire, the result is no voltage, indicating that the instrument panel does not output the stop time information to the ABS control module. Replace the instrument panel, and carry out anti-theft matching and initialization settings for the new instrument panel. After the completion of the test run, the fault symptoms disappear completely, and the maintenance work is completed.<br>Start the engine, accelerate the car to a speed of 30-40km / h, and quickly press the brake pedal. At this time, four wheels lock at the same time, leaving obvious brake marks on the road, indicating that the normal braking performance of the car is good. Accelerate the car to a speed of 60-80km / h, and quickly press the brake pedal. At this time, the four wheels are still locked at the same time, leaving a very obvious brake mark on the road, but the car does not have the phenomenon of brake deviation, which shows that the ABS system in the car brake system does not work, and the brake system only has the function of constant regulation.<br>
