奔驰EDW 有故障时的诊断 (Refer to GI80.50-P-051279, V2)：LI80.50-P-051972

本篇按原通告的适用范围、投诉、原因和补救顺序重新编排，便于维修时快速定位信息；具体数值、零件和操作要求可在文末保留的原始页面中逐项核对。

一、故障现象与投诉条件

• EDW 出现误警报以及

• EDW 功能不可用

二、原通告列出的可能原因

障原因

三、检查与补救步骤

障时的环境条件

• 什么时候（几点钟）发出警报？

• 警报出现的频率为多少？

• 从何时起存在投诉？

• 何处出现误警报？

• 环境是怎样的？

出现误警报？

• 在此之前车辆是否行驶过？

• 是否存在温差？

应想到，客户可能在来授权服务中心之前将这些物品取下了。

请在维修文档中附上警报信号源存储器打印稿。

提示： EDW 主控是

车型 171、203、209、211、216、219、221： 后座区信号采集及促动控制模组（SAM）

车型 164、251： 后部 SAM

车型 215、220、230： 驾驶员信号采集及促动控制模组（SAM Fahrer）

4. 只有在读取报警信号源后才能根据需要理解客户投诉或进行一次功能测试。

保护

声波，车型 171： 红外线，车型 209.4 和 230： 雷达）

保护传感器盖板是否牢固固定（如果是一个独立的部件）

况

物品可能导致反射。 这更易触发误警报。

况下，这也适用于中间杂物箱中的金属物品。

保护传感

障代码 82708 73。

6.3 防拖车保护 / 倾侧传感器

，

障引起的车辆位置变化（例如弹簧梁

不密封）

• 检查线束和插针

要时更换防拖车保护传感器

障代码 82566 73。

6.4 玻璃破碎环（对于车型 164、203.2、203.7、211.2、251）

保护传感器插头连接，然后检查对地电阻欧姆值（标准值 < 50 Ω）

• 如果电阻偏大，则检查单个车窗玻璃的玻璃破碎环（标准值 < 20 Ω）

• 如果该数值正常，则检查导线、插头连接和接地连接

要时更换

况下都可以再现的。

障代码：8230C（后窗玻璃破碎传感器）、82A32（左侧固定式侧窗玻璃破碎传感

器）、82N32（右侧固定式侧窗玻璃破碎传感器）、5110C（K/Z* 后窗玻璃破碎传感器）或 51123（K/Z* 侧窗玻璃破

碎传感器）。

6.5 警报器（警报器自行报警以及至警报器的通信中断）（对美国 / 加拿大车型不适用）

障条目。

• 检查警报器（通过 Star diagnose 促动）

• 检查警报器供电，同时也注意馈线和插头连接，检查接地点

括插头连接）

• 借助 HMS 检查通信导线信号（可选择“空调总线 W203”作为规定特性） – 总线（K 线，车型 216 和 221： 局域

须同时激活，这在通过 Star diagnose 促动警报器时可得到确保。

要时更换警报器

要时更换

美国 / 加拿大车型）

要时更换

提示： 例如可能有物品按压在钥匙按钮上，这就形成一个误报警条件（这也可能是另一把车辆钥匙所导致）

6.7 警报信号源存储器中无条目，但反复听到警报

况。

7. 维修提示

7.1 更换警报器或 EDW 主控时，请设码国家规格。

提示：

须功能完好。

• 设码在 DAS 中每个EDW 主控下“调整”下进行。

障记忆之外，还需要删除警报信号源存储器。

保护功能测试

保护传感器灵敏度更高）

4. 将车辆锁止

上方上下移动手臂

提示： 对于带无钥匙起动的车辆： 抓住车门钢板，使车辆不会解锁

7.4 防拖车保护功能测试

2. 将车辆锁止

3. 3 分钟后将车辆一侧升起；当一个车轮与地面不接触时，警报应该会触发
