ECM Will Not Accept Factory Passwords

Usage:

826K 2L3

可能原因

  • 不正确的密码请求信息

  • 不正确的密码

建议的措施

检查密码请求信息

密码请求信息必须从正在编程的发动机控制模块(ECM)中获取。 不能利用旧 ECM 提供的信息为替代 ECM 编程设定出厂密码。

确认用来请求密码的信息与 Caterpillar 电子技师(ET)上显示的信息一致。

发动机序列号 - 发动机序列号必须来自 Cat ET 屏幕,而并非发动机信息标牌。

原因代码 - 采用出厂密码屏幕上的原因代码。 原因代码是为特定的用途而指定,因此不可互换。

把钥匙开关转到断开(OFF)位置。 随后,将钥匙开关转到 ON 位置。 尝试重新输入密码。

密码错误

确认输入了正确的密码。 检查每个密码内的每个字符。

如果重新检查密码未能排除故障,则修改用户参数。 将参数从当前值改为其他值后将用户参数重新改回原始值。 事件顺序将改变总修改次数。 新的总修改次数将要求获取新出厂密码。 获取新出厂密码后输入密码。
