 P182E,硬换档,无PRNDL显示

诊断并修复P182E,换挡困难,无PRNDL显示

下列车辆出现P182E,换挡困难,无PRNDL显示的情况可能是由内部模式开关故障引起的。 内部模式开关是我们过去所说的驻车/空档开关的新名称,后来改为变速器范围选择器。

P182E:内部模式开关指示范围无效

IMS在7秒钟内未显示有效的驻车、倒车、空档或行驶范围位置。

内部模式开关的工作原理

该开关有一个滑动触点开关,连接在变速器内的换挡棘爪杆轴上。 开关向变速器控制模块(TCM)发送4个输入信号,以指示变速器驱动器选择了哪个挡位。 当开关断开时,TCM的输入电压为高电平,当开关闭合接地时,TCM的输入电压为低电平。 各输入信号的状态显示在扫描仪上。IMS输入参数代表传输范围信号A、信号B、信号C和信号P。

P182E代码仅在下列情况下设置:

发动机转速大于或等于 400 RPM,持续 5 秒钟。

点火电压大于等于9.0伏。

代码P0101, P0102, P0103, P0106, P0107, P0108, P0171, P0172, P0174, P0175, P0201, P0202, P0203、

P0204、P0205、P0206、P0207、P0208、P0300、P0301、P0302、P0303、P0304、P0305、P0306、P0307、

P0308、P0401、P042E、P0722或P0723未设置。

内部模式开关故障可能导致发动机检查指示灯点亮并存储P183E故障代码。 在某些情况下,PRNDL显示屏停止工作是因为变速器控制模块无法确定您所选择的挡位。 它还可能导致换挡困难,同样是因为它无法确定您所选择的挡位。

当P182E设置时会发生什么

TCM 命令最大管路压力。

TCM关闭所有电磁阀。

TCM冻结变速器自适应功能。

TCM将变速器限制在倒档和5档。

TCM强制变矩器离合器(TCC)关闭。

TCM抑制Tap Up/Tap Down功能。

TCM抑制前进挡手动换挡。

TCM关闭高压侧驱动器。

TCM实现扭矩管理。

修复 P182E

首先检查换档拉索的调整

- 设置驻车制动器并刹住车轮。

- 确认变速器范围选择杆位于驻车位置。

- 确认变速器手动换挡杆处于驻车位置。

- 在变速器上,向前拉动换档拉索上的固定环。 然后松开量程选择拉索调节器夹子。

- 然后将两半量程选择电缆滑到一起,直到消除所有自由游隙。

压下调节器夹,完全锁定调节器夹,然后松开固定环。

向相反方向拉动范围选择拉索的两半部分,检查拉索调节器是否固定。 检查变速器范围选择杆在所有档位选择中的操作是否正常。

确认所有量程的驻车/中性状态

检查PRNDL显示屏是否工作并显示正确的档位选择。 如果没有显示,则用扫描工具检查档位状态。

更换内部模式开关
