The transmission manual shift shaft switch assembly, also known as the Internal Mode Switch (IMS), is a sliding contact switch attached to the manual shift shaft inside the transmission case. The Park/Neutral Position (PNP) Switch is integrated into the IMS and connects to the Transmission Control Module (TCM) lead-frame through a short wire harness. The 5 inputs to the TCM from the transmission manual shift shaft switch assembly indicate the transmission gear selector lever position.This information is used for engine start enable, engine controls as well as determining the transmission shift patterns. The state of each input is available for display on the scan tool. The five input parameters represented are Signal A, Signal B, Signal C, Signal P (Parity), and Signal N (Park/Neutral Start Signal). Park/Neutral Signal is sent from the Park/Neutral switch directly to the Engine Control Module (ECM) and is used for engine start enable. The Park/Neutral Signal circuit is not connected to the TCM internally. The circuit uses the TCM as a pass-through connector only. The ECM Park/Neutral diagnostic monitors the Park/Neutral signal circuit to detect low voltage when the ECM expects high voltage and high voltage when the ECM expects low voltage. | Translation - Chinese
手动变速器换挡拨叉轴开关总成，又称为内部模式开关，是变速器壳内手动换档拨叉轴上的一个滑动触点开关。驻车档／空档位置开关集成于内部模式开关内，并通过一小段线束将其连接至变速器控制模块引线框。发送至内部模式开关的来自于手动变速器换挡拨叉轴开关总成的5 个输入信号表明了变速器齿轮变速杆的位置。该信息用于发动机起动激活，发动机控制和确定变速器换挡模式。每个输入信号的状态皆显示在诊断扫描仪上。5 个输入信号参数用信号A，B，C，P（同位），和N（驻车档／空档启动信号）来表示。将来自于驻车档／空档开关的信号直接发送至发动机控制模块并用于发动机起动激活。驻车档／空档信号电路未连接至变速器控制模块中。该电路仅将变速器控制模块（TCM）作为贯通式连接器使用。发动机控制模块驻车档／空档诊断器监控驻车档／空档信号电路以探测出发动机控制模块要求高电压时的低电压值及发动机控制模块要求低电压时的高电压值。 |
