Range Selector Switch
WARNING: This page does not describe the selected car, but rather 43 other vehicles, including the 2006 BMW M3, 2006 BMW 330Ci, 2006 BMW 325Ci, 2005 BMW M3, and 2005 BMW 330xi. However, it is still accessible from the selected car via links, so may be relevant.
The switch is mounted inside the transmission main case on the driver's side. This location provides precise monitoring of the Manual valve position and is sheltered from the harsh environment under the vehicle external of the main case. Adjustment is not required. The range selector switch has 6 wires. The GS 20 provides the switch with 12 volts on one wire (pin 2 of connector X70004). Depending on the range selector position, the switch provides coded high signals over five wires to the GS 20. The addition of the fifth wire (pin 1) is new compared with previous four wire range selectors providing a redundant P/N signal circuit. See Fig 1 .
