General Information: General Description

The Transaxle Range Switch sends the shift lever position information to the TCM using a 12V (battery voltage) signal. When the shift lever is in the D (Drive) position the output signal of Transaxle Range Switch is 12V and in all other positions the voltage is 0V. The TCM judges the shift lever position by reading all signals, for the Transaxle Range Switch, simultaneously.
